The Inspire EG2-4B is a compact parallel-jaw electric gripper from Inspire Robots. Although it is sometimes catalogued alongside dexterous-hand components, it is functionally a two-finger electric gripper: two opposing fingers translate along a straight line to pinch objects, driven through an innovative linear mechanical linkage that delivers a large 70 mm total stroke from a body weighing just 223 g. The servo drive and control electronics are integrated inside the unit, so no external valves, regulators, or drive boxes are required. Force and position are both closed-loop controlled, with a 0–15 N adjustable grip force range, ±1 N force repeatability, and ±0.50 mm positioning repeatability, while a built-in sensing concept supports threshold-based gripping of objects with different hardness. A defining safety-oriented feature is power-off self-locking, which helps retain a grasped object during brief power interruptions (depending on load, friction, and fingertip geometry).

In typical deployments the EG2-4B mounts at the end of a robotic arm or mobile manipulator and is controlled over an RS485 serial link — with MODBUS RTU support documented for the current “X2” generation — using parameterized commands for opening width, force limits, and status feedback. On power-up the gripper defaults to its maximum opening position, which simplifies initialization in scripted routines. Running from DC 24 V with a 0.70 A peak current, reaching speeds up to 97 mm/s and closing its full stroke in 0.85 s, it suits service robotics, education, research prototyping, and light automation — particularly benchtop cells and mobile platforms where compressed-air infrastructure is impractical. In its 15 N force class it is typically used for small parts, lightweight fixtures, and packaged items where repeatable pinch gripping matters more than high clamping force.
