Screenbot climbs vertically and inverted on Screen mesh using spines. Using a simple 1-DOF drive system, Screenbot’s leg linkages move the legs through a predefined gait which causes each foot to pull inwards once it has made contact with the screen.
The simple drive system can be seen in this picture of the underside of the robot. By chains and sprockets, all six legs are driven by a single motor.
