I noticed a video of one of the lynxmotion arms playing checkers. I have an industrial model arm that does the same thing, but as the arm is old and overpowering I’m thinking of switching to lynxmotion’s arms. The current arm I have plays checkers by looking at the board with a camera and determining the positions of each pieces. I was wondering how the arm I saw in the video did it.
The video was not a working chess playing machine, but rather just an example showing the arm could reach the pieces and reliably manipulate them. 
ah, but would the arm be capable of doing such thing? All it needs is to be able to connect with a webcam.
Should be no problem. I was able to program a Lynx robot arm to reproducibly locate the gripper to a 3-D specified point within about .1 inches accuracy. (It did take a little fancy programming and an overall system calibration).
