A holding system includes a force control module configured to generate a force signal to cause a holding device to perform at least one of a hold stroke and a release stroke. The hold stroke includes transitioning a gripping element of the holding device to a first position to grip an object. The release stroke includes transitioning the gripping element to a second position to release the object. The holding device is non-backdrivable. A stall detection module is configured to (i) monitor a sensor signal received from a sensor of an electric motor assembly of the holding device and (ii) detect a first stall condition of an electric motor based on the sensor signal. A shut off module is configured to shut off current to the electric motor based on the detection of the first stall condition during or at an end of the release stroke.

Electric motor based holding control systems and methods

A suction cup assembly has a housing with an actuator in the housing. A flexible cup is coupled with the housing. The actuator movement causes the flexible cup to move between at least two positions. In a first position, the flexible cup moves into an increased volume position. In a second position, the flexible cup moves into at least a neutral volume position. In the increased volume position, the flexible cup seals with a surface. In the neutral volume position, the flexible cup releases from the surface.
