For my next project, I decided to create my version of a popular robot project: the hexapod walker. This Raspberry Pi-powered robot will have an autonomous mode where it runs by itself and avoids obstacles and a manual mode where it can be controlled by a smart phone. Interested? Here’s how I did it. There are lots of ways to use this gait in a hexapod walker. I chose to build a three-servo motor version which I found to have a balance between price and performance. Then I added another servo motor where the “eyes” of the robot are mounted. The robot will have three movements: forward, backward, turn right, and turn left. Any movement always involves tilting the robot to the right or left and then moving the leg that is lifted by the tilt. Below are the diagrams for the movements (a gray on a leg means the weight of the robot is on that leg).”
