KINEMATICS | Serial robot vs. Parallel robot (This is not CGI)
Ғылым және технология
Six degrees of freedom (6DOF) achieved in two completely different ways. The serial architecture of the world's smallest industrial robot from Mecademic (www.mecademic.com) has a large workspace and compact design while the parallel architecture of the Hexapod (also known as a Gough-Stewart platform) can reach extremely high speed and acceleration since all the heavy parts (motors, guides, gearboxes) can be mounted on the fixed base.

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.

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!
As robotic researcher myself, I would say the accuracy of your serial manipulator movement extremely impressive 👍🏻👍🏻

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.

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.

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.
Cool concept
thanks for specific that is not CGI, its so unreal
