1. + Building a Robot Arm Moshe Kam Yvonne Pelham D.G. Gorham TISP: Shenzhen 7-8 July 2009

2. + Moshe Kam IEEE Educational Activities Build your own Robotic Arm 2

3. + Robot Arm We will build a robot arm from simple materials The arm must pick up a paper cup from a distance of 45cm Lift the cup to a height of at least 15cm Bring the cup back to rest and release it 3

4. + Robot Arm You cannot get too close… You cannot get any closer than 45cm to the cup at any time Cup Student Robot Arm 45cm 4

5. + Robot Arm Steel Wire Cardboard Clothespins Ice cream sticks Rubber bands Binder clips Paper clips Small pencils Tape Paper fasteners Plastic bag Fishing lines Strings Available Materials 5

6. + Robot Arm Divide into teams of two (2) Review the requirements Discuss a solution and create a sketch of your design Build a model of your design with given materials Test your model Outline and Procedures 6

7. + Robot Arm Discuss and agree upon a redesign If needed after testing, or to enhance the previous design Rebuild your robot arm Retest your model Answer reflection questions as a team Redesign after testing 7

8. + Robot Arm What was one thing you liked about your design? What is its main weakness? What is one thing you would change about your design based on your experience Are there algebraic and physical principles that can be applied to this activity? How would you modify the instructions to create a better experience for the participants? Reflection Questions 8

9. + Robot Arm The arm must pick up a plastic cup from a distance of 45cm Lift the cup to a height of at least 15cm Bring the cup back to rest and release it Design requirements 9

10. + NEW DESIGN REQUIREMENT Lift and release the cup when it is upside down Robot Arm UPDATE FROM SPACE AGENCY 10

11. + Robot Arm 1. The arm must pick up a plastic cup from a distance of 45cm Lift the cup to a height of at least 15cm Bring the cup back to rest and release it 2. Lift and release the cup when it is upside down Design requirements 11

12. + NEW DESIGN REQUIREMENT Lift and release the cup when it is full of water Robot Arm UPDATE FROM SPACE AGENCY 12

13. + Robot Arm 1. The arm must pick up a plastic cup from a distance of 45cm Lift the cup to a height of at least 15cm Bring the cup back to rest and release it 2. Lift and release the cup when it is upside down 3. Lift and release the cup when it is full of water Design requirements 13

14. + NEW DESIGN REQUIREMENT Need a single device that can manipulate a cup as well as a pen. Device can use two different end manipulators Robot Arm UPDATE FROM SPACE AGENCY 14

15. + Robot Arm 1. The arm must pick up a plastic cup from a distance of 45cm Lift the cup to a height of at least 15cm Bring the cup back to rest and release it 2. Lift and release the cup when it is upside down 3. Lift and release the cup when it is full of water 4. Use the same design (possibly with a modified end manipulator) to lift a pen Design requirements 15
