DIY: Percevarence grass cutter

Introduction

Designed for slow motion (10 cm/s).

Theory

Rocker-bogie

https://en.wikipedia.org/wiki/Rocker-bogie

The tension, forces on the single joint?

Differential Joint

The two rockers connect to each other and to the body through a differential. It keeps the body level. When one rocker goes up, the other rocker goes down, and the body angle is halfway between the angles of the two rockers.
