  1. A Hand Prototype Eduardo Torres-Jara CSAIL- MIT

  2. Prototype

  3. Approach • Sensor based instead of model based • Developing touch sensing instead of vision • Real contact with the world • Less risky for environment and robot itself because of compliance

  4. Hand Features • Force sensing at fingertips • High spatial resolution • Force sensing at joints • Mechanical compliance • Low impedance • Shock resistance

  5. Finger

  6. Tactile Sensors • Array of Force Sensing Resistors (FSR) • Resolution: 200 points per inch. • Report X, Y coordinates and force (7 bit res.)

  7. Actuator Small Rotary Elastic Actuator

  8. Decoupling for grasping

  9. Rotating Fingers

  10. Hardware Architecture • Force actuators controlled by DSP • Tactile sensors read by PICs • Integration by DSP56F807
