When I saw the article from Instructables about this tiny robot, I knew that it was worth a post on RobotNext. At .40"x.50"x.46", the Magbot R-20 is slightly less than 1/20 of a cubic inch. The robot is magnetically controlled. This builder found out that to make the smallest robots possible, the motors, batteries, and even the Picaxe microcontroller had to be external to the robot. Even so, this little bot is a marvel. You have to see the video of this little machine picking up an IC that looks bigger than it is. This is not the first small robot built by this inventor. See his 1 inch cube bots to see a tiny machine with everything on-board. What is even more incredible is the fact that this is not the smallest robot he has constructed. Look at this link to see a robot that has a volume of only 1/100 cubic inch!
Build a 1/20 cubic inch robot with a gripper that can pick up and move small objects. It is controlled by a Picaxe microcontroller. At this point in time, I believe this may be the world's smallest wheeled robot with a gripper. That will no doubt change, tomorrow or next week, when someone builds so…
