This was filmed during the 2021 lockdown when a travel radius limitation was introduced to reduce spread. That's why it wasn't appropriate to travel to and film at the beach. They are no longer in effect.
Ahhhhhh. See I came here to ask what changes could possibly make it to where you werent allowed to have an electric arc car on a sandy beach. I was like some weird motorized vehicles on the beach law? Some environmental protection law? Covid. How could I forget covid. Makes perfect sense lol
The reason it's loud is because of gearing. They use small DC motors and a plastic spur gearbox. I love the look and scale of it. I wouldn't mind getting my hands on a cad drawing of one.
I have a question why is it that my pla when it’s going to finish the print it start stringing or little spot like it not conecting. It only happen at the end. Can you help.
When I saw the spiked wheels continue to drive while upside-down, it reminded me of a demo of police robots that I saw a few years ago. They had one, not much larger than your platform, that was made to be tossed into a building. It didn't matter how it landed - it could drive either way.
And it reminds everyone else of Robot Wars, where robots capable of operating in either orientation are a common defence against flipper weapons and wedge-bots.
Hi, There is this stuff where you can "rubberize(?)" your metal tools so they have a rubber grip, what if you put that on the edge of the wheels to give them some grip?
Ngl I was giggling seeing the concept of my wheel's design performing so well. Downside - damn slippery TPU. Really appreciate the ego inflation going on there. Also damn sorry my design embued your rover with my slightly pervy sense of humor.
While I know you probably don't want to spend dozens of hours printing various wheels, but I'd love to see more viewer designs put to the test. :) I bet there'd be some really fascinating designs to overcome the traction, even using slick PLA.
I know you might think you're a pretty boring person but not everybody can make playing with remote control cars fun to watch 😆 I love your videos man, thanks 😁
No matter what many people think, military designers are not stupid and there was a reason why tracked vehicles were adopted due to there offroad capabilities. No type of wheel can ever come close.
Reminds me of the old Tyco Rebound. Its a bit silly but I'd rotate the axles outward and stick some 2.8 monster truck wheels on if the gearing doesnt burn out the motor and allow it to run upside down like the Rebound
V1: low fast fairly simple V2: more ground clearance, better motors, gear box V3: suspension, monster truck tires V4: tracks without suspension V5: half track with suspension on the tires and tracks with all previous aforementioned upgrades. V6: some sort of system to allow for vertical movement like a grappling hook launcher
I made a tank out of ABS, everything is printed solid at 98% infill, it has metal-toothed pullies as you find in a 3D printer with toothed belts as the reduction drive with 2 quadcopter motors. It has double reduction (i.e 2 belts per motor 1:16 reduction ratio) onto a metal shaft, a long bolt, using the hex bolt head to mesh with the ABS drive wheels (sprockets). The other only metal part is the roller bearings used on the main drive shafts and on all idler wheels. The shafts for the idler wheels are printed in ABS and 4mm in diameter with a slight flat on one side so it is printable. The idea works really well and is really strong. The shafts are stationary with the wheels spinning around them. Everything else is ABS printed (apart from screws and nuts holding the various parts together). There are 2 ECU's to drive the quadcopter brushless motors and the ECU's are controlled by an Arduino nano fully programmed by me (no Arduino libraries except for the NRF24L01 library). I find that printing things flat and bolting them together gives really good strength. It's a bit like cutting it out of plywood or a sheet of metal. The tracks are printed in ABS using nylon 3D printer filament as pins to hold them together. The quadcopter motors cost about $15 AUD each and the ECU's cost about $20 AUD each. The ECU's were reflashed with Simon K software to give forwards and reverse on the motors. The Arduino nano cost about $4 AUD and the NRF24L01 cost about $4 AUD. But I used a whole roll of ABS at about $35 AUD. Many parts were printed several times with minor tweaks to the design. I also made a bulldozer with a NEMA 17 stepper motor in the track frame and a single reduction belt drive (1:4 ratio). The motor has a metal pully (from a 3D printer) with a toothed belt but the sprocket end is printed in ABS with both the large-toothed pully and track drive sprocket as one unit (contained within the width of the track) this meant I could use a stationary shaft printed from ABS just like on the idler wheels. The belt is inside the track frame. By mirroring the process for the other side I had two tracks (no drive motors within the body) with wires from the track frame into the body. This gave me room to put a 3rd NEMA 17 inside the body to raise and lower a blade on the front. Again I used an Arduino nano to control all 3 stepper motors using my own code (no Arduino libraries except for the NRF24L01 library). The NEMA 17 's cost about $4 AUD each and each NEMA 17 has a stepper controller board (DRV8825) I also used voltage step-up boards to step the drive motor voltage up to 26 volts. This lets me run the NEMA 17 at 1,100 RPM for a somewhat slow top speed, but hey, it's a bulldozer and they are slow. I built a remote control (from ABS) using an Arduino nano with an NRF24L01 wireless board with a screw-on antenna. I used hall effect sensors to read the joystick movements. The remote has automatic trimming on every axis (two joysticks with 2 axes each). Both the tank and bulldozer is steered by only one joystick (forwards and backward, clockwise and anti-clockwise turns). The bulldozer uses the second joystick to raise and lower the blade. Both the tank and bulldozer use NRF24L01 wireless boards with the antenna "printed" on the circuit board, to be controlled by my homemade remote. If only I could post photos!
Someone may have already suggested. What about create a gear and idler wheel for the new platform and print tracks and see how the new platform behaves against the tank?
If you used a spray rubber coating on some of the smooth plastic wheels, I'd be interested in the results. Might give more tractions. Another idea - wheels with variable but even width. Would allow you to climb narrower surfaces that are above and below and drag the cart towards the grip
Looks like the brushless motors struggle at low rpm. That's just super hard to avoid with sensorless comutation. Also, try adding a v-tail mixer and tail-rotor gyro to the platform. I'll transform you into a drift master and MASSIVELY increase control.
The wobbly wheels being good on rollers kinda makes sense. Because they aren't just pushing in line with the platform, they are also acting kinda like a with a screw action where they are pushing sideways as well which moves it forwards
Quite fun to watch :) If indeed your gears got damaged you can use helical gears next time. With more teeth in contact at any time they can handle higher torque. With 3D-printing even double helical gears are easy to manufacture. That way you don't even get axial forces as a tradeoff.
Back in the early 90's I had a Tyco Fast Traxx that was quite the unit. It did have 2 limitations, ground clearance was not very good and it was prone to getting stuff lodged between the track and drive wheels. But the big problem was a weak gearbox. After minimal run time it would start loosing teeth and have to be replaced.
It would be interesting to see the wobble wheels with a soft, sticky rubber tire. The combination of traction with eccentric motion might be very effective.
Some years ago, there was a huge debate in Canada about whether we needed true tanks for our army, or could do the job with light armoured vehicles. LAVs are not only cheaper to purchase, they're easier and cheaper to operate because they have wheels. In the end, experience in Afghanistan convinced the government there was still a need for track-laying armoured vehicles. The bit with the EAT06 reminds me a lot of the videos being passed around by the pro-tank side. :)
Adding a extra set of tires would divide the load of the RC car you made over the car. Also, it would add more weight to it, providing more downward force, making more traction. You can also do the same thing with lead sinkers or under mounted rails (like a bobcat, a Johnny cart, or something along those lines)
I was experimenting with TPU wheels. Printed on the side, with no top or bottom layers and hex of triangle or gyroid infill so its soft and complient. it had a tractor texture on the outside. ajust the infill % and perimiter layers to change stiffness.
Did anyone else get a "young kid in backyard, playing make-believe" with the obstacle course? Fun video and great finding a solution to "can't leave home"
I’m glad you reset and tried again sometimes. Even with real off-roading while really having the proper setup for the terrain, it doesn’t always go perfect the first time and you have to try again. I always hate when people “testing” something are so rigid and rushing so much, that they give something 1 try and if it doesn’t work, declare it a failure even though it may have been their control that was the problem and not the thing they were testing.
I wonder if adding some sort of suspension to the wheels could help them get over some of the obstacles and help with all the dumps. Maybe adding some weight to it as well to ensure it is making very firm contact with the surface it is on (and increasing the weight required to send it flying).
I got one of those tank things before for snow and it turns out that the moment it looses too much traction it just stops so it doesn't work on ice or snow most of the time, my guess is the gyro that makes it go straight freaks out. From what I can tell the platform you built doesn't need any extra gyro sensors, so your robot platform would beat it there.
I think the reason why the rollers work well with the angled wheels is because they are putting in the same energy as straight wheels would, but straight wheels make the rollers roll backwards with the same energy, as angled wheels dont make it go backwards as much?
ok one thing you need to add to that platform in order to properly test the performance of wheels is some fairly basic swing suspension so the wheels can swing out from the centre as weight is applied simply to allow them to better contact the ground as if even one is off the ground no matter the wheel design you will lose a very large portion of your control
You could probably do independent 4 motor atv style tracks on your platform. Main sprocket would connect to motor. Could probably print the track tread out of tpu. There are several thingiverse projects like “no tanks”, mini track loader, “rc snow tracks”. Each wheel would be replaced by an independent track unit.
One thing that you should test is Platform configuration, I mean, its better a 4x4, 6x6 or 8x8 with what wheels in what terrain. A lot of offroad vehicles add more axles to better distribute the weight, so I do wonder if that can be seen at scale
The 2021 Summer Olympics have nothing on this. Speed, performance and stamina and possible sabotage with banana leaves. The encounter with the garden hose is what lifted it to achieve Gold.
Has anyone else realised that Angus looks really fit? Like how do you do it man? Looking quite snazzy in those shades btw Also I really enjoyed watching the video :D The names of the obstacles in the course show how much you think these things out haha
"King Blob" might not have the most informed understanding of what constitutes "fit". Angus should be 0.66 of his current mass to be considered close to fit. Just fact. Even Angus was kind enough to mention he's not fit here. These lockdowns are brutal on our overall health.
@@mozkitolife5437 Actually, you are correct. I infact am not an expert on what and what is not considered fit. It was just Angus's appearance of fairly well built that led me to that conclusion.
@@kingblob17 No worries. I'm not trying to be insulting. I guess there's fit for lifting and fit for stamina etc. Angus is neither of those. Again, not insulting. This is fact. Sorry for discussing your physique, Angus. I'm in no better shape.
VIDEO IDEA: 1. Make your own tank tracks out of 3D print to be used on your RC platform. 2. Try alternate track systems. Like your multiple versions of wheels
Not trying to sound redundant or stupid in case it's already mentioned but your wobbly Wheels looks like it would do well on the surface of a lake. Because they move like a water serpent. Just something to keep in mind unless that's already been mentioned
This was a fun video to watch, but then so are all you videos. Each video you release I learn something and have fun. Thanks for teaching a 54 year old dog new tricks. LOL :)
Future idea: Using your custom design, some large toothed wheels that are taller than the body to allow for inverted driving + tracks connecting front and rear. Maybe even with additional rollers in the centre region so that the side profile of the tracks is a squished hexagon.. sort of like how the side profile of the cheap tank looks but on both top and bottom. Apart from the difficulty of turning on the spot (should be overcome by the more powerful motors you have on that platform) I reckon it could drive over damn near anything
With the lockdown going on, you should send it to the shops to do your shopping to avoid contact. Bonus marks for remotely driving it all the way to the beach and back without leaving your house :)
Those Flex wheels need to get patented... Completely serious. The tests were unfair comparing to the tires and tank tracks due to their rubber construction. Solid plastic tracks would've undoubtedly spun on the rollers and seesaw, too. It'd be VERY interesting to see the Flex if made from rubber, or coated somehow in a thin film of soft rubber. Spray on rubberized vehicle "undercoating", which in North America is applied to vehicles to protect from rust in snowy/icy winter months (de-icing roads is with salt or chemical, or worse, a mix of both). Although, rubber tool handle dip might be better for traction, it's thick and that'd be problematic for applying... Though perhaps a modified wheel with one less "link" and more gap in between to make up the difference, might work, allowing the handle dip to run off instead of clogging... But yea, pure genius design and hats off to the creator of them for thinking outside the box! There is SO much potential for them, especially if they can be molded, since more complex designs can be used and no support material needed - say, diamond shaped, which would act like studs, for improved soft-surface (off road) traction.
I don't know how open you are to suggestions but maybe putting a small amount of the liquid grip used to repair the rubber like grips on tools would be useful for the edges of the 3d printed tires. I'm not sure what brands you have in Australia but generally you can find it in hardware stores and it is used to coat tool handles for better grip.
well a continues track will almost always win, since it maximize contact while keeping the center of gravity low. the downside? failure in 1 point means failure in all. you can get a compromise of performance and avoid a single point catastrophic failure, by adding more small wheels, instead of having lots of large ones. XD
Seems like the issue here was common... no rubber. It would be nice to see this run again, with rubber applied to the wheels... maybe even "sticky" rubber, like climbing shoes. Glued on, painted on, whatever... let's see what friction assist does with each wheel type.
This was filmed during the 2021 lockdown when a travel radius limitation was introduced to reduce spread. That's why it wasn't appropriate to travel to and film at the beach. They are no longer in effect.
Will you be testing these on the beach now?
Ahhhhhh. See I came here to ask what changes could possibly make it to where you werent allowed to have an electric arc car on a sandy beach. I was like some weird motorized vehicles on the beach law? Some environmental protection law?
Covid. How could I forget covid. Makes perfect sense lol
Travel radius is something that never made sense to me, nor did COVID ZERO.
Super late on this but I just watched the video and wondered if you would put some screws through the white flex wheel to give it traction
Sorry your government is like it is, seems the jailers are back in charge in australia
Having said that, the obstacle course was a lot of fun!
The reason it's loud is because of gearing.
They use small DC motors and a plastic spur gearbox.
I love the look and scale of it.
I wouldn't mind getting my hands on a cad drawing of one.
Every episode, I enjoy this series even more! I can't wait to see how well those gears survived.

Yeah, it's a good plan!
I like these hobby meshing videos. It’s cool seeing fresh ideas for projects that might be obvious to some, but others may not have ever considered.
16:00 To be fair to our Dodo friend, he shrugged off that hit pretty well 🤔
I got on to comment the same thing. The tank may have dominated the course, but he couldn't defeat the extinct bird.

Printing some square knobs on the ends of the expanding wheel fingers could add weight to increase the centrifugal force and traction when expanded.

I would be curious how the hard 3D printed wheels do if you did something like glue a timing belt to the circumference or something.
Skin a R/C tire and put it on the outside. We just to cut and patch together different crawler tires back before they offered millions of options.
Best Spectator Ever! Would love to see some tracks printed in TPU and hard plastic with different treads. Maybe some sort of interchangeable bits?

Not trying to sound redundant or stupid in case it's already mentioned but your wobbly Wheels looks like it would do well on the surface of a lake. Because they move like a water serpent. Just something to keep in mind unless that's already been mentioned
This was a fun video to watch, but then so are all you videos. Each video you release I learn something and have fun. Thanks for teaching a 54 year old dog new tricks. LOL :)
Awesome video.
Keep on living your dreams.

For 3d printed gears, do 100% infill, added void will reduce overall strength.
Lockdown is the mother of desperation Angus. Nice job.
Having a higher gear ratio would help say for example a 3.55 diff would have faster speeds but less torque than a 4.10 diff
Future idea: Using your custom design, some large toothed wheels that are taller than the body to allow for inverted driving + tracks connecting front and rear.
Maybe even with additional rollers in the centre region so that the side profile of the tracks is a squished hexagon.. sort of like how the side profile of the cheap tank looks but on both top and bottom.
Apart from the difficulty of turning on the spot (should be overcome by the more powerful motors you have on that platform) I reckon it could drive over damn near anything
Innovative use of lockdown, Angus. I don't expect anything less from you. Very interesting physics with mundane objects 👏
Excited for the next set of wheels! The obstacle course is perfect for your robotic platform and the crazy wheels!
The Foliage Fortress!
The Tiles of Trepidation!
The Rollers of Retribution!
...and a seesaw
Friction doesn't really care about weight or shape, it's mainly cares about the surface.
The more even/flat it is, the worse the friction.
I feel like those flexible wheels would work really well on a fast RC like an Armma Granite or Traxxas of some sort. Love these experiments!
With the lockdown going on, you should send it to the shops to do your shopping to avoid contact. Bonus marks for remotely driving it all the way to the beach and back without leaving your house :)
I've considered something along those lines! My RC transmitters don't have the range but maybe something using the 4G network could do the job.
more lockdowns ?..ffs 🙄
Tip: Play this on 1.5X speed and this is the perfect video!
The fact that you live in Australia and didn't call the video '' crazy wheels VS my outback'' astonishes me
Those Flex wheels need to get patented... Completely serious. The tests were unfair comparing to the tires and tank tracks due to their rubber construction. Solid plastic tracks would've undoubtedly spun on the rollers and seesaw, too.
It'd be VERY interesting to see the Flex if made from rubber, or coated somehow in a thin film of soft rubber. Spray on rubberized vehicle "undercoating", which in North America is applied to vehicles to protect from rust in snowy/icy winter months (de-icing roads is with salt or chemical, or worse, a mix of both). Although, rubber tool handle dip might be better for traction, it's thick and that'd be problematic for applying... Though perhaps a modified wheel with one less "link" and more gap in between to make up the difference, might work, allowing the handle dip to run off instead of clogging...
But yea, pure genius design and hats off to the creator of them for thinking outside the box! There is SO much potential for them, especially if they can be molded, since more complex designs can be used and no support material needed - say, diamond shaped, which would act like studs, for improved soft-surface (off road) traction.
Lockdown has driven Angus over the edge. Masterwork in amusing yourself with you have on hand.
I don't know how open you are to suggestions but maybe putting a small amount of the liquid grip used to repair the rubber like grips on tools would be useful for the edges of the 3d printed tires. I'm not sure what brands you have in Australia but generally you can find it in hardware stores and it is used to coat tool handles for better grip.
well a continues track will almost always win, since it maximize contact while keeping the center of gravity low. the downside? failure in 1 point means failure in all.
you can get a compromise of performance and avoid a single point catastrophic failure, by adding more small wheels, instead of having lots of large ones. XD
Bruce, my cat, loved this video.
OwObotics... I swear this timeline is cursed
Seems like the issue here was common... no rubber.
It would be nice to see this run again, with rubber applied to the wheels... maybe even "sticky" rubber, like climbing shoes.
Glued on, painted on, whatever... let's see what friction assist does with each wheel type.
