Curious about the claims on that patent. Robotics is already hard enough, I'm sure it will become easier with people suing each other because "you copied my wheeled robot with an arm attached to it!".
If your robot doesn't have these specific design choices, plus some others, it's not in violation. * Have a unibody base * Have an arm that is raised and lowered along a trapezoidal rail by a belt-driven linear actuator * Have a fisheye camera mounted on the center pole

Anyway, a base that looks like a Roomba, with a pole and an arm attached to it doesn't strike me as novel.
