BEAM Vibrobots

The online Make magazine portal just published a nice article on how to make your very own BEAM vibrobots. For those of you unfamiliar with the BEAM movement, the basic notion is to wire up simple circuits that connect photo-sensors almost directly to motors, so that by shining a light on the simple robot, it will scurry around either towards, or away from, the light thereby mimicking any number of insects. And then, of course, there is all the fun and art in arranging the components to look as insectile as possible.

The Vibrobot takes this notion to a minimalist extreme by eliminating wheels, and reducing the number of motors to one tiny pager motor with an eccentric weight attached. When light shines on the photo-cell, the motor vibrates, and with proper sprung leg designs, the robot will scurry along in fine insect fashion. And without the wheels, the vibrobots are ever more insect like in form as well.

Here’s a page from the no-doubt forthcoming print edition showing the simple circuit used for these nifty little critters…
