I have written my own coding and got the output in serial terminal window in Program editor for the PART III GET A GRIP. my problem is that how i can differentiate a cup from other object and make the robot understand it. kindly help me i searched the website but i was not able to get it. kindly help me with the code for " how i can make my robot understand that its a cup in front".  i am using PICAXE 28 and SRF005

Hi, First of all, when I

Hi, First of all, when I kept asking you to post on the project page, when you wrote me by mail and kept on messenging me, you should not post on a seperate forum topic, but as a comment / question on the project page.

Secondly, I’d like to help you, but it is really not possible. You provide a lot of code, and the description of what you’d like as “kindly help me”. It is impossible to solve your problem, when I do not know what it is.

The only thing I can say is; Break this down into very… VERY small bits, and make them work - one at a time.

Once you can document to us that you can scan with the SRF05, and that you have a working version of the project I described (I know I made a full walk through some place, please look for that) - then let me/us know excactly what DETAIL in the project you have a problem with.

Best of all, you should go ahead and try and make your own projects, I think you’d be far better off, and learn a lot more :slight_smile:

Best of luck.

I would think that object

I would think that object recognition is almost impossible with at ping sensor and a PICAXE. For that you would need a sensor with much higher resolution and something more beefy than that PICAXE.

By looking at your code this would probably be fare beyond your current programming skills.

(you’re doing stuff over and over again, but not a subroutine in sight…)

So take fritsl’s advice. Start with small steps and write some code that works, then build on that.

Small steps…

Your questions should not be general.  They need to be specific, otherwise they are too difficult to answer. 

How can I differentiate a cup from other objects and make the robot understand it?

This question needs more detail…
What other objects ?  Any objects? (that would be tough - OpenCV & webcam would be a guess, and this is on a visual level…)

OpenCV is not the only way… there are many ways to differentiate a cup from other “objects” … it depends on what is important…

How does a blind person differentiate a cup from other objects?  

Your robot is currently blind, but can ping…  So you have a kind-of echo measuring stick…  If you know where your ping sensor is & you know where you are pointing it, you can begin (with a lot of work) to measure things…  When you can measure things, you can find the dimensions of “object” (after a lot of work)…  With more work you can try to program something which scans for the dimension of an object which might match a “cup” …   This is after more work…  It will work like crap, but then you can put filtering on it (more work)…

OR you can control and simplify the environment, by putting the cup in a specific location - and the ping sensor only knows if the cup is there… or if it isn’t  (much easier) :slight_smile:

When you begin to ask yourself these questions, you can start trying to solve all the problems that are important…
