Folks,
I need robotic kits that use the propeller chip.
Please provide web likns to your kit info.

meow, i have my own topic now? (sorta)
http://www.xtune.se/product_info.php?products_id=80
I am currently in development of another robot kit (this one based on the Atmel Tiny-2313) - my target price is about $25-$30 (US). I hope to be going to copper this weekend. Ever since the UPENE'09, I have been looking at developing a 'bot based on the Prop. I guess that I will get started on my Prop-based robot as soon as I get my current project sent off for the Beta boards to be printed.
This is what I am thinking about:
4 AA-cell battery pack with slide switch
1 PCB (probably about 2"x2" or so)
1 small proto/breadboard for user I/O circuits
1 Propeller with with a 32K EEPROM, voltage regulator, a serial port and a reset button
2 stepper motors with wheels for differential drive (good for keeping track of position through dead reckoning)
2 (or more?) servo motor interfaces (with maybe one small servo included)
4 (6?) digital input ports for bumper sensors (forward-left and -right, and rear-left and -right)
2 (3?, 5?) analog inputs with photoresistors for light/line following, photophobe, photovore, etc.
1 small speaker
(so far about 21 I/O pins - the rest would be available for user I/O circuits)
Target audience will be kids (mid-to-late teens) and up to students at technical-school/university level who have little experience in building electronic projects. The goal here is to possibly increase the number of Electronic Engineers entering college (more cool toys for us to play with as they invent new stuff
Target price should be around $30-$50 for the entire kit (may require some sacrifices/trade-offs)
Would something like this meet your needs? What additions/deletions/changes would you like to see? Remember that the price is going to be a concern (both for my customers as well as my development budget - I'm still a pretty small operation as of yet). Most likely the schematic and PCB artwork will be available for free download from my site and a kit of all parts will be available for sale there as well.
Let me know what you think, also, I would also appreciate any input from the rest of the forum.

James,
Well, first of all, that is what Phil requested at the beginning of this thread.
That said, though; that is a good question. Why would we want to produce a kit in this day when most people don't care about the "how",
they only want to be able to play, and they want to do it now!
Well, my purpose, or goal - like I said earlier - is to help interest kids in getting into electronics, or engineering or some technical field.
Techs are more interested in the "how" and a cool toy that they can "create" themselves, and which will do what they tell it to, is
something which will, I believe, have a great drawing power.
Lee Hart expressed it pretty well in his discussion/description of his Membership Card - a simple, low-cost, easy-to-build kit to produce a
computer, to get kids interested in electronics/computers. This is to be similar, but approaching the issue from another angle.

micro for kids to learn to program on.
I was thinking, assume the kid can get his hands on an old PC keyboard, an old analog TV, and a wall wart, and a mouse.
(All of this stuff is currently clogging our landfills.)
Give him a card with a Prop, SD card, and just enough electronics to hook up to those devices, and give him a reasonable
BASIC, a ton of prewritten programs on the SD card, and a book (like one of the Lamothe books).
The question is, how cheap can we build such a card (to make them throwaway), and can we get the software in a
reasonable state so it's usable?
I never completed this project because I was unhappy with the graphics I could make available and still fit an interpreter
in memory. But the state of the art in Propeller has advanced a lot since then. Hmm. Maybe I will resurrect this.
This robot really makes use of the Propeller chip. Some of the features we are adding includes stronger motors (with encoder feedback!), new stall detection, a louder speaker (we have removed the Consumer Product Safety Commission testing by designing/marketing this for adults, instead of kids), total backward compatibility with the Scribbler GUI, high-power ports on the hacker supply (> 1A), bi-color LEDs, major expansion to the hacker port, compatibility with the EPRE "Fluke", and a few more items I can't remember unless I look at the specification. This Scribbler will be red.
Two days ago the Scribbler team (less Phil Pilgrim) met at the factory in Asia to review the Scribbler 2 design and manufacturing schedule. We expect to see the first Scribbler 2 robots in summer 2010. Design started last June, however. I'd love to attach some photos but the manufacturer runs some big-time toys through their shop that we can't talk about.
We are really excited about this robot because of the improved mechanics, processor and wider market.
