The CotsBots are inexpensive and modular mobile robots built entirely from commercial off-the-shelf components. These robots provide a convenient platform on which to investigate algorithms, cooperation, and distributed sensing in large (> 50) robot networks. Each robot is small (13cm x 6.5cm base) and costs under $200. Each is equipped with on-board(More)

An elastomer-based energy storage system for MEMS has been designed, built, and tested. Micro rubber bands have been fabricated from silicone using two different methods, laser-cut and molded, and assembled into silicon microstructures fabricated in a two-mask silicon-on-insulator (SOI) process. Using silicon hooks and force gauges designed in this process,(More)
—With the ultimate goal of creating autonomous mi-crorobots, we developed a five-mask process that combines two polysilicon structural layers with 50-m-thick SOI structures and a backside substrate etch. The polysilicon layers provide three-dimensional (3-D) hinged structures, high compliance structures , and electrical wiring. The SOI structural layer(More)
