The UT Campus robot is having some problems at the Hannover Messe. On the first day it drove around until lunchtime but now protoFROG is at a standstill. This is an outdoor robot with a lot of traction power and the loose-laid carpet is causing the motors to overheat during rotation. Although, by the look of it there is not always that much room to manoeuvre, anyway.

The FROG robot was defined to run outdoors, specifically for the EU project in the Lisbon Zoo and in the Royal Alcázar in Sevilla. As the robot must not only navigate the various terrains at these sites but also be able to turn on the spot the project has been having some difficulties with their choice of tires. What would you choose for a  100 kilo robot that has to handle clean-swept tarmac and paving, either of which may later be strewn with olive stones from the trees. This is the terrain in the Lisbon zoo – and the robots mission also includes some inclines and ramps. Then move the same robot to Sevilla where it has to go from neat paved courtyards onto tiled or marble floors.

And in the past two weeks, protoFROG has had to cope with gravel strewn tarmac, TV studios, and now, loose-laid carpet. That’s a lot to deal with for a prototype.
