Hey quick question, what wires are you using to attach to the motor? Also what part is used to attach the motor to the wires? I love your build and my classmates and I are building it for our senior project
Typically the wire and connectors are included with the motor, like in this listing: www.aliexpress.com/i/32932735768.html I soldered longer wires to the end to extend them to be long enough to run through the arms.
@@wildwillyrobots Hello, are these motors able to be purchased on another platform such as Amazon? Or are these exact ones only available on Aliexpress? Thank you!
@@wildwillyrobots i and my team loved this project and is planning to build this.. but i am finding some difficulties.. is the .stl of the part used inside the "gear_servo.stl" available? i didnt find it.. also i am finding it hard to get the alternative of tyres as its not available here. Is there any .stl of the tires available..i am planning to print it using TPU
@@thebeanieboochannel6483 It is a 25mm gear DC motor. I think it is commonly called JGA25-370 or 25GA370. The one I used is 6V 130RPM. I use one with encoder, because my primary use is autonomous driving, where I need to know the position of the motor precisely. If you just want to remote control it, you probably don't need the encoder version.
@@bhagya.s1584 Are you talking about the white servo horn? I don't have a drawing of this. It is just what was included with the servos. If you look at www.printables.com/model/194299-stair-climbing-rover/remixes someone created a TPU tire. I'm havent tried this myself.
Good question. If you look at 11:05 you will see 2 small gears fixed to the arms, and one larger gear being installed between the two smaller ones. When all wheels are touching the surface, the arms will not move, so the two small gears does not move. That in turn means that the larger gear cannot move. The larger gear is fixed to the frame of the body, and therefore the body cannot rotate around the main axle of the two arms. The purpose of this "differential" gear is to make sure all wheels are touching the surface. It can be seen at 11:28, that if the arm on one side goes up, the arm on the other side will go down. This makes the force on the wheels the same on both sides when driving in rough terrain.
@@yannmassard3970 Yes, the body will tilt with half the angle. Nasa uses the design on their Mars robots, but implemented slightly differently. If you look at this picture en.wikipedia.org/wiki/Rocker-bogie#/media/File:Mars_Science_Laboratory_wheels.jpg you can see a black bar on the top of the rover. It is connected to the main arms, and serves the same purpose as the internal gear in my design.
I don't remember exactly. But most of the design has features that are 2-3mm thick, meaning that most of it will consist of walls and little infill. So, you don't need high volume infill.
Hello great design! Can you please tell whether if you 3D printed the wheel grip or you bought it? If you bought it can you please share the link for the same?
By wheel grip you mean tire? Yes, that was bought. Model is BS701-002T but seems to be hard to get. There are some alternatives in the comment section here: www.printables.com/model/194299-stair-climbing-rover/comments
Look at the comments at Printables:. www.printables.com/model/194299-stair-climbing-rover/comments There are mentions of different ones, that should fit, but no one has confirmed that they work, so I didn't add them to the parts list.
Hi this a beautiful design and as a college student it makes me feel like trying it out. So can you please explain or give us a circuit diagram of the electronics connection part sir. its a kind request please sir.
My electronics setup is a bit complicated, because I use it for autonomous driving. If you just want to remote control it, it can be done much simpler, but I don't have much experience with that. I would suggest, that you try to contact others, that have built it. Look at the comments section at Printables here: www.printables.com/model/194299-stair-climbing-rover/comments There is also a link to my custom PCB for the electronics, but again, that is most likely overkill for remote control.
I build it from parts I had laying around, so I don't know the exact amount. I guess in the range €200-€300 depending on if it is manually controlled or autonomous driven.

Fantastic! I can imagine all the iterations of the different systems and hardware design involved in this.
Actually not that many. Started by designing one wheel assembly, and build on top of that. Some parts took a few tries to get the tolerances correct.
@@wildwillyrobots Those look like pretty high-torque final drive gear motors - are they 6V or 12V? Also, luv the steering setup.

sorry it s probably a stupid question, but why is it that the rover body is staying perfectly horizontal, and not tilting forward ?
Good question. If you look at 11:05 you will see 2 small gears fixed to the arms, and one larger gear being installed between the two smaller ones.

“How did you find this white part?” For servo
I assume you are talking about the part at 6:40? It is included with the servos, but I have cut the ends of it slightly to make it fit in the gear.
