  • Patent number: 11318603
    Abstract: A delta robot includes a robot base, an end effector carrier that can be positioned in space, and three parallelogram articulated couplings which connect the end effector carrier to the robot base and are designed to connect the end effector carrier in a displaceable manner while maintaining its orientation in space relative to the robot base. Each parallelogram articulated coupling can be displaced, driven by a motor, to automatically move the end effector carrier, wherein each motor can be braked by means of a brake in order to automatically stop the end effector carrier and/or to hold the end effector carrier in its present position. The end effector carrier comprises at least one input device connected to the brakes by control technology and designed to release the brakes in an actuated switching state of the input device such that the end effector carrier is manually displaceable.

  • Patent number: 11261964
    Abstract: A multi-directional compliant shifting mechanism for a multi-speed power tool may couple a movable selector to a power transmission system of the tool, for selecting an operational speed of the multi-speed power tool. The complaint shifting mechanism may provide shifting compliance in a first direction in response to movement of the selector in a first direction, and may provide shifting compliance in a second direction in response to movement of the selector in a second direction. In one example, this multi-directional shifting compliance may be provided by interaction of the selector with a camming surface, in combination with a single compression spring. In another example, this multi-directional shifting compliance may be provided by first and second springs, selectively acting to provide compliance in the first and second directions.
