Microcopter with barometric attitude stabilization  Tweet

In my last article I talked about Holger's Microcopter which uses a barometric sensor to measure air pressure to stabilize it's altitute. You can imagine that air pressure only differs minimal between a place 1m higher and another place 1m lower. So the sensibility of the air pressure sensor has to be very high to be able to recognize small altitude changes.

Such high sensibility has it's pitfalls and it seems to be fun to test them out. Holger found out that opening a door while flying indoors already results in such a big air pressure change that the Microcopter would race through the floor or roof if the linear acceleration sensors would not compensate!

Holger released a new video showing his indoor experiments...
