Terry,

I have, perhaps, just the thing for you! I have been working with some colleagues at the Institute for Personal Robots in Education (IPRE) on a robot for just such a course. I didn't mention this one in my original message to William (included below for those who are interested) because it is a very different niche than the Aibo, but nice for CS0, CS1, and maybe even CS2.

The basic idea is that we make engaging robots cheap enough so that every student can have their own. We hope in the end that they will cost about $150, but we are closer to $200 right now. But, the pieces are mostly off-the-shelf. Here is what we currently have:

- the hardware
  - Scribbler robot
  - retails for about $80, but discounts for bulk purchases
  - 2 light sensors
  - 2 IR obstacle detector
  - 2 IR line detectors
  - stall detector
  - bluetooth wireless
  - plays tones (up to 2 at once)

- the software
  - called Myro (based, in part on Pyro)
  - written in CPython
  - simplified for CS0, CS1
  - adaptable, open source code
  - modified IDLE
  - runs on windows, linux and mac

- the materials
  - in progress
  - written in a wiki, add your own pages
  - real textbook is also planned

The best thing about the materials is that it incorporates more than just robotics. We have art-based lessons using the Scribbler's ability to draw, we have music-based lessons using the tone generator, we have an Instant Messaging library, for exploring communications, etc. Of course, all of these activities do involve robots (for example, you can send a command to a robot over the IM) but they involve activities that make the robot more than just a remote-controlled toy.

Our plans are to support as many robots as we can for educational purposes (including all of those mentioned to William: Hemisson, SRV-1, ePuck, Roomba, Lego NXT, etc), and make an easy path from Myro to Pyro.

You can find a picture of the IPRE robot kit here:

along with more details of the entire project. You can read a brief description of the IPRE and the project here:

http://wiki.roboteducation.org/wiki/index.php/Appendix

and find out more about the IPRE here:

http://www.roboteducation.org/

Of course, I'd be glad to answer any questions. (There are also related workshops at SIGCSE in a couple of weeks, at AAAI Spring Symposium in a month, and more events this summer).

Take a look at see if this would work for your needs. We can also offer assistance for getting started, and help on behind-the-scenes setup (how to teach such a class).

Doug,

I have just become a pyro-users subscriber. I saw your posting to William
Yu about possible robots. I went to look on the web and got info about the
ones you mentioned. I have prices but many of the other criteria I have
are not listed there.

I am buying a robot for use in a CS-0 class (in case you aren't familiar
with that notation this is called a breadth-first computer science class -
in this case many of the students are not very technical.)

The students are learning Python and will be somewhat proficient with it
by the time we get to the AI section.

I am hoping you might help me figure out what might be the best robot for
my criteria. Here are my criteria
  < $1000
  battery powered would be nice.
  can use Python to program it.
  able to have a wireless card or an onboard interpreter and RAM/EPROM
  I assume some sensors so that the robot can naviagate a maze or follow a
line

Also, I am wondering if I sent this correctly so that it is seen by other
members of the pyro-users group.

Terry

William,

This is the $64,000 question!

Unfortunately, there is not a $64,000 answer. The answer will really depend on the details of what you want to explore, what you value, and how much money you want to spend.

There are pros and cons to all of the following options, and maybe other will have their own opinions. But, here are some options (all of these have some type of vision, and either work with Pyro, or soon will):

1. Roomba, from iRobot. This option is quite cost-effective, and with some clever thinking, you can do a lot. I really think a modern robot has to have a camera, and you can put a laptop with a webcam on the roomba. My roomba is in the mail, so I can't personally can't comment yet on the recent additions to Pyro by James Snow that allow Pyro to control the roomba. (James's code looks excellent, though!) Also, Pyro's vision code currently only works under Linux. This isn't a self-contained robot though, so it will take a little work to get the laptop, software, webcam, and needed parts.

2. ePuck, from GCtronic. I'm just starting to test this out. It is a little pricey and small, but looks like a nice challenger to the Khepera, if you like desktop robotics. Pyro support should be easy (may use the exact same commands as Khepera, which is already supported).

3. Hemisson, from K-Team, and RoadNarrows. A little pricey (once you add all of the needed attachments) and is missing odometry (which the Aibo never had). The vision is done through a separate wireless analog connection. I have had issues with dropped connections, but I know Kim and Robin have been working on this for a couple of years.

4. Surveyor SRV-1, from Surveyor.com. I don't know very much about this one, but it looks like it might be able to quite a bit. I have one of these in the mail, too, so I'll know more in a week or two.

5. AmigoBot from MobileRobot.com. The smallest and cheapest (but still pricey) from the company that produces many robots for research. It can play wav files, has a wireless camera (like the Hemisson), and uses the standard MobileRobot interface. Pyro should work with it through the Player interface. I haven't had one for 8 years, so others might have more to say.

6. Pioneer from MobileRobot.com. The standard in research robotics. Very pricey, but very flexible. Comes in a variety of options (indoor, outdoor, PeopleBot, gripper, etc).

There are some other options on the horizon (few months off), and this will surely be a topic at both AAAI Spring Symposium, and at SIGCSE.

Any other ideas?
