Welcome to The Turtle Challenge
Most of us make robots, and most of us make robots that can somehow manage to move around on a flat surface.
But.. Can you make a robot that can
Drive, crawl, walk, or jump around.. perhaps even avoid obstacles etc..
Lay upside down
If it is lays upside down, sideways, or in any position on a flat surface, will manage to turn itself around to "upright" and start moving again
letsmakerobots.com will mail 1 set of cool belt tracks with geared motors (chose gear ratio and color yourself) to the first robot builder who is building and submitting a robot that can do that.
