Current working on a project with the following and would appreciate if someone could assist in the following:

1. Object will be airlifted by a RC helicopter
2. Will move to a red target object
3. RC helicopter will release the object
4. Object will activate the CCD Camera with red colour detection system (Remarks: having difficulty to source for such hardware and software to resolve this problem)
5. Using the error correction method to move the actuator so as to hit the red target.

You'll have to be MUCH more specific before anyone can help you.  What do you need help on?  Are you encountering any specific problems, or are you in general unsure of where to start?

Also...that project seems really hard, so I'm going to assume you're a university student or working for a company of some kind, or are a REALLY enthusiastic amateur and have signed up for a competition of some kind?

Sounds like you're building a color guided bomb. :D :D

How exactly is the "object" going to self adjust when it's already been dropped?  Does it have wings or a tail rudder or something?

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

Hi Mstacho,

Yes you are right, I am a current university student working on the project, the project should be able to enter competition depending on the progress. Hope you guys are able to help me with the details below:

1. Object will be airlifted by a RC helicopter - For information only.

2. Will move to a red target object - For information only.

3. RC helicopter will release the object - For information only.

4. Object will activate the CCD Camera with red colour detection system
Remarks: Having problem to resolve this issue in terms of defining the hardware and software. What types of camera to be use and should I use software to do the colour filtering and select the specific colour? Any programming language and codes to share? What types of microprocessor should i use in this case?

5. Using the error correction method to move the actuator so as to hit the red target.
Remarks: The object will be fitted with fins and actuator to rotate the fins for move the object to the target. There should be software code to do the programming to correct the current position to move to the intended location and moving the actuator angle accordingly. Having difficulty to define the programming code.

Well, the best I can do is give you a start (and hopefully others will chime in as well!)

#4 is pretty broad.  Camera can probably be something as simple as a webcam -- all you're doing is identifying RED, so it's not like you'll need a massively expensive camera.  I'd use OpenCV, a computer vision suite, but if you do that you'd be pretty limited to something that goes beyond the idea of a "microcontroller", so it might depend on your budget.  Other people on this forum have been talking about using the Axon microcontroller along with a "blackfin" camera, but I have no idea what that is :-P

#5 is really hard, and you'll need to give us more information.  The control should be simple enough, but if the package is only dropping a few feet onto a small target it'll be way harder than if it's dropping 100 feet onto a large one...

I've never worked with "robot vision" but there are a lot of threads on this site about it.  Just search for "robot vision" or "camera" or "color tracking".

I FINALLY understand how #5 is going to work.  The fins will act as rudders to steer the "package".  Ah whatever, I'm calling it a bomb, it's much more fun that way.  It'll have to be moving pretty quick if you want rudders to work right?  

Here's a page (on this site) that you'll be interested in.
