2. 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 necessary or at least helpful?
What specific characteristics would designers need to include in such a robot?

3. a robot is a mechanical device that is capable of performing a variety of tasks on command or according to instructions programmed in advance.

4. 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

5. Automation vs. robots Automation
–Machinery designed to carry out a specific task
Bottling machine
Dishwasher

6. Automation vs. robots Robots
– machinery programmed to carry out different tasks
Pick and place arms
Mobile robots
Computer Numerical Control machines

7. Ideal Tasks Dangerous environments Space exploration
chemical spill cleanup
disarming bombs
disaster cleanup

8. Boring and/or repetitive tasks
Welding car frames
Picking and placing parts
manufacturing parts
Paint spraying.

9. High precision or high speed tasks
precision machining
Electronics testing
Surgery

10. Continuous path control robots
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.

11. 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
robotrace video

12. 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

13. New directions Haptics--tactile sensing Other kinematic mechanisms,
e.g. snake motion
Artificial neural networks
Robots that can learn
