To start it, you either press the button labeled 'Start' on the station, or if you are having teleporting problems you can enter the robot and press the button on the rear and ride it, like in the GIF. It will halt upon it detecting an obstacle. You can manually halt it yourself by activating the latch on the underside.
To reset, you simply toggle the marked button on the underside to open the right claw, fly it away from the rungs, close the claw, and redock.
This is primarily intended as a proof of concept, so do you think this kind of technology is useful?
