Quadruped TrotBot

Picture

As can be seen in the following video, Quadruped TrotBot uses the same building instructions as Hexapod TrotBot, but with a pair of legs and a frame side removed.

The above quadruped could barely walk on the carpeting at the end of the video due to how much it rocked back and forth, which caused its rear feet to drag.  This is mitigated below by attaching some gears to the outside of the feet, which help to keep the legs vertical, reducing rocking and foot-dragging.​


​
Below are a few more details of this build.  You can find leg instructions here, and the frame instructions here where you will want to build Hexapod TrotBot's main frame with the gear train.
