Robot Safety Rules
Six workshop habits that keep robotics safe

Robots can move fast, pinch fingers, spin wheels, cut materials, and carry electrical power, so safety rules protect both people and equipment. In a robotics lab, most injuries happen when students rush, reach into moving parts, or change wiring while power is on. Clear routines make building and testing more predictable for everyone. Good safety habits let teams focus on design, problem solving, and learning.
Key Facts
- Wear safety glasses whenever cutting, drilling, sanding, hammering, or working near flying debris.
- Tie back long hair, tuck in loose clothing, and remove dangling jewelry before working near motors, belts, gears, or wheels.
- Keep fingers, tools, and wires away from moving parts because rotating parts can pinch, pull, or cut.
- Press the emergency stop if a robot moves unexpectedly, makes unusual noise, smokes, sparks, or heads toward people.
- Power off and disconnect the battery before wiring, changing parts, or reaching inside the robot. P = VI describes electrical power.
- Test robots in a clear marked area away from people because force depends on mass and acceleration: F = ma.
Vocabulary
- Emergency stop
- A button or switch that quickly cuts power or disables motion when something unsafe happens.
- Pinch point
- A place where moving parts can trap or squeeze fingers, clothing, wires, or tools.
- Personal protective equipment
- Safety gear such as goggles, gloves, or closed toe shoes used to reduce the chance of injury.
- Power disconnect
- A switch, plug, or battery connection that removes electrical power from a robot before work begins.
- Test zone
- A marked clear area where a robot can be operated while people stand a safe distance away.
Common Mistakes to Avoid
- Wearing safety glasses on your forehead instead of over your eyes is wrong because debris can hit your eyes before you have time to react.
- Changing wires while the battery is connected is wrong because an accidental short circuit or motor start can damage parts or injure someone.
- Holding a robot in your hands during a motor test is wrong because wheels, arms, or gears can move suddenly and pinch or pull skin and clothing.
- Testing a robot in a crowded aisle is wrong because unexpected motion can hit people, trip someone, or damage tools and projects.
Practice Questions
- 1 A robot uses a 12 V battery and draws 4 A while driving. What electrical power is it using? Use P = VI.
- 2 A 5 kg robot accelerates at 2 m/s^2 during a test. What net force is acting on it? Use F = ma.
- 3 Your team needs to replace a loose wire near a motor, but the robot is still powered on and a teammate says it will only take a second. What should you do first, and why?
