This is a 3D printed version of Joop Brokking's laser cut (Oops. CNC Router cut) self balancing robot
He has some really great detailed projects. Have a look!
Please note!!! I have not tested this as yet. The box with my stepper motors has gone missing somewhere in my shed. If you saw my shed, you may understand ;)
The Tinkercad files are here...
The frame is screwed together with M3x15 screws just into the plastic. Nuts may be added if you think it is needed.
So far, I have not made the mount for the circuit boards.
Some additions may be to also include ultrasonic sensors....
And a transmitter case could be the next step.
It is odd how you find things when looking for something else.
I found the motors. But they have pulleys on the shafts so I will mod the wheels to suit.
Motors mounted with 4 M3x10 screws.
The modified wheels went on, sort off. Each motor has a different size pulley! Super glue will help.
I have made no provision in this version for holes to mount the circuit board. That will be version 2, maybe.
EDIT: I have started the electronics assembly. The accelerometer works ok but I had a wiring error on the stepper drivers. I fixed that, then, for some reason, the Arduino is no longer programming :(
At this time, I can't be bothered unsoldering everything to get the the Arduino off the board so this project stops here for now.
Whatever floars your boat. But RED goes faster ;)
2 of each part is required to make the frame.
