Parts Of a Robot
February 23rd, 2008 by bjkrobotics
A. The 5 main parts of a robot include: The arm, the controller, the drive, the end efector and the sensor
The Arm- The arm is the part of the robot that positions the end-effector and sencors to do the job they were programed too. Most robot arms resemble human arms this gives the robot a lot of ways to position itself in its environment.
The Controler- The computer that is used to program the robot is called the controler, it alows the robots to conect to a network and work with other robots/machines.
The Drive- The engine that drives the links of the robot usualy powered by air, water pressure or elctricity.
The End Effector- The ‘hand’ conected to the end of the robot, there are many variations of end effectors, depending on what the robot is designed to do e.g hold tools, grip onto things ect.
The Sensor- The sensor alows the robot it ‘examine’ its environment, it sends info about its surroundings back to its contoling computer and determines its next movement.

B. The 6 degrees of freedom: many robots today are made to resemble human arms, usualy they have a shoulder, elbow, wrist and fingers. They are made like this to alow the robot many different movements. Robots need the 6 degrees of freedom to preform simple tasks, since each direction a joint can move provides 1 degree. the robots have 3 joints ‘the shoulder, elbow and wrist’, 3×2=6.
