Overview


Our product works on two basic principles — utilising ultrasound to detect distance, and limiting the control commands received by the drone.

Our Inspiration


Our anti-collision modular add-on mimics an experienced human pilot.

  • If your drone is about to collide with a large object, the usual reaction would be to simply adjust the joystick to change its movement and slow it down to a stop before it hits the obstacle.
  • It sounds like an easy task but executing it proves to be far more challenging.
  • Slight miscalculations on the user’s part could lead to disastrous consequences for the drone, its surroundings and the user’s wallet.

Our System


Our anti-collision system works by first having HILDA sense an incoming object. When a nearby obstacle is detected, HILDA will effectively alter the command sent by the user to reduce the speed of the drone, preventing an inevitable crash.

Think of it as a teacher snatching the remote control out of the hands of an inexperienced pilot, and taking over the control of the drone. However, with HILDA’s help, you can avoid the violent and embarrassing occurrence of having your remote control stolen.

Our Ultrasound Sensors


 

Using the same principle from sonar and echolocation, the ultrasound sensors on HILDA emit a distinct ultrasound pulse, and detects the time required for this pulse to return to the drone. Based on the time required, and taking into account the speed of sound, the distance of the obstacle from the drone is calculated. Such distance detection is crucial for HILDA to accurately determine the speed and degree of adjustment required by the drone to prevent a crash.
