Before connecting the real robot
Check the physical work area and power yourself, independently of the screen status. A software emergency stop does not replace an independent, safety-rated hardware protection device. Prepare a physical power cutoff.
Do not enable torque while a person is within the motion range. Joints and the gripper can move without warning. Keep fingers, hair, clothing, tools, and cables out of the motion path.
Before use
- Secure the base board to a flat, rigid workbench.
- Check voltage, current, polarity, and connector details on the product and adapter labels.
- Route motor power and USB cables outside the joint motion range.
- Keep the physical power cutoff within the operator's immediate reach.
- A teacher or safety observer must supervise student use.
When enabling or disabling torque
- Support the arm. The arm can fall under gravity when torque is off.
- Check the screen status. Check connection, calibration, and emergency-stop warnings.
- Look at the work area again. Directly confirm that people and obstacles are clear.
- Turn torque off after work. A normal Stop button can leave torque on. Support the arm and verify that it actually relaxes.
Stop immediately in these cases
| Situation | Action |
|---|---|
| Unexpected motion | Emergency stop, then physical power cutoff |
| Connection lost or state unknown | Do not approach the arm; cut physical power |
| Overheating, smoke, smell, or unusual noise | Immediately cut power and stop using the equipment |
| Collision or binding | Do not repeat the motion; inspect the mechanical condition |
Do not judge torque release from the screen alone. If the state is uncertain, cut physical power before approaching the robot. Record the condition for troubleshooting. Do not try to solve collision, overheating, or unknown torque state by repeated retries.
