movej
Control robot joint movements by sending precise angle, speed, acceleration, and timing parameters to Universal Robots through the nUR MCP Server.
Instructions
发送新的关节姿态到指定IP的机器人，使每个关节都旋转至指定弧度。 IP：机器人地址， q：各关节角度， a：加速度（米每平方秒）， v：速度（米每秒）， t：移动时长（秒）， r：交融半径（米）。

Implementation Reference
- The MCP tool handler for 'movej'. Decorated with @mcp.tool(), it handles the tool execution by linking to the robot, sending the movej command via the UR library, and confirming success using movejConfirm.
