I am considering purchasing an AL5D to accomplish a task in which a pen is mounted to the gripper and the arm would in essence draw with it. I am just interested to know if the AL5D is capable of such precision. The arm would be programmed in C/C++ via a serial port. In the videos available online, the arm exhibits quite a jerky motion, I am not sure if that is attributable to inertial effects or programming the arm’s movement. In essence I would like the arm to be able to trace out smooth path, initially in 2D, potentially in 3D.
It’s important to understand the limiations of the arm and the RC servos used as part of the AL5 robot arms. As you get farther away from the base, the accuracy decreases. The accuracy is also affected by the load, as well as the voltage. As such, we do not have any specific “accuracy” ratings. It is best to take a look at the AL5 videos on YouTube to see their capability. A line drawn using such an arm would visibly not be perfectly straight, nor do we have any significant ways to improve the accuracy without adding additional tracking / products. Near the base, the accuracy would be around 2mm, and as you get farther away, it can be around 5mm.
