Solar-powered junkbot

solar_powered_junkbot

Instructables user [martzsam] recently built a simple robot using miscellaneous junk he found around his house. The first parts he scrounged up were a pair of 1.5v electric motors and some wire scraps, after which, he went to work on an old garden light. He detailed how to carefully remove the light’s solar panel as well as the charging circuit, which he used to power his robot. The pieces were mounted on some old erector set parts after a bit of rewiring, then the bot was set in motion. [martzsam] also mentions that he tweaked the solar panel’s charging circuit and battery to run the motors at half speed until light is shone on the panel, at which point the robot runs at full speed.

This project would be great to do with kids as it teaches the concepts of re-purposing common household items as well as allows them to use their imagination in designing a fun, yet simple robot. Gather up some old junk and your kids/nieces/nephews and get going!

    lets give it some eyes and a brain and this will be a very nice hack..
    Although I must say he gave me an idea of what to do with those old malfunctioning garden lights the last owner left behind

    damn i was thinking that is a big heavy solar junkbot, i have a solar panel that size. but then i saw the yellow things, and the scaling shrank down to about 2000 times it’s size.

    I have the solar panel from a solar birdbath that might get put to use in a junk bot.

    Food for thought, -THANKS!
