ROS Software Maintainer: qbrobotics®
qb SoftHand is an adaptable yet robust robotic hand gripper for collaborative robotic arms and for humanoid robots. It is in scale 1:1 with the average human hand and it is similarily composed by 19 completely desensorized phalanges and a flat palm.
The specific system of tendons connected to just a single motor provides the mechanical adaptability of the grasp to the shape and softness of any object without damaging it, i.e. exploiting the intrinsic capability of soft robots to continuously deform in a huge variety of possible configurations through interaction with external items.
In addition, the single actuator fixed directly on the back of the hand barely affects the total encumbrance and weight (only 480 grams) of the device.
