Presentation Transcript

  1. Introduction to Robotics A Force of the Future

  2. What do we know?

  3. Robots of the media

  4. What will we learn?

  5. What will we learn? • What kinds of robots are there? • What are the parts of a robot? • How do robots move? • How do robots help us?

  6. What kinds of robots are there?

  7. Types of robots Simple Level Robots: • are automatic machines that extend human potential. • do work that humans can but should not do.

  8. Types of robots Middle Level Robots: • are programmable, multipurpose, electromechanical machines. • do work that humans normally do.

  9. Types of robots Complex Level Robots: • are reprogrammable, multifunctional, manipulators. • are designed to move materials, tools and parts through programmed paths. • are suited for a variety of tasks.

  10. What are the parts of a robot? • Manipulator • Pedestal • Controller • End Effectors • Power Source

  11. Manipulator (Mimics the human arm) • Base • Appendages • Shoulder • Arm • Grippers

  12. Pedestal (Human waist) • Supports the manipulator. • Acts as a counterbalance.

  13. Controller (The brain) • Issues instructions to the robot. • Controls peripheral devices. • Interfaces with robot. • Interfaces with humans.

  14. End Effectors (The hand) • Spray paint attachments • Welding attachments • Vacuum heads • Hands • Grippers

  15. Power Source (The food) • Electric • Pneumatic • Hydraulic

  16. How do robots move?

  37. Stop !! Time out !!

  38. Degrees of Freedom VS

  39. Degrees of Freedom • Rotating the base.

  40. Degrees of Freedom • Pivot the base of the arm.

  41. Degrees of Freedom • Bending the elbow.

  42. Degrees of Freedom • Wrist up and down.

  43. Degrees of Freedom • Wrist left and right.

  44. Degrees of Freedom • Rotating the wrist.

  45. Why is it important?

  46. Applications • Transporting materials, tools, equipment. • Assembling parts. • Quality control. • Cutting materials. • Others

  47. What did we learn?

  48. What did we learn? • How can robots be classified? • What are the major parts of a robot? • How can robots move? • How can robots help extend our potential?
