Technological progress in integrated, low-power, CMOS communication devices and sensors makes a rich design space of networked sensors viable. They can be deeply embedded in the physical world and spread throughout our environment like smart dust. The missing elements are an overall system architecture and a methodology for systematic advance. To this end,(More)
We have demonstrated a family of large force and large displacement electrostatic linear inchworm motors that can operate with moderate to high voltages. The inchworm motor design decouples actuator force from total travel and allows the use of electrostatic gap-closing actuators to achieve large force and large displacement while consuming low power. A(More)
We have demonstrated an autonomous two-legged microrobot which has taken its first steps. The body of the robot is fabricated in a planarized silicon-on-insulator (SOI), two-layer polysilicon process and is 8.5 mm x 4 mm x 0.5 mm in size. We previously reported initial leg motion from an off-board controller but have now incorporated control and power(More)
A glove with 2-axis accelerometers on the finger tips and back of the hand has been built using commercial-off-the-shelf components. Taking advantage of gravity induced acceleration offsets, we have been able to identify pseudo static gestures. We have also developed software that allows the glove to be used as a mouse pointing device for a Windows 95 or NT(More)
With the ultimate goal of creating autonomous microrobots, we developed a five-mask process that combines two polysilicon structural layers with 50m-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 yields(More)
The paper mentions that the Engineering Entrepreneurs Program has been helping engineering students become entrepreneurs. What began as informal student meetings has grown to a three-course sequence with graduates who have pioneered successful companies. Assessments show a positive correlation between program participation and entrepreneurial action.

The market demand for a low-cost transportation system that operates efficiently in a circulatory environment is significant. In this paper, we propose a solution, EcoPRT, a two person, electric, autonomous, low cost, adaptable system that solves the circulatory problem, being ideal for areas that are too far to walk but too short to drive. The key(More)
