Tactile SoftHand-A
The Tactile SoftHand-A is a 3D-printed, highly underactuated, five-finger anthropomorphic robot hand developed by researchers from University of Pisa and IIT, inspired by the Pisa/IIT SoftHand. It features 15 degrees of freedom actuated by 2 motors via an antagonistic dual-tendon mechanism, enabling adaptive grasping. Integrated optical or piezoresistive tactile sensors in fingertips provide real-time force, pose estimation, and slip resistance, supporting compliant manipulation, teleoperation, and in-hand dexterity with a 7.5:1 underactuation ratio.

Frequently Asked Questions
Get answers to common questions about this robot
Q1. What is the humanoid robot hand Tactile SoftHand-A, and what problem does it solve?
Tactile SoftHand-A is a 3D-printed, highly underactuated, five-finger robotic hand developed by researchers at University of Pisa and IIT, inspired by the Pisa/IIT SoftHand. It addresses challenges in creating low-cost, adaptable grasping mechanisms for objects of varying shapes using minimal actuators and integrated tactile sensing.
Q2. What are the main capabilities and key features of Tactile SoftHand-A?
The hand features 15 degrees of freedom controlled by two actuators via a dual-tendon antagonistic mechanism, fully 3D-printed tactile sensors in fingertips, and adaptive grasping that adjusts to contact and slippage. According to University of Pisa and IIT, it enables human-hand-guided tactile feedback for compliant manipulation.
