Testplan - to be filled out by requesting team

Test 1: Test Basic Obstacle Avoidance

Procedure

Goals / Objectives

Knockoff Criteria

  1. Set waypoints

  • Create a simple path for the drone to follow.

 

  1. Run main obstacle avoidance script

 

 

  1. Set up the obstacle in course

 

 

  1. Battery plugged in

  • Mission planner no pre-arm warning

  • make sure AUTO is in one of the flight mode

 

  1. Bring the drone to the flightline

  • toggle safety switch

 

  1. Enable logging

 

 

  1. Arm the drone in AUTO

 

 

  1. Let drone start flying through waypoints in AUTO

 

  • Drone unstable

  • unable to establish VLOS

  • Timer threshold:

    • flight time exceeded 5 min.

    VBatt below safety threshold: 10V

    • QLAND immediately, disarm when landed.

    • Recover drone & gather state of batteries

    Lost link

    • Follow lost link procedures. Maintain vlos if possible.

    • Contact necessary local authorities.

  1. Wait for drone to approach the obstacle

 

 

  1. Ensure that drone stops and enters LOITER mode when detect object

  • Ensure the drone stops ~10m away from obstacle.

  • Ensure drone switches to LOITER mode upon detecting obstacle.

If the drone does not stop within 10m of the person and obstacle:

  • The person holding the obstacle steps out of flight path immediately.

  • Pilot manually intervenes and skips to Step 13 (landing and disarming drone).

  1. Remove the obstacle from the flight path and ensure the drone reenters AUTO mode

  • Ensure the drone resumes its mission.

  • Ensure drone switches to AUTO mode upon obstacle removal.

If drone does not resume to landing waypoint

  • Pilot manually takes over and proceeds to Step 13 (landing and disarming drone).

  1. Drone hovers over the 2nd waypoint (the landing waypoint)

  •  Ensure drone completes the mission.

 

  1. Pilot manually lands drone

 

 

  1. Disarm the drone

  • disarm the drone, Toggle safety switch

DEBRIEF

  • Wanted to fly the drone and do obstacle avoidance

  • buck converter for RPi usb c port broke off

    • was untested

    • known issue with these board with respect to poor solder

  • Collected lidar data on the ground to develop path deflection algorithm

  • Moving the drone is on pace for two weeks from now

    • added deadlines into asana for some of this
