A Fabrication Free, 3D Printed, Multi-Material, Self-Sensing Soft Actuator T Hainsworth, L Smith, S Alexander, R MacCurdy IEEE Robotics and Automation Letters 5 (3), 4118-4125

Highlights

  • An entirely print-in-place actuator with integrated sensor
  • A comparison of the actuator’s performance compared to past work (Figure 3)
  • A FEA comparison to traditional work (Figure 4)
  • Detailed print profiles (Table II)
  • Analysis of actuator and sensor’s performance and sensitivity (Figure 8 - 11)

Complex Design

The highlighted complex design would be difficult to manufacture with traditional methods, but is easy to make with additive manufacturing.

Comparing with Previous Work

The design design nicely balances blocked force with maximum deflection.

Sensor Analysis






The sensor can not only detect bending, but can also sense contact.
