Strengthen Your Robot With Sugru
In our hackerspace www.MADspace.nl we have build a robot which has won a prize (see url: http://hackaday.io/project/740-mars). But unfortunately the material is weak and can break when driving the robot too hard against the wall. With Sugru you can make great bumpers for your robot on wheels. See below:
Find the Weakest Parts of the Robot
Press Sugru Softly on the Weak Points
Repeat Adding More Surgu Until All Weak Parts Are Strengtened
