| The Nano Rover is an autonomous vehicle that uses two wristwatch motors as its main actuators. Analog wristwatch motors are one-phase Lavet stepper motors and are driven by a biphase pulse for every step. Small actuators are hard to get, most micromotors are too big for very small scale - aka tabletop - robots and consume too much power. The wristwatch motors are a nice trade-off between cost and performance. The only drawback is that they can only turn clockwise. There are wristwatch motors that can turn in both directions, but these are very hard to find. The design of the robot is build around this limitation of clockwise turning. The movement pattern of this robot is worm-like, in which each motor runs after each other and let the robot crawl around. |
