This robot can be built up as a spinner, wedge, lifter, flipper, hammersaw etc.
It's designed to fit near any wheel available, from 20mm to 46mm in diameter, and can run with a range of electronics from Malenki's to standard Toy-Grade RC gear. 
Sized for N10 and N20 Motors, 9g-sized servo and 1806 Spinner motors, though it should be fairly tolerant of a range of parts. 


Parts for Wedge currently included, more to come once the other configurations have been tested.
