A passive universal gripper includes a mass of granular material encased in an elastic membrane. Using a combination of positive and negative pressure, the gripper can rapidly grip and release a wide range of objects that are typically challenging for conventional universal grippers, such as flat objects, soft objects, or objects with complex geometries. The gripper passively conforms to the shape of a target object, then vacuum-hardens to grip it rigidly; later using positive pressure to reverse this transition-releasing the object and returning to a deformable state. The apparatus and method enable the fast ejection of objects from the gripper, as well as essentially instantaneous reset time between releasing and gripping.

The method of this invention, and the apparatus which implements it, provides a way of sampling points on the surface of a portion of a rigid or semi-rigid object, which might be an anatomical body. Points are sampled by a moveable contact probe which emits a sonic waveform under the direction of a control unit. Multiple fixed sonic transducers in contact with the object at diverse locations detect the waveform, the arrival of which is timed for each transducer by the control unit. Given the speed of sound in the object and the coordinates of the transducers, a digital computer can compute the location of the probe. Two ways are presented to calibrate the locations of the transducers. Provision is made for mitigating possible distortion of soft object surfaces due to the contact force of the probe.
