Has anyone had a good look at the diagram that is in the
Tello manual or on the
Tello advertisement on the Ryze Robotics web site?
If you look closely you will see a “Collision Detection” label description on the
Tello diagram.
I’ve attached a screenshot of this diagram and circled it in blue.
Does anyone have any idea as to what Ryze is referring to?
I don't think it's obstacle avoidance, like some of DJI's other drones. I've experimented with the
Tello to see if it will try to avoid an obstacle. As near as I can tell, it doesn't. It DOES however shut itself down immediately if the IMU detects a sudden, unusual movement. Whether that's a good idea depends upon the situation the drone is in. The first day I had the drone I crashed it, and two of the props were sling-shotted (is that a word?) across the room. Without thinking, I put them back on without checking to see if I had each prop on the correct motor. I didn't. When the drone started to take off on the next flight, it lifted on one side to about 45 degrees. As soon as the IMU detected that unusual motion, it shut off all the motors. A little muttering, then a forehead slap, and I got it straightened out. The
Tello will recover from minor collisions and keep flying, but if you have a good hard hit, it shuts down. So far, I've been flying with the prop guards on (I know how I am), which help a great deal. I've managed to put a divot in one prop, even so, which makes the prop significantly louder, but there's no other apparent effect.
