Inspecting the condition of dykes and other sea defense structures is typically a task for a team of robots. They consume a lot of energy to move across the dykes, perform tests, and communicate the results for six hours a day. Because charging stations are not a realistic scenario, University of Twente researcher Douwe Dresscher looked at making the robot as energy autonomous as possible. He obtained good results by having the robot store mechanical — rather than electrical — energy, and by introducing an innovative automatic gear box. The gear box is a modern version of the “variomatic” model used in Dutch DAF automobiles. While the variomatic uses a belt drive, the inspection robot uses two metal hemispheres.
