BionicSoftHand Highly integrated soft robotic components Unlike the human hand, the BionicSoftHand has no bones. It controls its movements via the pneumatic structures in its gripper fingers. When the chambers are filled with air, the gripper fingers bend. If the air chambers have been exhausted, the gripper fingers remain stretched. The thumb and index finger are additionally equipped with a swivel module which allows these two gripper fingers to be moved laterally. This gives the bionic robot hand a total of twelve de- grees of freedom. Two pneumatic swivel modules One additional degree of freedom for each lateral movement Three tactile force sensors For measuring force and detecting different gripping objects Elastomer bellows With two air chambers for moving the gripper fingers Flexible printed circuit board With meander structure and integrated inertial and force sensors Inertial sensor system Reference point for the inertial sensors in the gripper fingers for position recognition Motherboard For controlling the hand Airflow plate with integrated pressure sensors For connecting the valves with the tubing of the gripper fingers Two inertial sensors For recording the position of the gripper fingers 3D textile knitted fabric Woven structure with elastic and high-strength synthetic fibres Elastic silicone skin For improving the haptics and protecting the sensors Compact valve terminal With 24 proportional piezo valves for precisely venti- lating and exhausting the gripper fingers and control- ling the swivel modules
