Inventive project and write-up from instructables user CarlS. Thanks for sharing, Carl!

This is the latest version of the Bucket Bot – a mobile PC based robot that can be easily transported in a 5 gallon bucket. The previous one used simple wood based construction. This newer version is based on aluminum and T-Slot, so it is easily expandable.

The bucket bot concept is a vertically oriented robot where all the components are easily accessible. This is superior to the layered approach since you don’t need to unscrew layers to work on the lower level components. This design has the all-important features for mobile robots: a handle and motor power switch!

I also incorporated some new components that make the building easier. There is a little fabrication involved, but it can all be done using hand tools. You can also use a laser cutter for a plastic version of this robot, or use a metal cutting service like the Big Blue Saw if you would like with the included designs.
