I tried to make my self balancing cube better
Рет қаралды 2,734
Ай бұрынI tried to make my cube balance better. I also redesigned it to make it easier to assemble.
ESP32 controller,
MPU6050 sensor,
three Nidec 24H brushless motors,
450-500 mAh 3S1P LiPo battery.
Cube frame is 3D printed.

Awesome! And thank you for sharing the code. I bought the motors after the first video, but still did not find time to build. This video motivates me to come back to the project.

Cool! very nice improvements. Nice redesign corner fasteners and no need to use tape anymore. I like the reposition of the mpu6050. The new code and firmware is so much smoother and solid. Keep up the good work and Mahalo for sharing Rem!

What is your overall preferences for the motors, either those used in this project, or FOC +BLDC in your balancing triangle?
@ReMRC 25 күн бұрын
Nidec24H is an easy way because there is a controller inside. FOC + BLDC can also be used.

What did you change to improve the balancing? Is it just the encoders that makes all the difference? Or did you change the balancing algorithm. It looks so much better!
@ReMRC 25 күн бұрын
Encoders have poor resolution. But it helps a little. However, this complicates the algorithm and requires more changes…

Great project, I made your previous design and it was working fine, now that I modified the design with the new gyro plate the cube always slowly falls down as if the reaction wheels can't keep up. Same behavior when balancing on the side or on the corner, any idea what could be causing this? Also why did you remove the code to allow it to balance on all sides? Thanks!
@ReMRC 27 күн бұрын
Maybe the encoders are connected badly? Red connections in the schematic.
@sander368 27 күн бұрын
@@ReMRC Ah yes I got the encoder pins for the motors on my pcb design crossed so I just swapped the pins in software and now it works. Amazing upgrade, so much more stable and the wheels sometimes almost stand still. Is there a reason not to implement standing on all three sides of the cube?
@ReMRC 26 күн бұрын
@@sander368 Look at sensor orientation. :) In the first cube I didn't intend to do balancing on the edges. But I did it, although it works badly, and primarily because of the position of the sensor.
