While waiting for parts to come in for SAGAR, I decided I’d kill three birds with one stone. I wanted to adapt my Irobot command code to be compatible with Webbot’s Lib, I wanted to test Webbot’s new Project designer, and I wanted to try out a Force Field Obstacle Avoidance Algorithm. This is what I came up with.
It’s an Irobot Create, controlled by an Axon 2 running Webbot’s Lib, a Sharp IR and a standard servo. Theoretically, obstacles in front of the robot will ‘repel’ it while free space ‘attracts’ it. The closer and more directly in the way an obstacle is, the more it ‘repels’ it away.
