  1. DARPA DARPA MTO MEMS SMART DUST K. Pister, J. Kahn, B. Boser (UCB) S. Morris (MLB)

  2. Goals • Autonomous sensor node (mote) in 1 mm3 • MAV delivery • Thousands of motes • Many interrogators • Demonstrate useful/complex integration in 1 mm3

  3. COTS Dust GOALS: • Create a network of sensors • Explore system design issues • Provide a platform to test Dust components • Use off the shelf components

  4. N W E S 2 Axis Magnetic Sensor 2 Axis Accelerometer Light Intensity Sensor Humidity Sensor Pressure Sensor Temperature Sensor COTS Dust - RF Motes • Atmel Microprocessor • RF Monolithics transceiver • 916MHz, ~20m range, 4800 bps • 1 week fully active, 2 yr @1%

  5. COTS Dust - Optical Motes Laser mote • 650nm laser pointer • 2 day life full duty CCR mote • 4 corner cubes • 40% hemisphere

  6. Video Semaphore Decoding Diverged beam @ 5.2 km In shadow in evening sun Diverged beam @ 300m Shadow or full sunlight

  7. ’01 Goal

  8. Micro Mote - First Attempt

  9. AR coated dome lens Steering Mirror laser CMOS ASIC 2D beam scanning

  10. Delivery by MAV Built by Steve Morris, MLB Co. • 60 mph • 18 minutes • 1 mile comm.

  11. Micro Flying Insect • ONR MURI/ DARPA funded • year 1 of 5 year project • Dickinson, Fearing (PI), Liepmann, Majumdar, Pister, Sands, Sastry • Heavily leveraged on Smart Dust

  12. Conclusion • Wireless sensor networks • COTS! • MEMS-enabled • Optical comm • 20 km from a cubic inch • size limits: ~1mm3 • Applications • stockpile monitoring: from small arms to W88 • transparent battlefield: from desert to MOUT • chem/bio • virtual keyboard
