Making a robot walk instead of drive around on wheels can be a daunting task. The author of this Walking Bug came up with a remarkably simple solution. Although our robot does not stand upright on two legs, it can actually walk using just two servos and a minimumamount of electronics. The power of the design is, of course, found in the combination of these two elements. The servos make the ‘natural’ movement needed here: just back and forth. As an advantage over other actuators, they can be directly driven by a microcontroller, which saves us a lot of driver and interfacing electronics. The mechanical construction of the Walking Bug is also relatively simple, the ‘legs’ being secured directly to the servo spindles.
