Personal protective equipment

Proper safety equipment worn to maintain safety and protect both components from damage and individuals from harm depending upon the hazards involved (e.g., safety glasses, gloves, hearing protection).

Eye protection

Safety glasses or goggles that help protect eyes from harmful materials such as particles, sparks, or chemicals.

Hand protection

Gloves typically made of rubber, leather, or anti-static materials that protect hands from heat, cuts (sharp edges), or electrical shock.

Hearing protection

Earplugs or earmuffs meant to reduce noise levels that can hurt hearing.

Respiratory protection

Masks or respirators that filter dust, fumes, or harmful gases from the air.

Footwear

Safety shoes or boots that are either slip-resistant or have steel toes to protect feet from heavy or sharp items, heavy tools, falling robot parts, or slippery floors.

Body protection

Sturdy clothing or lab coats made of heat-resistant or nonconductive material to protect against burns, cuts, chemical exposure, and clothing binding to equipment.

face shields

A see-through plastic guard that protects the whole face, serving as an added layer of protection during cutting, grinding, or machining operations.

5S method

An abbreviation of Japanese origin, initially developed as a workplace organization method in manufacturing, engineering, and robotics to attain accuracy, efficiency, safety, and productivity in daily task execution

Safety symbols

Visual representations using a combination of illustrations and colors with specific meanings to identify hazards (e.g., Cross/First Aid, Danger Keep Out, Danger Do Not Enter, Warning, Caution, Crush Zone).

ventilation

Having a properly ventilated space for soldering to avoid inhaling harmful fumes produced when joining delicate connections in robotic circuits.

powering down before adjustments

Turning off a device's power prior to making any connections or adjustments to avoid short circuits, prevent electrical shock, and avoid damaging components.

Electrostatic discharge protection

(ESD) Properly handling electronic components to avoid static electricity discharge that can damage sensitive microcontrollers and sensors.

Battery and power supply safety

Taking extra precautions when handling batteries and power supplies commonly used in robotics because they can overheat or explode.

Insulated tools

Using insulated tools when working with live circuits to reduce the risk of electrical shock

Double checking connections

Making a habit of double-checking wiring connections before powering up a circuit to prevent damaging components in robotic systems.

Voltage

V): The difference in electric potential between any two points in a circuit; referred to as the "Electrical Push" that pushes electric charges through a circuit.

Current

(I): The flow of electric charges (electrons) through a circuit

Resistance

(R): The opposition to the flow of electric current, controlling or slowing down the number of electrons that get through a circuit.

Ohm’s law

The principle describing the relationship between voltage, current, and resistance in an electrical circuit, stating that the amount of current ($I$) is directly proportional to voltage ($V$) and inversely proportional to resistance ($R$)

Autonomous systems

Systems powered by small processors (microcontrollers) that sense what is happening, decide what to do, and act on their own (e.g., automatic doors, automated traffic lights)

Microcontroller

Compact integrated circuits that serve as the "brain" of a device; they receive signals from input sensors, process information, and send output signals to components like motors or lights.

Arduino UNO

An open-source electronic platform containing a small board with all necessary components to read inputs and control outputs; popular for beginners and experts due to its flexibility and easy programming environment

Microcontroller

(ATmega328P): The brain of the Arduino board; executes uploaded code from a computer and controls other components accordingly

digital input/output pins

(0–13): Pins that can be configured as either input or output pins for digital signals

Analog input pins

(A0–A5): Pins that read analog signals from sensors (e.g., light sensors, temperature sensors)

Power pins

Pins containing 3.3V, 5V, GND (Ground), and Vin to provide or receive power from devices or other microcontrollers.

USB port

Used to upload code from a computer to the board and power the board.

Power jack

Allows powering the Arduino board with an external power adapter or battery

Reset button

Restarts the microcontroller and restarts the uploaded program from the beginning during boot-up without needing to re-upload the code.

Voltage regulator

: Regulates incoming voltage so the board can function properly without damage

Crystal oscillator

Keeps track of timing (integer for timing) for scheduled events, such as blinking an LED at a certain interval.

TX/RX leds

Transmit (TX) and Receive (RX) LEDs that display data being sent or received through the USB cord; highly useful for debugging communication.

ICSP header

Allows direct programming of the microcontroller or communication with other devices using Serial Peripheral Interface (SPI).
