End-Effector for Robots

This technology is a paddle-type end-effector designed to lift injured persons or objects from the ground. An elastic element mounted at the end of the paddle member physically deforms upon contact with the object; this deformation toggles a switch to detect the insertion state. Additionally, a hinged bracket provides a compliance function to prevent collisions with the object.

Conventional robotic end-effectors are often too thick, making it difficult to insert them between an injured person and the ground. This poses a risk of secondary injury during insertion, while exposed cables lead to durability issues and a lack of reliability in autonomous robotic rescue operations.

This technology features an insertion-sensing unit composed of an elastic element and a switch at the tip of a thin paddle member, which deforms under external force from the object. It also utilizes a compliance structure that connects the paddle to the robot body via a hinged bracket, allowing for angular adjustments that mitigate impact upon contact. Applicable to logistics picking, service robots, and manufacturing automation, it prevents damage and ensures safe insertion of the paddle, thereby enhancing the safety and effectiveness of rescue operations.

Key Features:

• An end-effector for robots where a switch element turns on when the elastic element is deformed and turns off when the elastic element returns to its original state.
• A sensing unit provided on the paddle member to detect whether the paddle member is fully inserted.
• A paddle member mounted to the robot body, designed to be inserted between the object to be transported and the surface.
• The sensing unit is positioned adjacent to the end opposite to where the paddle member is attached to the robot body, and the sensing unit includes an elastic element that deforms under external force applied by the object being transported.
