Pretty cool arm control. We went from joysticks to this 'arm' which is attached to a human arm....to control the bot arm....much more intuitive to control. The human 'arm' has pots on the wrist (controls up/down wrist), elbow and two on the shoulder: one to control the upper arm and the other to control turret rotation. The 'arm' has a joystick handle for the hand to grasp and use buttons to enable/disable the arm and also to enable/disable turret rotation. In addition, joystick is available 'just in case'. There is a cable that runs from the back of the vest to the OI and splits to two of the game ports for button and pot input and also LED status lights implemented on the joystick handle.
We saw several examples of arm control in the regionals using the same concept both laying flat on plexiglass as well as standing up. We went the next step and just attached it to a human.
Enjoy!
