is designing a pcb with multiple controllers a good schematic design?

Will it cause hardware problems? Theoretically, no. This is done quite often, so there is no inherent limitation there. If you design the board badly on the other hand, well that's just bad design! ...

RpLIDAR unable to see black objects

LIDAR sensors rely on sending out a pulse of light it hitting an object and then traveling back to the sensor to detect it. Black objects are often problematic because they absorb the light and not ...

Could a hot air balloon be powered from the ground like a drone?

The other option would be a laser. The baloon could reach migher altitudes without the corresponding increase in wire weight. Of course, it would need some means of holding position. Which it might ...
