Detect collusion

Hello everyone,

I want to detect when my drone collides an object. Is there a collision sensor or any other method where I can get when there is a collision?

I just want to get the data if there is a contact or not at some time. Would a Bump Sensor be useful or are there simpler ways?

If you're in simulation/gazebo, it should be relatively straight forward (using AABB collision boundaries)

In real life, I hope your drone never collides with anything ever. You'll likely want to have a lidar and/or depth camera for really good collision avoidance (and pair it with move_base). For smaller drones that have a camera, this is very difficult ..

Thank you very much for the answer. All sensors are helpful for collision avoidance but in order to keep track if there is a collision or not, should I use a collision boundary like gz topic -e /gazebo/default/box/link/my_contact ? I need to keep its data per time and save it as like in imu sensor dataset

What about the bump sensor? Can it be used too? Because I have difficulty in adding it to my model
