Small Sized Force / Torque Sensors for Robotic Arms and Hands

background

● Next generation robots need compact force sensors
● Sensors with digital output reduces necessary wiring
● No additional components for amplification and digitization required

summary

● Novel 6-axis F/T sensor based on capacitive ensing
● Novel 3-axis force sensors for distributed tactile sensing

predominance

● 6-axis sensor: 19x17x17 mm.
● Distributed sensor: 16 * 3-axis F/T in 20x23x3 mm.
  Flexible and soft. Only 3% hysteresis.
● Digital output. High signal-to-noise ratio.
● Temperature drift compensation

application/development

● 6-axis sensor: Force/torque feedback for manipulators.
  Deburring, polishing, grinding (where robot is required to apply a constant force).  
  Robotic part insertion. And many more…
● 3-axis sensor: Soft and sensitive cover for robotic arms.
