Hello, I need assistance in understanding why my robot is controlling itself. It is supposed to be controlled from a laptop keyboard and it works fine at times but at VERY IMPORTANT times it starts to go crazy like its spazzing. I was testing my teams robot in the operating room at our local hospital to see if it would work with the robotic microsurgery equipment but it kept going crazy! We are trying to use the arm to help with the irrigation that goes on during surgery. Attached below is a video of the situation but the arm gets worse at times. I figured out that one of the arms joints is most likely the cause but it would be helpful to here other peoples opinions to help solve this problem. Please respond asap, it would be much appreciated!
