01 / What it does

The project

  • A central body holds the electronics stack, with four separate bolt-on arms, so a broken arm is a reprint, not a new frame.
  • A ring guard around each propeller and a leg under each arm tip ending in a brass foot. The feet also carry the charging current from the Base.
  • ArduPilot on the flight controller, optical flow and lidar for position hold indoors with no GNSS, and a Raspberry Pi companion with a downward camera for precision landing.

02 / Why

What it gives Volans

Every other part of Volans exists to make this aircraft fly a mission on its own and come home.

03 / Plan

Steps and targets

  1. 01Frame CAD, drawings and checksDone
  2. 02Arm checked by hand calculation; first bending mode about 210 Hz vs rotor about 160 Hz at hoverDone
  3. 03Print, wire and set up ArduPilot with props offNext
  4. 04First hoverPlanned

Success looks like

  • Stable indoor hover on optical flow
  • Hover time of 5 minutes or more
  • Arm survives a bending test with margin
