Functional Demo Materials
Full Device
Mechanical Systems
- The motor and belt system moves the gripper in x and y directions
- Stepper motors to track locations
- PVC for smooth drawing surface
- 80/20 and T-nuts for structure during transportation
- Plastic electronics enclosure
- Magnetic sheet for paper attachment
Gripper
- 3D Printed Design
- Servos open/close and raise/lower jaws
- Accommodates different tool sizes
Electronics
- The device plugs into the wall and converts to DC
- Buck converters convert 12V to component voltages
- Raspberry Pi controls servos and motors via motorPlate and code
Teacher Input
- Programmed in Python, displayed on the touch screen
- Allows device set-up through inputting the paper size and changing the sensitivity of movement and pressure based on the tool
- Can override student input if needed
Student Interface
- Wheelchair table attaches to the wheelchair
- Velcro mats to hold components in place
- Velcro attachments allow different input configurations to best accommodate each student
- Two input methods
- 4 directional buttons, draw/not draw button
- Joystick for directional movement, draw/not draw button
Plans for "Next Phase"
- As a team, what would you do if you had another 3 weeks to work on this project?
- Automatic tool pickup and drop off
- More portable device - add handles/carrying case
- Smoother belt/gripper motion
- Easier access to electronics & increased client repairability
- Individual Plans for "Next Phase"
