Today I got an interesting question from a student about how to run a Litchi mission and be able to reverse it halfway and then reverse again and continue. Below you will see the email from the student and then my answer. I hope it helps you with your missions...
I was wondering if I had a 10 waypoint mission. Can I fly waypoint 1 & 2, stop recording at waypoint 2, go to waypoint 3 which is at a higher altitude and 300 feet away from waypiont 2, turn and aim at POI 1, snap a image and fly back to waypoint 2 and resume recording at waypoint 2 and continue with my mission?
Is this possible with Litchi? Your reply would be mostly appreciated.
Yes there is a way. Set the cruising speed to 0 and the max flight speed to whatever you want as the fastest. Set finish action to Reverse.
Then run the mission. The drone will sit still. Push right stick up and it will start moving to WP 1. You control the speed. Start recording at WP 1 and when you get to WP 2 take your finger off the stick. You will stop moving. Stop recording. Then push the stick up to continue to WP 3. Aim at the POI and use the shutter to take pics. Then pull the right stick down to go back to WP 2 and start recording. If when you get to WP 2 you want to carry on the mission at a set speed then open the mission settings and set the speed slider from 0 to whatever it is you like and that way you don't have to control the speed.
Remember to disable your heading to user controlled/manual and gimbal to disabled if you want the ability to frame the shot exactly
