5. Listen again. Each participant mentions some strengths and
weaknesses of the robots, and suggest some improvements. Complete
the form.
ROBOT USED SURVEY FORM
USER #1 OCCUPATION: Construction engineer ROBOT NAME: Snakebot
Function of robot It is used to take forgotten tools on top of buildings.
Strength(s) Can twist around girders, pipes and scaffolding. Can bring tools
Weakness(es) Can only be controlled with a joystick
Improvement(s) Install proximity sensors and a camera for object detection, thus
giving you an indication of which tool we need.
USER #2 OCCUPATION: Emergency response ROBOT NAME: Rescue Robot
Function of robot Used in hospitals to perform surgeries
Strength(s) It can operate in very small spaces, it has 360 degree movement,
it is more precise than a human hand.
Weakness(es) can only see in one direction
Improvement(s) Install a camera with a wide angle and a larger focal aperture to
have a greater range of visibility.
7. Tell the class about the strengths and weaknesses of some of these
products and/or any others you have problems with. Suggest
improvements.
Computer keyboard, earphones, sunglasses, mobile phone.
Dzul May Humberto Antonio IMI101
What are some strengths and weaknesses of an earphones?
The biggest strength of earphones is that it is portable and allows us to take it
anywhere, because they are small. One weakness could be that they are not
compatible with all cell phones.
What would you suggest to improve it?
An improvement would be to make them waterproof and they should increase the
battery life in the case of the Bluetooth type.
What are some strengths and weaknesses of a sunglasses?
The biggest strength of sunglasses is that they are portable and us help prevent damage
from the sun's ultraviolet rays. One weakness could be that they are brittle and easy to
break.
What would you suggest to improve it?
One improvement would be to make the frames them elastic and more resistant to falls. /
They should make that polymers are more resistant to scratch and breaks.
What are some strengths and weaknesses of a smartphone?
The biggest strength is that a smartphone is portable allows us to communicate with other
devices, without the need for a wired connection. One weakness could be that they are
easy to lose and also have fragile screens.
What would you suggest to improve it?
An improvement would be to strengthen the screens so that they are resistant to falls. They
should include reinforced screens on all mid- and upper-range cell phones.
What are some strengths and weaknesses of a computer keyboard?
The biggest strength of the keyboard is that we can type easily and can be cleaned
easily. One weakness could be that they are not comfortable due to the letter travel
with the keys.
What would you suggest to improve it?
An improvement would be to make them more resistant and less noisy at the time of
writing.
8. Work in pairs, A and B.
ROBOT USER SURVEY
Occupation of user Safety inspector of buildings
Name of robot Robo inspector
Function of robot Inspect buildings
Frequency of use 60% of the buildings.
Specifications of robot Weighs about 1kg and has three wheels
How it works Creates strong vacuum – can adhere to hard surfaces.
Strength(s) It can move quickly across ceilings and climb brick walls.
Weakness(es) If use two or three at the same time, they crash into each
other.
Suggest improvement(s) Implement presence sensors and synchronize it with the
robot's brakes to stop when detecting a nearby object.

ROBOT USER SURVEY
Occupation of user Hospital surgeon
Name of robot Robo surgeon
Function of robot Used in hospital operations
Frequency of use Once or twice a month
Specifications of robot Four arms
How it works It’s controlled from a console by surgeon
Strength(s) It can operate in very small spaces, it has 360 degree
movement, it is more precise than a human hand.
Weakness(es) can only see in one direction
Suggest improvement(s) Install a camera with a wide angle and a larger focal
aperture to have a greater range of visibility.
9. Write a short report about your partner’s robot and how it could be
improved. Use the information from the form.
The robot surgeon can be fitted with a camera with a larger focal aperture
in order to have a greater range of visibility when performing surgeries. A
camera can be installed on each arm for different viewing angles.

The engine produces thrust pushes in the plane forwards.
The gravity causes that the weight pulls the plane downwards.
The friction causes the plane to drag or pull backwards.
The shape of wing produces that the plane lift upwards.

3. The designers of the new planes in 2 worked from the designed brief below.
Discuss with your partner and choose:
The best design (the one closest to the design brief)
The worst design (the one furthest from the design brief)
The best design is the design A, because the engine needs 20% less fuel than
today’s plane engines, and the fuel consumption is one quarter less and the
shape of the plane allow air to flow more smoothly.
The worst design is the design C because the fuselage is flat, not cylindrical
and may not resist air pressure at high altitudes.

4. Design and improved product. Draw a diagram and write a description.
Include this information.
GROUPS D’S DESIGN BRIEF
Function AIRLESS TYRE
Shape and appearance Circular with holes every 5cm
Main parts Made up of a single piece
Dimensions 14”, 15”, 16” diameter.
Materials and properties plastic outer shell with internal polyurethane foam padding
Operation (how it works) it is replaced by a conventional tire and the vehicle studs are
tightened.
Cost $1200 per unit.
Method of manufacture the polymers are melted and the main casing is formed in
molds with the corresponding measurements, they are left to
dry until they reach the plastic form and after that they are
injected with polyurethane foam.
Safety features You can brake even in rainy conditions due to the non-slip
shape of the rim.
It weighs less than a conventional tire so it can be
exchanged in a practical and safe way.
As it does not have air, it has no pressure increase, it does not
need to be calibrated.
