Don’t let NASA monopolize robotic exploration of the solar system. Using a couple of gear motors, solar panels, and leftover LEGOs, you can build a sunshine-powered robot that ambles around a strange landscape: your backyard. Obstacles such as rocks and curious children can’t be avoided, since there’s no software or sensors to control the steering, but this project is a fun introduction to solar-powered electronics.
Materials:
- Two gear motors
- Two solar panels
- Assorted LEGO pieces
- Cyanoacrylate glue
- Hookup wire
Tools:
- Soldering iron
- Wire cutter
