The invention discloses a collision detection system for evaluating obstacle recognition capability of an intelligent mobile robot, which comprises a bottom plate, guardrails, a base frame, a simulation obstacle, a rigid structure cylinder, a force sensor and a camera, and is characterized in that the bottom plate is provided with two parallel guardrails to form a test area; the front part of the test area is provided with a starting test point of a tested robot, the rear part of the test area is provided with the base frame and the simulation obstacle, and is provided with an avoiding outlet, the simulation obstacle is provided with a guide rail groove for installing the force sensor, and the force sensor is arranged in the guide rail groove. The rigid structure cylinder is fixedly connected to the front of the force sensor and serves as a collision contact object with a detected robot, the camera is arranged over the rigid structure cylinder, and the camera is installed on the base frame. According to the invention, omnibearing robot obstacle avoidance capability testing can be realized.

The invention discloses a curtain wall force transmission system and a construction method thereof. The force transmission system comprises a building body and a reserved window opening, a curtain wall keel is fixed to the building body, a curtain wall plate is fixed to the curtain wall keel, a window opening auxiliary frame is fixed in the reserved window opening, an adjustable supporting piece is arranged between the bottom of the window opening auxiliary frame and the reserved window opening, and a force transmission rod is connected between the curtain wall keel and the window opening auxiliary frame. The construction method comprises the following steps: fixing a curtain wall keel on a building main body; an adjustable supporting piece is arranged at the bottom of the reserved window opening of the building body; a window opening auxiliary frame is temporarily positioned and installed in the reserved window opening; the adjustable supporting piece is supported between the bottom of the window opening auxiliary frame and the reserved window opening. A dowel bar is connected between the curtain wall keel and the window opening auxiliary frame; a curtain wall wallboard is installed on the curtain wall keel; a window body is installed on the inner side of the window opening auxiliary frame. The building curtain wall has the beneficial effects that force on the curtain wall glass, the curtain wall keel and the curtain wall plate is effectively transmitted to a building main body structure, and the structural safety of the building curtain wall is improved.

This utility model relates to the field of medical devices, specifically a reverse separation forceps, comprising the following components: a positioning post one, which is fitted onto the forceps handle; a forceps handle, on which two symmetrical posts are provided; a forceps bar, which is mounted on the forceps handle, and a forceps arm is provided between the forceps handle and the forceps bar; a forceps arm, on which a second positioning post is provided; a forceps tip, which is located at the end of the forceps bar. The forceps arm connects the forceps handle and the forceps bar, acting as a lever to provide external force when muscle tissue needs to be separated; the forceps arm has positioning posts for controlling the accuracy of the left and right forceps bar alignment and limiting the pinching position, while also acting as a rocker arm to ensure precise contact and separation of the forceps tip, thus improving the accuracy of grasping muscle tissue during surgery and the separation force required to separate the muscle tissue.
