- Reduce size of all parts within base to make it smaller and more portable
Make arm larger to increase drawing area
Make clutch system virtually wireless to avoid tangling of wires when the base rotates
Distribute weight evenly to avoid uneven stresses on motor shaft and sagging of base
If the Design drawing table is necessary, cut the hole properly such that entire mount system and arm gear fits through to allow smooth operationsuch that the arm bevel gear arrangement fits through properly and such that the gears are always in mesh and the arm can be properly controlled by the arm shaft.
- Better way to fasten things together, i.e. heat set screw inserts
- Modular design from the start, i.e. no hot glue, epoxy, elmer’s glue, etc.
- Retractable components for things like table legs, link lengths, etc.
- Caster wheel supports at the bottom of assembly to offload weight from motor shaft and make the overall assembly more stable
- Undergo multiple prototype and testing phases to refine the product further.
- Consider a more tactile controller such as a rollerball where the ball can be rolled by the user and the system responds accordingly. This would also be easier and more engaging for the children.
