There are probably at least as many ways to construct a robotic arm as there are uses for them. In the case of [Thomas ...

The curved linear motor at the bottom (Teta 2) enables full rotation of the robot, while the second linear motor (Teta 1) lets the robot arm pivot by more than 68°.

ENGEL has now developed a high-precision load cell for inline weight measurement that can be integrated directly between the rotary axes and the end-of-arm tooling of a linear robot.
