Microrobot Developed at Dartmouth

TheSync writes "Dartmouth researchers have developed the world's smallest untethered, controllable microrobot. The microrobot is much smaller and less massive than previous controllable microrobots. It measures only 60 by 250 micrometers. It receives power and control signals from the grid of electrodes it walks on, and moves by bending its body like a caterpillar. Not quite nanomachines, but we are getting closer!"

Ah, proof-reading

"Smaller and less massive"? Are they also more effective and less ineffective than previous designs?
