Building a Rover to Carry a Robot Arm
Milos Rasic of element14 Presents recently built a pretty nifty robot arm of his own design using 3D-printed parts and affordable servo motors. That is useful when mounted to a desktop or workbench, but it would be even more useful if it could move around to reach different physical locations. To achieve that, Rasic constructed a kind of rover base that carries the robot arm.
In the world of robotics, one might refer to this as an AGV (automated guided vehicle). But at this stage, it isn’t autonomous and so I’m hesitant to use the term. Because it only looks like an AGV and operates under manual control, I’ll just call it a rover.
