Hi - thanks

Yes the boards been pretty good. Bit worried it gets warm so I may drill some ventilation into the box to get airflow

The boot time is pretty good (5-10s) and openwrt has everything you need. I'm keeping my matrix size down (32x32 or smaller) and frame rates low 1-5 fps so the performance is fine.

Great for experimenting with and a real big improvement to basic robobuilder - The 3D printed case and power lead and serial converter turn it into a really nice package and with a servo mounted webcam it really becomes a cheap (hobbyist) "Darwin" or "Nao".

The only downside is really the memory/disk, after building OS you have about 4-5M free which means installing perl/python or java would be difficult. I have GnuOctave (open source Matlab) built but at 5M it doesn't quite fit. I could use the USB slot for memory stick but then no camera or would need a hub.

The tool chain is easy to use as well so building C programs is a snip. This is why I've been playing with my RoboBasic - at 40K download its much smaller than the big boys but gives me complete control over the robot and now some basic image processing. I've also created an alternative to the IDE using awk that runs on the omnima so I can generated the binaries from txt files edited with vi.

Next up I should have the ball tracking video done using a simple colour filter. I'm still playing with Guesture recognition - but that is basically working (on test images) and then I have some convolve kernels to play with edge detection ...

Very nice indeed!

It looks really cool.
Btw how is the Linux board holding up? Has it been up to the job?

Regards
Pedro

Hi l3v3rz

This is quite an impressive work. Really nice

I can see you implement interesting Vision Algorithms in this latest version.

Would it be possible for you to make a Video of the Vision Samples you posted on the Wiki?
Your Wiki is indeed very good, but the Vision part/algorithms, I must confess are still a bit obscure to me.

Regards
Pedro.

New version uploaded - see web site
http://code.google.com/p/robobuilderlib/

Main focus has been on Linux and Omnima version which now supports IMAGE processing. The new functions enable BASIC to load jpeg images into arrays and either filtered or grey scales, The image processing has been based on CMVision library and enable user to create multiple colour threshold maps and then blob detect areas.

The IDE has had an Image processing tool to help create filters and check their effect.

New extended commands:
http://code.google.com/p/robobuilderlib ... edCommands

Image processing demo's
http://code.google.com/p/robobuilderlib/wiki/ImageDemos

And a simple gesture recognition example
http://code.google.com/p/robobuilderlib ... ecognition

The new Firmware version is also available includes (since 452)
1/ New 'p' option - set all servos passive
2/ Q option - queries all servo values and displays result
3/ Bug fixes to edit lines
4/ New options on SCALE command to enable threshold
5/ New options on LIST to support stacks and hence Procedure and Functions
6/ New List functions $SHUF and $MAP
7/ New List operators '+' '-' and '.'
8/ Bug fix to expression handler and Cos function

1) Adds new ON TIME and ON KEY functions.
2) FIx for the expression handler
3) Improved Basic IDE with better error messages
4) Updated manual

http://code.google.com/p/robobuilderlib ... V2.2.2.pdf

New version of firmware and windows build now available. (v423)

1/ Adds improved list handling making programs easier
2/ reduce memory footprint so should be more stable

Also a small update to BasicIDE now v415

New BUILD 408 out. The expression parser has been heavily updated and now supports:

1. Operator precedence . i.e PRINT 3*5+4*6 now prints 39 (not 87!)

2. AND, OR and MOD are supported i.e. PRINT (1=1) AND (2=2) prints 1 (true). The old | % & still work as well

3. Complex expressions now work such as (from dynamic gate demo)
30 LET P=@B[Y]+@A[Y]*$SIN((X+@C[y])*16)/32768
Before this had to broken up. So this also will be faster

4. expression use 32 bit integer arithmetic - previously it was 16 bit, this make the range much better for complex expression - like above

5. Its not trashing memory! -> this was causing OFFSET array to be overwritten causing all sorts of problems with MOVE function.

6. There's a new variant of MOVE command the uses the ! array so it works well with GEN command (to evolve new positions - example coming soon)

7. Versions for Linux and Windows now has floating point (in test mode). Also have built Linux version for OpenWRT - seems to work OK.

There's also new version of BasicIDE that fixes a bug with nested IF/ENDIFs

New version of the Basic manual now available. Its considerably expanded over the original with lots of programming ideas and new examples

http://robobuilderlib.googlecode.com/fi ... 20V2.2.pdf

Some of the examples require the latest firmware now at Build 390 which has some "Basic" neural network and genetic algorithm features

In other news I now have the linux version as a opkg package that runs on MiniEmbWifi. Next task is to get it communicating with RBC running DCMP firmware. Long term I may build some video processing features into it as well (if I can get my webcam running)

I've fixed the com port selection and uploaded the new version v389. It was by default trying my com port first Added a pick selection as well if you have multiple ports

I'm glad you find it fun - that's what I'm trying to achieve - to make programming robobuilder as easy as possible - rather like in the early days of the PC programming on Acorn or ZX80. In fact the power of chips is comparable.

I had a little time to play around with the updated basicIDE, and discovered 2 things, (robobuilder is on com7) When I go to conenct it says it can not open com7, So i loaded some code anyway and compiled it, clicked download and it worked fine, dispite the cannot connect error.

Thats great news ! I will do some programming/hacking on the bot sunday night (work all day on sat) everything is working great. I have almost all of the project files and docs downloaded. Im not sure if this is helpful but , I have 2 websites if you ever want to use some of my space on one of the sites to mirror the files i can do that. One of the things I was going to do is I wanted to combine the auto balancing program with the continuous walking, I was thinking when he goes from walking to just standing it runs the auto balance subroutine. Might be good for fighting like when the other bot hits his arms go forward to balance him and keep him from falling. Just a thought. Thanks again for this sweet project, I have not had this much fun programing in years and like I said it bring back my coco days, and BTW i still have all that trs80 stuff in a room in my cellar in perfect working order. Cheers !
