Building a quadcopter 5HC99 Group 3
Outline ● Hardware ● Software ● Tuning ● Video ● Demo
Hardware ● Standard frame ● Two Raspberry PI's ● Two camera's ● Barometer ● Battery alarm
Raspberry PI ● Two Raspberry PI's ● Communicate using ethernet ● Wlan for communication laptop ● USB to stm32f3
Connections
Hardware problems ● Battery died – Leaving it for a month mostly fixed it ● Bad ESC – Thanks Emilio for a replacement
Globalcontrol ● High level interface ● Connect Raspberry PI to STM32 ● Communicate using UAVObjects ● Containing data and settings
Globalcontrol applications ● Record video when armed – Other conditions also possible ● Attach barometer to Raspberry PI – I2C didn't work on STM32 – Raspberry PI sends the data to STM32
Face detection ● Face detection using Raspberry PI camera ● About 4 fps ● Marker detection also possible ● But not finished
PID Tuning ● Took a lot of time! ● Problems: – Motors rotating in wrong direction – Bad ESC – Easy to break the frame in the process ● Lots of trial and error ● Quite stable now :)
