Learning becomes easier when we add a little bit of fun to it. Here using the idea of obstacle detection, rather than just implementing simple obstacle avoidance in the drones path, I thought of playing a game with it.
To understand basic ideas of IR sensors and detection, I thought of building a game based on this using a drone. In this game of table tennis we can replace the ball with a drone.There will be 2 IR sensors on either sides which will detect a TT racket in its range and will move in the opposite direction thus 2 players can easily play this game.
For this, we require the RC roll to be OFF and for it to roll in the opposite direction by itself as given in the code. I have used PlutoX controller, which has its own open source Cygnus IDE on which I implemented my code.
- PrimusX board
- 2 IR sensors (V53LOX)
- Breakout board
- 600 mAh batteries
VCC is connected to BAT pin.
- The IR sensor that I have integrated consists of five connections, namely VCC, GND, RESET, I2C pins SCL, SDA.
- The breakout board provides I2C connections.
- Pin 6 to SDA.
- Pin 7 to SCL.
- Pins 13 & 15 are the default pins for getting range from IR sensors using Xshield API, which is connected to pin X on the sensor module.
- Breakout board gives the range from IR sensors.
- If an obstacles are encountered within 150mm, the drone moves in the opposite direction.
- Using IR sensors on both sides a drone can be used to play table tennis.
