| | Assignment VI:
| 3) Possible answers:
1. He studied Mechanical engineering with one year of Electrical and electronic engineering.
2. Because production was going through the roof, their old system simply could not produce enough phones.
3. It uses biosensors, which are coated in enzymes to measure the blood glucose levels in a drop of blood. Basically how much sugar there is in the blood.
4. Because there can’t be any contamination, monitors have to be perfectly clean, and there can’t be any defects in the production.
5. They don’t simply pick up and components blindly. They can see what they are doing, they can teach themselves, and they check everywhere move they make to ensure there are no errors.
6. An engineer must be innovative, able to work across functions and communicate with non-technical people.

Unit 3
| Assignment I:
| 2) Possible notes:
Dimension sensors determine the size of the room. The robot cleaner sends an infrared signal in each direction and reflecting from the walls returns to an infrared receiver.
When the cleaner hits an object the bumper is pressed in. This activates mechanical object sensors. These send signals to the processor which cause the cleaner to change direction to avoid the object.
Cliff sensors are placed under the cleaner and directed downwards. If the time taken for the return infrared signal increases suddenly, the processor detects a ‘cliff’, for example, stairs or other sudden drops which the robot to reverse away from the cliff.
The wall sensors let the cleaner follow walls and go round objects closely but without touching them.
Dirt sensors are acoustic impact sensors. When the cleaner raises a lot of dirt from any surface, some of the dirt hits the metal place of the acoustic impact sensors. This causes vibration which the sensors detect. They pass a signal to the processor which causes the robot to clean the area.

| Possible answers
A) 1. The applications of robots can be divided into three categories: material handling; processing operations; assembly and inspection.
2. Robot needs to be equipped with material transfer to do loading and unloading operations.
3. The robot manipulates a tool to perform a process on the work part.
4. Spot welding of automobile bodies is one of the most common applications of industrial robots.
5. The main reasons to use robots in production are the high cost of manual labor and providing a substitute for human labor.
6. In a typical inspection job, the robot positions a sensor with respect to the work part and determines if the part answers the quality specifications.
7. Material handling is the transfer of material and loading and unloading of machines
8. Examples of robotic processing operations include spot welding, continuous arc welding and spray painting.
9. Because the operations with nuts and screws are extremely difficult for a one-armed robot.
10. Yes, they are.Most robots are used in manufacturing operations nowadays.
B) 1. Heat sensors are important for robots working in extreme conditions.
2. The problem with batteries is that they are heavy and run down quite quickly.
3. Soon after the first machine-tools appeared late in the 18th century, engineers modified them so that they could work by themselves for some of the time.
4. Second generation computers with transistors application were smaller than the first one / first generation computers and consumed less electric power.
