The compact RM-EGB Series grippers from RobustMotion operate by sliding a pair of fingers together or apart laterally to grip and release. These fingers, which are designed to serve as mounting points for customized (e.g. 3D-printed) extensions, are able to exert consistent force in both directions, allowing them to grab parts internally (by opening into a gap) or externally (by clamping down) with missed pickup and dropped part detection.

These grippers are available in two different sizes and each size is available with or without an RS-485 interface (see comparison table below). They fit small collaborative robots (cobots) such as the Dobot MG400, and operate at 24 VDC, which can be supplied from the MG400. The simple PNP-type PLC interface can connect directly to the MG400 I/O ports. A simple 3D-printed adapter (139k STEP) can be used to mount a gripper to the MG400 arm.

Details for item #5406
This is the larger of the two available gripper sizes, with a max stroke of 10 mm (both fingers combined) and a maximum gripping force of 80 N. It supports Modbus RTU over RS-485 (in addition to the PNP-type PLC interface).
The gripper can cover its full 10 mm stroke length in under 0.18 s. In addition to the fully open and fully closed extremes, the simple PNP-type PLC interface offers two preset intermediate positions (at 4 mm and 8 mm) that are achievable with ±0.02 mm repeatability, and the grip strength can be controlled by selecting from four preset force levels up to 80 N. The RS-485 interface gives more precise control of the position (0% to 100%) and force (25% to 100%). See the RM-EGB user’s manual (2MB pdf) for more information.
