Robotics is the art and science of designing, constructing, operating, and applying robots. It involves various fields such as electronics, computer science, mechanics, and artificial intelligence to create intelligent machines capable of performing tasks.

An embedded system is a microcontroller-based system designed for a specific task. It combines hardware and software to control devices like cars, appliances, or industrial machinery.

PCB Designing and Simulation involves creating the layout and circuit design of electronic components on a printed circuit board (PCB). Simulation software helps visualize and test the design before production.

Matlab Simulation refers to using MATLAB software to model and analyze complex systems. It involves writing code to simulate real-world scenarios and predict their behavior.

Aeromodelling is the hobby of designing, building, and flying aircraft models. It combines engineering principles, craftsmanship, and a passion for aviation.

Industrial training programs provide hands-on experience and practical skills in a specific field. They can involve working on real-world projects and learning from industry experts.

A project is a task or undertaking with a specific goal. It involves planning, execution, and evaluation to achieve a desired outcome.

The amount of rotational force a motor can produce, measured in kg-cm (kilogram-centimeter).

The speed at which a motor rotates, measured in RPM (revolutions per minute).

The relationship between torque and speed in a DC motor. Higher torque means lower speed and vice versa.

A motor designed to include gears, reducing the motor's speed while increasing its torque.

The ratio of input speed to output speed in a gearbox.

A type of motor that uses direct current (DC) electricity to produce rotational motion.

The amount of electrical current a motor draws, measured in mA (milliamperes).

The maximum voltage that can be applied to a motor without damaging it, measured in V (volts).

A type of motor that is not equipped with gears, resulting in higher speed but lower torque.

DC motors typically used in hobby robotics, available in 12V with 250mA current draw and speeds ranging around 2400 RPM.

An LED that emits infrared radiation, invisible to the human eye. It's commonly used in sensors and remote controls.

A specialized type of photodiode that is designed to detect infrared radiation.

A type of resistor with a carbon composite material as the resistive element. They are often used in high-frequency applications but can be susceptible to noise and stability problems when heated.

The generic term for resistors that use thin films of metal, carbon, or metal oxides as the resistive element. They are made by depositing a film onto a substrate and then cutting a spiral pattern into it.

The 38KHz IR transmission and reception is a widely used method for communication between IR sensors. It's often used in remote controls and other wireless devices.

Resistors made by winding a wire around a core. They are often used in high-power applications and offer good stability.

A device that focuses IR radiation, allowing us to see an otherwise invisible beam.

Infrared sensors play a crucial role in robotics, allowing robots to detect objects and navigate their environment.

A type of resistor made using semiconductor materials. These resistors are often used in high-frequency and high-precision applications.

A type of IR sensor that uses a single receiver to detect IR radiation emitted from an object.

The tolerance of a resistor is a range of values it can fall within. It is expressed as a percentage of the nominal resistance value.

The power rating of a resistor is the maximum amount of power it can dissipate without overheating and damaging itself.

A type of IR sensor that uses both a transmitter and a receiver, sending out IR radiation and detecting its reflection from an object.

The output of an IR LED is often too weak to directly power a standard LED. This issue can be resolved by using a resistor in series to control the current flow.

E6, E12, and E24 are standard series referring to the preferred values of resistors. E6 has 6 values per decade, E12 has 12, and E24 has 24.

Resistors are used in electronic circuits to limit the flow of current and are measured in Ohms.

IR LEDs produce a lot of heat, which can damage the device and reduce its lifespan.

IR radiation can be detected by a mobile camera, even if it's invisible to the human eye.

CR is used as a prefix for carbon composite resistors. WH or W is used as a prefix for wire wound resistors.

Specialized motors that use gears to reduce speed and increase torque, ideal for applications requiring high force but slower movement.

An electronic component that acts as a bridge, controlling the direction of current flow and powering the motor.

A motor with a unique rotational mechanism that moves in precise steps, controlled by a specific circuit known as a driver.

A stepper motor where the windings are connected to a single common terminal.

A stepper motor with separate windings, requiring two connections each.
