Forum user solderspot recently posted on our forum about some modifications he’s been making to his Zumo robot. First, he added our optical encoders for micro metal gearmotors to his robot, which required using motors with extended back shafts and cutting holes in the chassis to route the wires from the encoders.
This allows his Zumo to navigate by dead reckoning, using just the information from the encoders.
He also mounted a sonar sensor on a servo to his robot, which enables it to find its way around a room by following the walls.
A series of articles on solderspot’s blog, starting with this one, covers his experience building and programming his robot. It looks like solderspot has further plans for the Zumo, including more sophisticated autonomous navigation, so watch his blog if you want to keep up with the latest developments.
