This section will provide an overview of some of the safety concerns associated with the VEX Robotics Design System, but this is not an all-inclusive list

Pinch Points – Whenever an object moves, it has the potential of creating a pinch point. A pinch point is when two surfaces pass by one another close enough to “pinch” something. These occur where gears, sprockets, drive chains, drive shafts, wheels, tracks, turn tables, robot arms, and any other possible thing that can be made to move and come together. The small size of the VEX system makes it appear not to be dangerous, but the mechanical advantages achieved by the system can severely damage human tissue if it is placed in a pinch point. Long hair, loose clothing, long jewelry, neckties and other things which can hang in your work area can be caught in pinch points so they need to be restrained out of the work area. In addition, it is extremely important to keep all electrical wires and sensor wires away from pinch points. Pinch points can easily cut through the insulation on the wires causing a short circuit and can be EXTREMELY dangerous.

Sharp edges – Whenever a piece of metal or plastic is cut a sharp edge is created. These sharp edges should be filed or sanded to make them safe.

Eye Protection – Safety glasses should be worn whenever material is being cut or hammered, they also should be worn when operating the robot.

Autonomous operation – Whenever a robot has an autonomous program loaded in its controller, its wheels should be blocked up and hands should be kept away from the robot when it is being turned on. A robot which drives off of a table can be a dangerous situation.

Battery safety – Robot batteries need to be securely attached to your robot. Batteries should be unplugged by holding onto the plastic terminal block and NOT by pulling on the wires, the V5 batteries have a clip which locks the cable in place and must be released.. Any battery that has had a wire pulled off needs to be discarded at a battery recycle station.

Electrical wire – Any device with an electrical wire (motor wires, extension wires, servo wires, battery wires, programming wires, or sensor wires) that has a break in the insulating material, the device/wire should be discarded or if possible cover the exposed wire with electrical tape.

SAFETY is EVERYONE'S responsibility!
PLEASE watch out for each other!
