  1. Prosthetic Arm • 2019-2020

  2. Learning Objectives • By the end of the session, participants will be able to: • Explain the rules to students, • Identify the major bones and joints of the arm, and • Create a prosthetic arm from available materials to pick up an object.

  4. Prosthetic Arm Rules Middle School (6 and 7/8) High School (9/10 and 11/12) • Design, construct, and operate a simulated prosthetic arm • Grab and release bean bags into Target Zone as fast as possible • One at a time • Device must have at least two artificial fingers. • At least two fingers must open and close • Must grab and release object • Design, construct, and operate a simulated prosthetic arm • Grab, stack, and release plastic cups into a pyramid in fastest time • One at a time • Device must have at least two artificial fingers. • At least two fingers must open and close • Must grab and release object

  5. Prosthetic Arm Rules Middle School (6 and 7/8) High School (9/10 and 11/12) • May use any material, except hazardous ones • NOT controlled or operated by either member’s fingers, hands, or wrists • Own method of immobilization • May use unencumbered hand to hold or move bucket • May use any material, except hazardous ones • NOT controlled or operated by either member’s fingers, hands, or wrists • Own method of immobilization • May use unencumbered hand to hold or move bucket

  6. Middle School Competition Area Specs • Plastic All-Purpose bucket • Skeet Ball Target Zone • Bean bags • Count # of bean bags on initial impact inside of scoring zones

  7. High School Competition Area Specs Working Area Table / Task Area Task Area (60 cm) • Standard six foot table • 21 pre-stacked red 16 ounce plastic cold cups • Bounce Free and Soft dryer sheets • Count # of cups successfully stacked on second tier or higher at end of trial 74 cm 180 cm

  8. Engineering Lab Book • Include sketches of human arm and device iterations with correctly labeled structures. • Include Materials Table.

  9. Activity: Bones and Joints Objective: Identify the major bones and joints of the human arm

  10. Bones and Joints of the Upper Extremity • Humerus • The longest and largest bone in the upper extremity • Radius • The other bone of the forearm, shorter than the ulna. • Ulna • A long bone in the forearm parallel with the radius; at the proximal is the elbow and the distal end is the wrist. • Shoulder Joint/Complex • Elbow Joint/Complex • Humeroulnar Joint – simple hinge-joint • Humeroradial Joint – arthorodial joint allowing gliding and sliding motions • Proximal Radioulnar Joint – pivot joint

  11. Bones of the Hand • Carpals • The wrist is composed of 8 separate carpal bones. • Metacarpals • The intermediate part of the hand skeleton that is between the carpals and the phalanges (up to the knuckles); 5 metacarpal cylindrical bones • Phalanges • The fingers of the hand contain 14 digital bones.

  12. Joints of the Hand • Metacarpophalangeal Joints • Interphalangeal Joints • Wrist Joint • Radiocarpal joint • Carpometacarpal joint • Intercarpal joints intercarpal joints carpometacarpal joint midcarpal joint radiocarpal joint interphalangeal joints

  13. Activity: Grab and Release an Object • Supplies per Group: • 2 sheets of card stock paper • 9 straws • 14 craft sticks • 3 pony beads • General Supplies: • Various objects such as empty paper clip box and empty water bottle • Glue gun • Scissors • Masking tape • A few bamboo skewers • Rolls of string Objective: Design, build, and operate a prosthetic arm from given supplies to grab various objects one at a time and release them

  14. Activity: Grab and Release an Object • Using the given supplies, design and build a prosthetic arm to grab and release an object. • Device MUST have at least two artificial fingers. • At least two artificial fingers MUST open and close. • Can NOT use opposite fingers, hand, or wrist OR the real hand to operate or control the prosthetic arm. This is a simulation. • See Activity Sheet for instructions to create one finger with two joints. Your group may create the finger with additional joints. • After creating one finger, your group will create another one or more fingers. • Use the remaining supplies to create the arm and the operation of the fingers. • Attach the prosthetic arm and pick up the different objects from a table one at a time and release.

  15. Activity: The Pick-Up Challenge • Supplies per Group: • 2 cups • 3 ft of string • 10 rubber bands • 1 pair plastic glove • 10 craft sticks • 2 sheets of paper • 10 straws • General Supplies: • Scissors • Masking tape • Various objects to pick up Objective: To design and build a prosthetic arm device to safely pick up things.

  16. Activity: The Pick-Up Challenge • Prosthetic arm must be a working model with moveable parts. Tape cannot be used by itself or as a “lasso” to pick up objects. • Must be able to pick up objects without outside assistance. • Device must be self-contained (e.g., device cannot be anchored or tethered). • Device must be controlled using only one armor opposite hand.
