3.Where do the ideas for how robots work come from?
4.Can you think of a situation in which a robot would be necessary or at least helpful?
5.What specific characteristics would designers need to include in such a robot?
What is a robot?
Does it have to look like a human?
Why do engineers design and build robots?
Where do the ideas for how robots work come from?
Can you think of a situation in which a robot would be

What specific characteristics would designers need to
include in such a robot?
a robot is a mechanical device that
is capable of performing a variety
of tasks on command or according
to instructions programmed in
advance.
Robotics and AI
Robotics is the study of the design, construction
and use of robots
Artificial Intelligence is the branch of computer
science that deals with writing computer programs
that can solve problems creatively
Automation vs. robots
• Automation
–Machinery designed to carry out a specific task
– Bottling machine
– Dishwasher
Automation vs. robots
• Robots
– machinery programmed to carry out different tasks
– Pick and place arms
– Mobile robots
– Computer Numerical Control machines
Ideal Tasks
Dangerous environments
• Space exploration
• chemical spill cleanup
• disarming bombs
• disaster cleanup
Boring and/or repetitive tasks
• Welding car frames
• Picking and placing parts
• manufacturing parts
• Paint spraying.
High precision or high speed tasks
• precision machining
• Electronics testing
• Surgery
Pick and Place robots
• Moves items from one point to another
• Does not need to follow a specific path
between points
• Uses include loading and unloading
machines, placing components on circuit
boards, and moving parts off conveyor
belts.
Continuous path control robots
• Moves along a specific path
• Uses include welding, cutting,
machining parts.
Sensory robots
• Use sensors for feedback.
• Eg optical sensors, cameras,
pressure sensors, temperature
sensors, sonar.
• Closed-loop robots use sensors
and actuators to gain higher
accuracy

Controlling robots
•Open loop, i.e., no feedback, deterministic
•Closed loop, i.e., receives feedback from
sensors, maybe a sense of touch and/or
vision
New directions
• Haptics--tactile sensing
• Other kinematic mechanisms,
e.g. snake motion
•Artificial neural networks
• Robots that can learn
