31313 Port3r




This walking robot was inspired by a water sculpture I saw in Basel, Switzerland. I was looking for a way to create a walking robot that wasn't encumbered by the weight of the brick. I toyed with the idea of disguising the brick as a shopping trolley or pram complete with baby. On a hard surface this has a really nice glide.

The build went through about 5 or 6 versions to get to the final model. Once I had it reliably walking I switched from a right angle between the brick and handle to the configuration shown. It is quite sensitive to the choice of wheels for it to work.

This is a C-model using only the parts from 31313 Mindstorms EV3.
