Let's make a desktop robot that moves. But wait, we have no tools.
It's been a while since I've done any robotics, so let's make that happen. When designing an autonomous system, it's critical to have clear objectives so that the requirements for end effectors, sensory inputs, and processing resources can be achieved inside your cost and time budgets. Instead of that, let's try to settle an office debate: what are the kinematics of a robotic platform positioned by 3 control rods?
Then, we'll put eyes on it. And it needs to fit on my desk; my apartment is not very large.
