A tank based wall climbing robot.

Goal: Develop a wall climbing robot using treads to obstain a constant, higher contact area.

Approach: Use a tank design to climb a steep surface with Van der Waals forces using a tacky polymer as treads.

Benefits: Simple design shown to work in many places. Successful climbing with only one actuator (for straight line motion), two actuators for steerable motion, or another actuator for an active tail.

Current Status: Multiple tank climbing robot prototypes were built and tested. Tankbot is able to climb smooth surfaces and make transitions between them, including external. The most recent prototype has an active tail for better climbing ability.
