You can see in the close ups that the tips of the axes are shaking a bit. Depending on application this may be a non issue. If you're doing pick and place operations, it's great. But if you're doing machining, then it's pretty bad. That's why very accurate robots cost a lot of money.
I'm not saying that this isn't impressive, but have you ever seen a full size multi ton industrial robot at work? Some models achieve repeatability of a few hundreds of a millimeter.
The end of the day, engineering is tradeoffs. For these bots to move as rapidly as they do for the price point they are at, they had to sacrifice some accuracy. There are ways to mitigate this.
I think this is the first time I've seen a stewart platform type machine with the axes paired up like that - for a moment, I thought it was simply a doubly-braced delta machine until the pairs moved in opposite directions for the rotation. Absolutely brilliant!
This is a robot dance battle. I feel like serial bot won. Those were some sick moves. Plus, I don't think parallel but can do more than one full rotation.
But as in th description, the problem of serial is that motors are on the arm: so heavy, so slow. Parallel ones allow all the heavy elements to be motionless, thus way way faster actions.
Most serial robots also cant do more than a full rotation. This is because of wiring sent though the arm. Most even have a 30 degree or so dead zone on Axis 1. The only axis that could have unlimited rotation is the wrist axis (6 on a 6-axis) however you put tooling on the end of robots that need pneumatic or electrical control. So in practice all axes on a serial robot are maximum 0-360 degrees.
@@Komrade_juice There is a well known solution to the continuous wire limitation. A bit more complex, but reliable and well tested in brushed motors, and in 3.5mm jacks...
*trap beat starts playing* EPIC RAP BATTLE OF HISTORY!!! SERIAL ROBOT V.S. PARALLEL ROBOT !!! *mechanical whirring noices* *Some more whirring* *Whirring sounds* ... WHO WON?!? WHO IS NEXT???! YOU DECIDE!!!!!!!!
While the parallel 6-DOF is impressive from a mechanical view, I have a slight feeling that it's range of motion is rather short compared to the other one. But I was really surprised how it did the Z rotation, I thought it would just have a spin motor in the top.
The workspace of the parallel robot is definitely smaller than the same size serial architecture. Parallel, however, has a number of advantages, such as extremely high speed and acceleration, high rigidity, better accuracy (depends on the architecture).
@@OleksandrStepanenko Interesting, is seems like parallel robots would have fewer kinematic singularities and more optimal power consumption due to the use of prismatic joints but the Jacobian must be more difficult to formulate. Seems like you would end up with a differential solution?
As an engineer who is much more comfortable in the machine shop than writing code (hint: I don't actually code, unless shell scripts count, LOL) it is the software driving these beautiful little machines - keeping track of the geometric center of the model and doing the complex geometry to calculate the necessary motions... mad respect just cuz I can't do it!
The international docking standard soft capture system uses 6 linear actuators in a parallel arrangement to move a ring that helps guide a spacecraft into the docking port if not perfectly aligned.
The fact that people would think that this is CGI says a lot about how advanced CGI technology has become. If this was CGI it would be even more impressive than the robot tech displayed here.
To be fair the room this is filmed in is also lit in a weird way that reminds of CGI using simple lighting. It's not really CGI being advanced as it is the way it's recorded making it seem "low quality" in a way

How does the strength of these different mechanics compare assuming they run on the same motors? I presume that the parallel has more torque and force, but sacrificing the range of motion

Yes, it's mine :) It shouldn't be too complicated, especially if it's a prototype. For a motion simulator, it should be a little different, but still not too complicated.
this was filmed so well that it looks like it was made in blender, but i don't think it was because there some details like the cables and the lights on the right robot's base
I was like "Not CGI. I'm going to bust this so hard". Why on earth you would record these bots in studio/scene so clean and good lighting it is indistinguishable from CGI in lower resolutions, so you need to separately say it ain't CGI? Stunningly cool tech tho guys!
That's a good question 🤔 To be honest, I was just trying to get a picture that pleases and inspires me, but then I realized it looks so similar to CGI in low resolution (on a 5K screen, by the way, it doesn't look that perfect). On the other hand, it is only a matter of time before CGI becomes indistinguishable from reality. Thanks for your comments.
As a millright, I look at these things from the perspectives of reliability, longevity, maintenance/repair costs. The "parallel" machine has more interchangeable parts, fewer discrete-fit parts. But then again, it looks like failed parts will have to be replaced as full sets since you don't want to introduce asymmetries. Awesome demo stuff on the design benches doesn't always work so well in real world applications.
The two 3-axis models can form opposite corners of a cube (with 6 edges left to the imagination), could you have the two robots synchronize movement to manipulate that cube?
You could in theory do that. The best way I can think of however you be to have one mounted upside-down over the other one, as that would allow the greater range of motion for the cube.
Six degrees of freedom are 3 translational along x, y, z and 3 rotational about x, y, z (6 is the maximum in our three-dimensional world). The axes refer to the number of joints of the robot (can be more than 6).
Between the two control systems, are there limits to the degree of freedom? Like based on the above video, it would appear that the parallel control system would not be able to do 360 deg rotation around at least two of the axis? Not suggesting that it definitely makes it an inferior system as many usage case do not require it. Just wondering about the specific limits of it. Or am I missing something? Thoughts?
The parallel system would have more limits for sure, but it's much more efficient and seems like an easier way to improve precision over the serial design. One limit would be that the end effector can only be pitched or rolled +-90 degrees from equilibrium, since the arms that connect to it can't invert and work on the opposite side of the plate they connect to. It would also have a limitation in how low the end effector can go and may even get stuck in the right conditions. That could happen if it goes so low that the arms are all nearly parallel to the base. In that position, the stepper motors would have minimal mechanical advantage and would be at a huge disadvantage if the end had any significant mass attached to it.

Six degrees of freedom are 3 translational along x, y, z and 3 rotational about x, y, z (6 is the maximum in our three-dimensional world). The axes refer to the number of joints of the robot (can be more than 6).
Damm boi why is this so satisfying
So who wrote the music and was it designed with intention for the robot sounds in mind?
The part where the serial robot says "0011011010001110110010010011001101101" is my favourite.
it can make the same movements only if they are separated, they can't do a different position while holding a different inclination
I can't believe how many comments fell for this obvious CG well done
This is not CG www.youtube.com/@OleksandrStepanenko/community
why would anyone think that is CG? These kind of robots have been around for well over 30 years at this point.
People think rocket launches are CGI. People are extremely dumb.
Between the two control systems, are there limits to the degree of freedom?
Like based on the above video, it would appear that the parallel control system would not be able to do 360 deg rotation around at least two of the axis?
Not suggesting that it definitely makes it an inferior system as many usage case do not require it. Just wondering about the specific limits of it.
Or am I missing something?
Thoughts?
The parallel system would have more limits for sure, but it's much more efficient and seems like an easier way to improve precision over the serial design. One limit would be that the end effector can only be pitched or rolled +-90 degrees from equilibrium, since the arms that connect to it can't invert and work on the opposite side of the plate they connect to. It would also have a limitation in how low the end effector can go and may even get stuck in the right conditions. That could happen if it goes so low that the arms are all nearly parallel to the base. In that position, the stepper motors would have minimal mechanical advantage and would be at a huge disadvantage if the end had any significant mass attached to it.
Very cool stuff, but why not run them together?
Thanks! It's not easy to synchronize movements perfectly because the robots use different control systems.
