Schunk has optimised its five-finger hand concept so the motor controllers on the hand are now integrated into the wrist to make the anthropomorphic gripper hand far more compact.
Working with defined interfaces, the Schunk gripper hand can be connected to the Schunk six-axis lightweight robotic arm, which is already available to purchase. For mobile applications, the energy supply of the five-finger hand requires a battery-servable 24V DC. This differs to the first concept version of the hand that was controlled via a serial Bus, providing increased flexibility.
The Schunk gripper hand has also now been developed into left- and right-hand versions. The size, shape, mobility and overall aesthetics of the hand closely resemble the human hand. By utilising nine drives, the five fingers can carry out various gripping operations and motions. Moreover, numerous gestures can be constituted, which simplifies the visual communication between a human and a service robot. This makes acceptance for applications in the human environment more practical and likely.
Using tactile sensors in the fingers will grant the necessary sensitivity of the gripper hand for mastering gripping and manipulation tasks. This will be particularly prominent in unstructured and unforeseeable environments. The new hand also incorporates elastomeric gripping surfaces to ensure a reliable grasp of gripped objects.
