Implementation Reference
- The core handler function for the 'connect_ur' MCP tool. It establishes a connection to a Universal Robots (UR) robot using the URBasic library, initializes the robot model and script extension, verifies RTDE connection and remote control mode, and manages global robot_list and robotModle_list dictionaries.@mcp.tool() def connect_ur(ip: str): """根据用户提供的IP连接UR IP：机器人地址""" try: host = ip global robot_list, robotModle_list if robot_list.get(ip, "unknown") != "unknown": robot_list[ip].robotConnector.close() return return_msg(f"优傲机器人连接失败: {ip}") robotModle = URBasic.robotModel.RobotModel() robot = URBasic.urScriptExt.UrScriptExt(host=host, robotModel=robotModle) robot_list[ip] = robot robotModle_list[ip] = robotModle if robot_list.get(ip, "unknown") == "unknown" or not robot_list[ ip].robotConnector.RTDE.isRunning(): return return_msg(f"优傲机器人连接失败: {ip}") robot_list[ip].robotConnector.DashboardClient.ur_is_remote_control() remote = robot_list[ip].robotConnector.DashboardClient.last_respond.lower() print(f"remote:{remote}") if remote != 'true' and not remote.startswith('could not understand'): disconnect_ur(ip) return return_msg(f"请检查机器人是否处于远程控制模式。IP:{host}") return return_msg(f"连接成功。IP:{host}") except Exception as e: logger.error(f"优傲机器人连接失败: {str(e)}") return return_msg(f"优傲机器人连接失败: {str(e)}")
- src/nonead_universal_robots_mcp/server.py:147-147 (registration)The @mcp.tool() decorator registers the connect_ur function as an MCP tool.@mcp.tool()
