Motors, Servos and Actuators
Motors, servos, and actuators provide motion for robots, machines, and actuating mechanisms. Depending on the system design, DC motors, BLDC motors, stepper motors, servos, and linear actuators can be selected according to supply voltage, speed, torque, travel range, and control method.
Wheels, Tracks and Robot Chassis
Drive system components enable the construction of mobile platforms and robots designed to move across different surfaces. Wheels, tracks, ball casters, and robot chassis can be used to assemble mobile platforms and match the mechanical structure to the propulsion system, required load capacity, and intended movement characteristics.
Mounting Components and Brackets
Mounting components provide mechanical connections between parts and support the construction of complete devices. Brackets, mounts, and other structural accessories can be used to install motors, sensors, electronic boards, and additional components in robotics, automation, and prototyping projects.
Grippers, Electromagnets and Actuating Components
Grippers and electromagnets can be used to build mechanisms for gripping, holding, and moving objects. Combined with suitable drives and control systems, they can be integrated into robotic manipulators, automation mechanisms, and prototype systems.
Pumps and Solenoid Valves
Pumps and solenoid valves are used in systems requiring the transfer or control of liquids and gases. Parameters such as supply voltage, flow rate, pressure, connection diameter, and compatible medium help determine suitability for pneumatic, hydraulic, dosing, and cooling systems.
Enclosures and Structural Accessories
Enclosures protect electronics and other device components against mechanical damage and environmental conditions within the protection capabilities of a particular design. Enclosure accessories and mounting components facilitate the installation of circuit boards, cables, connectors, and other components inside a device.
Selecting Mechanical Components
Mechanical components should be selected according to dimensions, mounting method, material, load requirements, and mechanical and electrical compatibility. For drive systems, additional parameters such as torque, speed, supply voltage, and the method of transferring mechanical power should also be considered.
