March of the microscopic robots

Building robots at the micron scale is tricky, particularly when it comes to designing small-scale โ€˜actuatorsโ€™ โ€“ the motors that allow robots to move. Conventional actuators donโ€™t work at such a small scale, and new actuators that do work use mechanisms like magnetism and are difficult to integrate with traditional silicon based micro-electronics. Now a […]
