A Jointed Arm robot has
three rotational axes connecting three rigid
links and a base. An Jointed Arm robot is
frequently called an anthropomorphic arm
because it closely resembles a human arm.
The first joint above the base is referred
to as the shoulder. The shoulder joint is
connected to the upper arm, which is connected
at the elbow joint.
Jointed Arm robots are suitable
for a wide variety of industrial tasks,
ranging from welding to assembly.
