Single-point self balancing cube inspired by Cubli 🔶 Gadgetify

This is a programmable self-balancing cube inspired by Cubli (credit: Gajamohan Mohanarajah). It can keep its balance on a single point or one side. You will simply have to set the 0 (balance) point, which you can see through the OLED display. As long as the surface is not slippery, the cube should be able to stay balanced.

This cubli clone has a STM32F103RCT6 microcontroller, 2 batteries, 3 flywheels, and brushless motors. It runs on 550mah batteries. It has an Android app for further experiments.

do you have a video on how to build it ?

[@jhengineering3578]

Is there a way to farther tune the control algorithm/values that could improve on the balancing performance? This self-balancing cube is rather noisy and has more motion when it's balancing.

[@Gadgetify]

you can fine tune the algorithm. Yes. It is supposed to not make a whole lot of noise when perfectly balanced.

Awesome! Is this project open source? Would like to learn more about how it works!

[@gokarnabaskota4242]

Could you provide me the more info about it? I have this system but I am not aware of the system and pin diagrams.

[@Gadgetify]

what question do you have about it? I can try to answer. You just have to 0 the x, y, and z axis and then click one of the buttons on the side and gently release the cube.

@@Gadgetify Thanks, But how to manipulate that cube with own code. I can't find any resources about the board and other stuffs. Can you explain me that way?

[@nazmdar]

What sensor did you use to measure axis angles?

[@milesalderman]

Check out the MPU-6050. It is a well documented 6 axis imu

[@origamimasters5626]

so it uses gyroscopic stabilization to keep it upright?

[@Gadgetify]

yes, 3 motors that activate as soon as the board detects disturbance on an axis. It's definitely not as capable as the original Cubli or anything.

No, not gyroscopes, but, reaction wheels.

[@wardweirdword6677]

what is the type of the brushless dc motor you have used??

[@blak-insel2333]

We all want to know !
