I just got a JD Revolution robot today for my robotics programming class. I assembled the robot and ran through the tutorials. When going through the initial tests with the robot, I noticed the right gripper servo would not move. I have checked the connections and everything else on the robot appears to be working fine. Would this be a defective servo in the gripper, or could it be something else? My class enjoyed experimenting with the robot today and we are excited to see what we can do with it over the remaining few weeks of the semester. Thanks!
