1. Introduction to Robotics Part 1 Direct Control Robots and Robotic systems.

2. Systems “Humans must be able to create, control and monitor systems.”

3. Definition System:a group of parts/machines working together to perform a task Two types of systems- a.natural-human body,weather and ecosystems.Can only be monitored by humans b. Technological-human made to solve problems

4. Sub Systems Smaller system(s) operating as part of a larger system. Ex. System =Laptop computer Subsystem=Keyboard, flat monitor, controller and speakers

5. Open loop system Open Loop System: a system designed to do a task repeatedly without being able to adjust itself. Lamp Mouse trap Door handle Clock Process Output Input

6. Parts of a System Input: the goal you want to achieve Process Output Input Process: Action part of system Output: The actual result of a system

7. What is a “Robot” Robot- A machine that is able to interact with and respond to its environment. characterized by three central capabilities: the ability to Sense (input), the ability to Plan (process), and the ability to Act (output).

8. What is Direct Control? Direct Control- A machine or system that is unable able interact with and respond to its environment with out human involvement In other words humans are the part of the system. An example is an RC car. It can not move without us telling it to move.

9. Where is the applicable?

10. Medical Field

11. Law Enforcement/ Military

12. Exploration Mars Rover Sewerbot

13. Manufacturing AND MUCH MORE!

14. Human Robot We will need a volunteer to be our robot. The robot will have to keep there eyes closed and move slowly during this exercise. The robot is only allow to do what the operator tells it to do. We also need a volunteer to control or robot.

15. Controlling the Human Robot Place your hand on the right shoulder of the robot to move the robot right. Place hand on the left shoulder to move the robot left. Place hands on both the left and right should to move the robot forward. The robot is only allowed to move when the controller give it a command. Lets try it out!

16. Closed loop system Closed Loop System: designed to do a task and check for errors, then it will try to correct the errors. InputOutput Process Vehicle uses motors to move forward and follow black line -Drive motor B & C forward -Wait for darker -Drive motor A backward -Wait for lighter Car follows black line Feedback/Monitor Robot checks for black line

17. Feedback/Monitor Compares the output to the input. If the output does not match the input this device will modify the process so that our desired result occurs.

18. Modern Feedback Loops Made up of three parts Sensors-used to observe output of the system(monitor) Comparators- compares actual output to the command input (compare) Controllers- Modifies the process by turning it on and off or by adjusting it (adjust)

19. Sensor types:(monitor) Thermal optical electrical magnetic mechanical

20. Comparators:(Compare) Human brain- Decides Computer/computer chip- Artificial intelligence Transducer- senses and compares

21. Controllers- adjust the process Human operator electricalmechanical hydraulics pneumatics
