Question $(1)$: $[12$ Marks$]$

An example of mechatronic systems is a robotic arm used to assemble heavy$-$duty parts in an

industrial production line. It needs to move the parts from location to another both quickly and

precisely. In the light of your knowledge about the design and development of mechatronic products:

a$)$ Suggest the appropriate type of actuator that can be used to drive the robot. Justify your

Answer.
