tracking a target

Hi guys, Could any one suggest me how to track a target . I think we cannot interface arduino and web cam and track down some object using opencv. Is the target tracking possible through antenna. Has any one done antenna tracking robot. Suggestions please. Thanks in advance.

YES

do you mean a beacon ? do a google search for rf bracon or ir beacon what ever you prefer

Define 'target'.

My work is on path planning. Where a mobile robot should move from start and track a target in obstacle bounded environment. Target can be any thing. May be an antennae or some red coloured ball(if it can be detected through web cam).

well from some of my previous post's i realaised a target acnt by something or anyhting so that dosent answer the question

(if it can be detected through web cam).

it cant be done

tracking in general means detecting a moving object if the object is stationary you could use the word detect detectin is a lot different from tracking and would effect the design of you bot

No, you still haven't defined target. What physical property are you going to exploit to detect and track it, at what range, how big it is with respect to the environment, etc?

So not only does this robot have to know where it is aiming it also has to detect obstacles and avoid them. This sounds a way too big job for an arduino by several orders of magnitude.

Google and robotic forums are your friend for researching your project. If you are allowed to define your target, make it an IR LED. You will first need to study how to perform the "detection", then how to perform the detection over and over again in a dynamic environment. If your target can "hide" behind obstacles then the detection will be very challaging. Research the simple line following bots and bots that run thru mazes for starters.

There are several ways to connect an arduino to an iPod Touch/iPhone. The latest iPod Touch and all iPhones have camera's built in, and very capable CPU's on them. You might be able to use the iPod to do the tracking, and simply drive the arduino as a slave.

I’ve been tinkering with this a bit. Here’s how I’m approaching a similar project. You can do some basic color blob tracking in Processing so… Think of an Arduino based obstacle avoiding robot receiving course “suggestions” via it’s serial port from a Processing sketch where the analytics are happening. You can get a netbook and a webcam these days for under $200. The Arduino is plenty capable of running a PING, a GPS, a digital compass, a motor controller and a pan servo. What you can accomplish these days for under $500 is mind boggling!
