Rover inserting peg

The Interact Rover at ESA’s ESTEC technical centre, under the remote control of ESA astronaut Andreas Mogensen up on the International Space Station, during an afternoon of experiments on 7 September 2015. Andreas was tasked with using the rover to place a metal peg into a hole with just 0.15 mm of clearance. The peg needed to be inserted 4 cm to make an electrical connection.
