Robots are driven using actuators which control the robotic arm from an input signal. They can use hydraulic (large robots), pneumatic(small actuators with simple control movements) or electrical principles of operation.
A computer sends instructions in electrical signals or pulses. An interface converts these digital pulses into analogue electricity for the motors. The robot is fitted with sensors which can send feedback on the position of the robot.

Robotic welding Terms

Lead through programming  Teaching robot movements through guiding it manually through a sequence of operations. These are recorded to memeory
Machine Vision Area of vision robot has, limits which robot sensors can operate
Working enevelope The area within which a robot can operate. Where the work is caried out by robotic arm
Yaw left and right movment of robotic arm
Roll  rotation of robot about one of its axis
Degrees of freedom These are the number of independent movements of the arm joints( or actuators) the robot has. 

Advantages of Robotic welding

•Faster production rates
•Efficent continous operation
•Safe working practice
•Reliable and consistent welds
•Full automation
•Cost effective
