2. Team Concept Automatic Jar and Bottle Opener Adjusts to containers within the following constraints:  Height: 2” – 10”  Body Diameter: 1.5” – 5”  Lid Diameter: 1” – 5”  Lid Height:.3” – 1”

3. Basic Operation  Upper Assembly moves up and down to accommodate various heights  Gripping mechanism within Upper Assembly adjusts to lid diameter and centers jar  Base grasps jar body and twists

4. Upper Assembly Lid Grasping Components  Two grooved plates  Dimensions of 3 lid grips  Sensors on lid grips

5. Upper Assembly Height Adjusting Components  Threaded gear & shaft  Gear assembly  Servo Motor

6. Lower Assembly Jar Grasping Components  2 motors, 2 worm gears  Spring and contact switch  Spring-loaded arms

7. Lower Assembly Jar Twisting Components  Servo motor and large gear  Rotating plate and flathead screws  Microprocessor and battery housing
