The project is an audio idea i progressed from my visual Picaxxo project.

To get him to tidy as quickly as possible i had to install the boredom/patience routines.
He keeps a track of the number of repetitive actions, if he makes more than 20 repetitive actions then he kicks in his "lets do something else routine"
The colour detect is good for 8 colours - the sensor has a double purpose - it checks the distance to object as well...

Yes when you include the environment that the "Bot" moves around in there is a lot of "Fuzziness" - it gives character - nothing is perfect.
"Expect the Unexpected"

Thanks ......It was a cool programming project to undertake - with lots of candle burning hours and hair-pulling to boot.......

This is the latest Autonomous programming project i am working on - using an Arduino Mega compatible.



The full details can be seen here at http://letsmakerobots.com/node/21048
The three videos here show my programming progress from start to finish.
All videos show him in Autonomous mode.

[GP2Y0A02YK0F]

Updated using :-
Sharp GP2Y0A02YK0F  Long Range IR sensor - mounted vertically.

Compared to the Ultrasonic, i must say that the results are much cleaner.
This sensor will scan up to 150cm (tested).

Recommendation would be to use "Processing" as it lends its self to serial data and also Graphic Visualization so at least you can see what is happening.
At present i am experimenting with Making Robots with Senses (the project you see here is "Sight") which will be autonomous ie no external PCs.

Thanks for the Data.
I have since turned the Ultrasonic into vertical alignment and improved the results. (it will work up to 4 meters at solid wall - soft objects reduce the efficiency and echos bounce-ing of objects can interfere )

The Servo is in slow mode at the moment - just for tune-ing . I am expecting it to go 2 or 3 times faster.

To get more accuracy i would have to mount it on a digital servo (ie more in-between steps)

Thanks for the link - i have admired your 3D system for a while now :o.

Yes the project is only a few days old and its only now that the true ultrasonic scan data is visible on the display.

The Ultrasonic footprint of an object is quite wide (wider than i had calculated) - and yes i will be probe-ing an IR sharp for comparison soon.

The plus point of Ultrasonic system is its scanning range - however the "extra" echos can be miss-leading.

"LoMoR" - Lets Orientate & Map Our Robots (Sonar Based)
Here is a Sonar system i created by combining
an Ultrasonic Measurement Transducer with a Scanning Servo,
mapped onto a (X,Y) LCD Display.

Nice one Captain - its amazing how few components are really needed to get these babies running.

Contest close date delayed until 5 July  :o ..... tension is building for the results.... join the action on http:// http://letsmakerobots.com/taxonomy/term/3546

Hallo Captain ------ cool to link up here too.

The arduino site is a must for me and full of super information.
Look forward to see your posts both here and of course the amazing LMR site.......
