Project Development

Back

What tasks have been completed, and what tasks remain?

Complete is the electronic design and production.
3D design and printing to create a suport structure and a wheel.
Embedded programing to creathe the code who convert the g-code in number of steps and direction.
Molding and casing to create the mold of the wheel
Composites to create a material flexible and subjection to the floor to cover the wheel.
Computer controlled machining to create a wheelChair prototype.

Remain stability with more wheels and add a power bank.

What has worked? what hasn't?

This system works with atmega328 to process the information adquired of a SD Card, A4988 stepper driver to controll the stepper motor NEMA 17 with the signals recived of the micro controller, SD Card Module to read the g-code of the SD Card and a external source voltage to powe the system.

this system is not working with power bank ( battery ) because it is a small prototype, I am going to follow working in this project to change the way to work wit a battery to power the system and to obtain a better control system.

What questions need to be resolved?

What kind of applications could be resolved with this system?
How strong is the wheel?
What will look interesting?
How wheel with CNC propierties are made?
How can transform the data to proses on my wheel?
How can i do to work with different formats of g-code?

What will happen when?

What will happen when the system has to process a g-code really big or if the system turn off when it is processing a code.
The g-code is in a diferent format, the system work in diferents formats or just with a specific format.
The machine turn off without power.

What have you learned?

3D design and printing to generate the supports, wheel and molds.
Electronic production and design to create a board to controll the system.
Embedded program to read the g-code of the SD Card and covert to movement.
Composites to generate the wheel.
Also I learned about Creative commons an Invention, Intellectual Property and Business Models to apply to my projects.
