so it stabilises the weight to stop it swinging out by flying sideways with the mass and slowing down instead of stopping, but this does nothing to help in any situation where there is a risk of the load hitting something, as the lateral movement of the load seems to be the same, if not actually increased in comparison, the difference being, now instead of just the load hitting whatever it is moving towards, the drone does too, as the drone is moving with the weight
this seems great for stability, say if you are in the air and have to make a sharp turn for reasons other than large obstacle avoidance (although i cant think off hand what that reason would be, unless your flying in supplies to an active warzone and had to dodge bullets and missiles? or deviating sideways to miss a flock of birds? although even then, without stabilisation control, the payload is just going to be swinging out into thin air, so is it really an improvement unless the payload is highly orientation sensitive?)
ultimatly, from the video, it looks like a maybe 20 degree less pendulation, in exchange for the drone drifting sideways of its own volition, and im really struggling to see real world applications for this, as i cant think of any payload that would be happy with the 10-20degrees it still produces even with the stabilisation, but not the 45 it creates without, and i can see lots of situations where unasked for drone drift would be as if not more dangerous than the payload swinging
edit: id be interested to hear of anyone who can think of specific case usage where this would be noticeably advantageous?
