Robotic Arm Classification: Power Source

Robotic arms can be classified based on power sources. Each of these differ in size, capabilities, and parts. Explore more below!

Electrical Power

These main sources of electrical power for robotic arms are batteries. The type of battery that is used depends on the safety and life cycle. DS batteries have a higher torque, but more maintenance and parts. AC batteries are used in larger capacity, industrial robots that would require more power. 

Pneumatic Power

Robotic arms use pneumatic power to perform movements. Pneumatics is a branch of engineering that deals with the use of compressed air or gas to generate mechanical motion. Pneumatic power is used for high speed robots but they are less precise and noisy. 

Hydraulic Power

Hydraulic power is commonly used in robotic arms to provide the necessary control for various applications. Hydraulic systems utilize fluid, typically oil, to transmit power to create mechanical motion. Often this type of power is used for very large capacity robots, this requires a lot of power and can be noisy.
