A Walk Down Memory Lane....

It's about time that I started posting about robotics and electronics, in addition to the woodworking...

First up is my Senior Project - an "Inverted Pendulum" robot. That is, a robot that balances on two wheels. I will post and comment on the pictures that I took during the building of the chassis, and initial electronics work. I will then post schematics, and code.


I will call the is the first version of the robot or "V1".  The V1 robot is marginal in its ability to balance, due to a combination of poor sensor placement, less than Ideal programming of the robot, and motors that are too slow. Additionally, I had to remove the microprocessor in order to update its programming. The resulting overuse of the ZIF socket resulted in a growing electronic unreliability.
I intend to address these problems in the V2 robot.


Without further ado, the building of my robot:


Chassis parts.

Nice thing about this design, it that all the pieces are 1" x 6", which was very quick to mill and assemble.

Adhesives used.

Start of assembly.

The pencil lines are to assist alignment later....

Almost there!
Glued together, ready for further work.

In the future, I would drill all the needed holes before assembling. Overall would be much faster then drilling  holes in the assembled chassis, as I did in this build.
