In "Spike", a touch sensor at the end of the stinger provides the logic to stop a motor when it is pressed. How about without a touch sensor? How can the motor/rotation be programmed to provide tension or force feedback? If I tell the motor to move (...) (18 years ago, 5-Mar-07, to lugnet.robotics.nxt)
