Robot Parts

A robot is a complex assembly of several parts and devices which are synchronized to perform specific functions. Whether you are a robot hobbyist or a robotic technician, you require robot parts to customize or repair the structure. However, proper care is required while buying robot parts to ensure that they align with the system.

Essential Robot Parts

Some of the most crucial robot parts are:

Robot sensors: Robots' intelligence depends highly on their sensors. The sensors detect elements in the surrounding environment and send information to the controller. Based on this information, the controller makes its decisions. Generally, a robot has several sensors to scan the environment. Sensors can include ultrasonic range finders to measure point distances, laser scanners to measure 2D and 3D distances for mapping, sound sensors, light sensors and more.

Microcontrollers: Microcontrollers act as the brain of robotic projects. These devices work similar to the central processing unit of the computer. They are capable of collecting information, processing it and deciding the actions of the robot.

Motor: A motor converts electricity into mechanical motion. There are different types of motors, which differ in terms of size, functionality and the amount of power they generate. Motor controller: This device acts as an intermediate between a microcontroller and a motor. A microcontroller is not capable of proving enough power to a motor so instead it sends commands to a motor controller which handles the higher power requirements.

Mechanical parts: Mechanical parts come in different forms and shapes. Mechanical parts are chosen based on the specific objectives of a robot. Certain common mechanical parts are wheels, tracks, casters, connectors, motor mounts, pan and tilt systems, gear boxes, chassis/frame and grippers.

Power system: Most robots require a battery to function. Many employ a Nickel Metal Hydride (NiMH), Nickel-Cadmium (NiCd) or Lithium-ion (Li-ion) battery, though others may use alkaline, lead acid or other less common types. Some robots are powered or recharged by solar energy. Standard power equipments often include battery, charger and adapters.

Communication devices: Optimum performance of a robot depends on successful communication. Robotic structures come with sophisticated communication and control devices for transmitting and processing messages. Essential communication devices include modem, Bluetooth, remote control and telemetry.

Purchase robot parts from authorized sellers who possess considerable industry experience. RobotShop is an internationally renowned source for buying robotic parts.
