Project Development

 

Fab Lab Addis / Fab Academy 2013

 

Movable and foldable stand

Finally I decided to complete my proposal option A for my final project.

Robotic architecture has been my interest for very long time and this proposal will increase my knowledge towards mechanical mechanisms and electrical systems. MY final project generally comprises of work on intense 3D printing and laser cutting. The 3d printing was used for components like wheels and connecting elements. Bars and planes was cut by laser cutters.

My project is to make a foldable and movable stand

The following pictures and descriptions show my project in a more elaborated way.

My Project is Briefly Shown in the following video link

Technical drawings of the movable stand as they were prepared for laser cutting

wheels, bolts and nuts (Components printed by our 3D printer)

The movable four bar stand under constructtion

The first board design has three components the stepper motor design and the button design, the little extension on the stepper motor board is like that because the original board and the final component i used for the regulator did not match.

Since the board was complicated and difficult to carry on with all the inconveniences I decided to combine all the components and create a new board as shown below.

This board as modified to combine the buttons and the stepper motor board

The LED array future project to the movable stand

The project is also to have an LED array clock project on the plane/ to be done the future. Here are some of the pictures and description to the project of the LED array clock
