John Park builds some lively and inexpensive miniature robots. Starting with a simple vibrabot made from a scrub brush, John assembles a solar junkbot and a slightly more complex beetlebot, which has paper clip feelers attached to switches that allow it to respond to its environment. All it takes are a few common electronic components and some everyday objects and you can make an entertaining robot all your own.
