Design Specs: Goals of the Arm

This is the list of goals and design specifications that will be met in the 3D printed arm part of this project. There will be two phases on the mechanical design. A very simple low cost arm and a more capable but expensive arm

Low Cost Arm

1. Aside from screws all structural components must be 3-D printed (using makerbot)
2. Excluding the microcontroller, component cost must be <$25
3. Arm must lift 1.5 oz at maximum extension
4. May only use a single type of servo
5. Controlled from keyboard (no more than 6 keys)
6. <5 3D printed parts

Higher Cost Arm

1. Modular gripper that can hold writing utensil
2. Excluding the microcontroller, component cost must be <$40
3. May only use a single type of servo
4. Controlled by mouse
5. <8 3D printed parts

Future Expansions

1. Trainer Pendant Arm
2. Sense and Follow
3. Implement with webcam to collect objects and draw picture
4. More grippers
