New robot for Scratch
I made it possible to control a robot named "MYUROBO" from ScratchSource 1.3.1.
MYUROBO is a kit sold in Japan about 2500-4500 yen ($30-40).
http://www.studiomyu.com/myurobo/
It's expandable and easy to use from some languages. BASIC, DOLITTLE (a kind of Object Oriented LOGO) and Assembler.
Here is a zip file that includes image, sample projects and others:

And a screenshot is here:

You can find additional blocks in motion category of stage.
This image includes joystick extension it enables to use typical gamepad too,

Re: New robot for Scratch
Very cool! It looks somewhat similar to the WeDo feature in that it uses a tether. But the price is much more attractive.

Re: New robot for Scratch
Nice! Looks great. I think Scratch offers a lot of possibilities for robot control, if we can just get the interface to the real world simplified a bit. I'm also looking forward to playing with the WeDo eventually...

Re: New robot for Scratch
Thank you all.
There are many reason of Scratch's success, easy to use, sharing idea, and etc. I think one important reason is free to use.
As we know, physical computing that interacting with real and virtual world is very interesting. Unfortunately, no hardware devices are free. WeDo is a great one. I love it. But it's little expensive for kids. ("I can't buy it with my pocket!")
So we need more cheaper and primitive devices, I think. MYUROBO is an example.
BTW, I attached a webcam to my MYUROBO.

Here is a movie taken by it.

It's very fun! If ScratchSource 1.4 is released in the future, we'll be able to do many things with it.
Best,

Re: New robot for Scratch
Hello, Abee
Control "MYUROBO" using Keyboard and Joystick is fun!. I think "Controlling Robot using Keyboard and Joystick" is good start to program autonomous robot or physical computing.
I agree your opinions about cheaper and primitive devices. It is importance to children and educational point.
In Korea, PicoBoard does not sell in shop. If sell the PicoBoard, It's expensive due to import charges and extra. So children need 'localization' and 'open source hardware'. For example, GoGoboard(http://web.media.mit.edu/~arnans/research.html#research%20projects) and Helloboard(http://scratch.mit.edu/forums/viewtopic.php?id=16823).
Abee, I translate Rtoys (http://squeaksource.com/Rtoys.html MYUROBO programming library for Etoys) to Scratch1.3.1. But It works only Smalltalk not Scratch Block. I'll study your "MYUROBO extension" and I adapt It. B-)
This is screenshot.

Re: New robot for Scratch
I can't really figure out exactly what the myurobo includes, since I can't find an English version of the specs, but (and abee can probably correct me) it looks like a microprocessor (PIC16F688, I think) + motor controllers for 2-4 motors + a usb interface + DC motors. The price is pretty good, if that's the case, because if you were to make this with Arduino and a motor controller shield, it would be quite a bit more expensive. Of course, the Arduino has a large number of inputs/outputs.

Re: New robot for Scratch
Hi, chalkmarrow,
Your explanation is almost correct. User can choose PIC16F630 or PIC16F688. PIC16F630 is cheaper but limited functions. And an USB-Serial converter cable is not included in a kit. But PicoBoard's cable is usable for it.
Arduino's AVR chip is more powerful than PIC. And there are many users, examples and applications for it. But it's a little expensive as you said. We should choose devices by the purpose.
Cheers,

Re: New robot for Scratch
Hi, dongheepark
Wow, what a quick job! I think wrapping your Smalltalk code into Scratch block is very easy.
BTW, did you check the following page?
http://info.scratch.mit.edu/Sensor_Board
PicoBoard is able to make at very low cost. One Japanese guy did it with a bread board.

Re: New robot for Scratch
Thanks, Abe.
I'll try to make scratch blocks. My code of MYUROBO library is not clean. If you have a propose, I love it.
I checked Sensor Board. In scratch day 2009 in SEOUL, Ho-jun Song made Helloboard that is clone of Picoboard. Check this thread.
http://scratch.mit.edu/forums/viewtopic.php?id=16823
In scratch day, Ho-jun have a take about "Sustainable Open Source Hardware Project" that is issue of making Helloboard in Korea.
This is slide of Ho-jun's speech.
