Steper driver dual axis camera motion controller
Project to make a motion capture dolly for video footage. Originally designed for timelapse motion, it is also suitable for automatic motion in live recording (interview backshot etc).
Processor is a Heltec Wifi32 Kit. Driver boads are drv 8825.
Dual axis control by stepper motor (1 for linear motion, 1 for rotary stage) Control is via roboremo App on phone.
Control philosophy is to set start and end points and a time. Camera motion then runs, interpolating between the two points.
