IDEA

I want to design and build a drone with LASER PROXIMITY SENSORS which will allow a drone to fly without hitting obstacles. It should be able to STEER AWAY from objects in its immediate path, whatever direction it is flying.

Sometimes the proximity sensors are really a mess.Instead,you can use ultrasonic sensors . The distance can be calculated using them and you can use it to steer the drone away from obstacles.

Thanks for the quick input. I was also thinking about SONAR NAVIGATION- the old school way, the way a BAT would navigate. But the addition of sensors will mean a microcomputer on-board (of course- for the analysis and reaction processes), and that would practically mean more weight, hence more power required to fly…?

You got it right,but it’s worth it.You could use a Arduino nano or equivalent as the brain which weighs 5 grams and requires approximately 5V to operate.
