RBO Hand 3
The RBO Hand 3 is a highly capable anthropomorphic soft hand developed by TU Berlin's Robotics and Biology Lab, featuring pneumatic actuation for dexterous manipulation. It combines 16 independent degrees of actuation with intrinsic compliance via two-chambered fingers, an opposable thumb, actuated palm, and finger spreading. Designed for real-world experiments, it replicates human hand functions, achieves top Kapandji thumb opposition scores, supports all 33 GRASP taxonomy types, and enables in-hand manipulation.
