Here is how it was made!
Overview
Component Breakdown
Electrical Breakdown
For the electrical design, the biggest step was converting 12V battery power to 5V for the Raspberry Pi and servo motors. Two voltage dividers were needed to allow signal capture while preventing pin damage. The rest of the electrical was connecting components so that the software team has everything they need to program the robot behavior. The schematic for the electrical design is below, and subsystem descriptions follow.
Mechanical Breakdown
There are two main components to the mechanical design: the legs and the chassis. We chose a four-bar linkage mechanism for the legs because it gave the tottering movement we wanted without being too complicated. The leg mechanism uses one continuous rotation servo for each side, giving a total of two.
