These are robot that are fixed in
position. They tend to have robot arms that can move about. The diagram below shows a
large-scale stationary robot arm. It has
mobile joints called ‘the wrist’, ‘the
elbow’, ‘the waist’ and ‘the shoulder’.

1. Welding Robots: What the advantages of using robots for this work?
2. Painting Robots: Imagine doing this 24/7 exactly the same each time!
3. Strong Robots: how many people would it take to do this work?
4. Synchronised Robots: Imagine all these working together in a line? Just think how quickly you could make things!

Robot Anatomy
Stationary Robots can be described in terms of joints and the directions they move. This is very similar to human anatomy and the direction the arm can move.
Waist: Moves from Side to Side at the Waist
Shoulder: Moves Up and Down from the Shoulder
Elbow: Move Up and Down at the Elbow
Wrist: Move from Side to Side and Rotates around the wrist.

Robot End Effectors (tools fitted on the end of a robot arm)
A whole range of tools can be fitted to
the end of a robot arm, for example a
spray gun, a welding gun, a gripper, etc. Examples of various end effectors can be seen on the right.
Thinking back to the Linn Systems factory,
the robot arms were relatively small,
were fitted to
the production line and had a tool fitted to enable them to place parts on the
circuit boards.
This tool could be changed to enable the arm to place a range
of different electronic parts on the circuit board.
What you have to do!
Either in a new Word Document or in your Brain. Under a sub heading Stationary Robots and Tools complete the following tasks after watching each of the videos above:
Think about what happened to the people who used to do the jobs shown in the videos. What do you think they are doing now?
Explain what is meant by 'Degrees of Freedom"
Provide examples of work which would be completed by each of example end effectors. i.e what would they be used for?
If you changed the tool at the end of the robotic arm, explain what else you would have to change?
What you should now be able to do!
Explain what is meant by Stationary Robots.
Provide several examples of different types of work completed by stationary robots and give some reasons why they are used for this work.
Give some examples of tools that could be bolted on to the end of robot arm.
