##### Rocket tracking using pythagorean theorem.
« on: June 27, 2010, 06:52:57 PM »
I would like to build a robot that can track a rocket (most likely no higher than 175 meters) and based on angle at its greatest and the launch location calculate approximate height. I would like to know if this is possible if I don't want to spend more than \$125 USD on any one component of the robot. All of the above with the exception of the last sentence are tentative and are just the first thing that I thought of. This is not the only task I would like this robot to perform if that makes any difference. If you have any suggestions as far as a better method to find this number using a robot I would appreciate any suggestions. I am new to autonomous robots but have programmed in c++, basic, c# and python. I am looking at using this project board:  PICAXE-28 Project Board and this microprocessor: PICAXE-28X1 IC. I have very little experience with homemade robots but I am willing to spend a while on this project along the lines of years if necessary. Lastly if I am posting in the wrong part of the forum let me know. Thanks.

The hard part is, how does the robot track the rocket?

I'm thinking a little device that you input the angle into and your distance from the launch pad would be a lot easier than having to track a teeny little dot in the sky.

Possibly using the exhaust trail and tracking using IR or maybe a something that can analyze color and identify the rocket based on that. The problem I would guess with both of the above ideas is the cost. Any suggestions would be appreciated. Thanks.

Hi,

A rocket gets very hot at the bottom. Heat = IR.
If you don't point it against the sun or close to, you might be able to track it by it's IR signature.

Perhaps see if you can find any info on incoming missile warning systems as used in fighter jets.

A rather fast and fairly heavy robot with quite large wheels needs what? A lot of power?
