Bin noch nicht dazu gekommen ihn mir näher anzuschauen, aber der iRobot Create (www.irobot.com) sieht recht brauchbar aus und ist ziemlich preiswert. cu andreas ----- Original Message ----- From: metalab-bounces+andreas.trawoeger=wgkk.at Sent: 21.02.2007 08:24 To: metalab@lists.metalab.at Subject: [Metalab] Robotics Hallo Robotics-Gurus, ich suche für meinen 10jährigen Sohn und mich Robotics HW für Einsteiger. Ziel ist, eine Entwicklungsumgebung unter Linux verwenden zu können. Hat jemand Erfahrung diesbezüglich, was kommerziell verfügbare Lösungen betrifft? Ich hatte da an die Einsteiger-HW von Conrad gedacht: Robby RP5: http://www.conrad.at/goto.php?artikel=190333 Das Ding kann zumindest über serielle programmiert werden -- Basic schreckt mich allerdings eher ab. Dass man zusätzliche Prozessor-Board erwerben kann, lässt mich hoffen, dass man da dann für die Steuerung überhaupt was CPU-mäßig leistungsfähigeres anschließen kann. Ein Gumstix wär cool... http://gumstix.org/ und dann die Programmierung in Python... Hat jemand mit der konkreten HW schon Erfahrung? Wird abgeraten? Wisst Ihr was besseres? Im ersten Schritt möchte ich *nicht* anfangen, die HW selbst zu bauen...

Macht natürlich optisch nicht so viel her wie er von Conrad. In was werden die iRobots programmiert? Was ist das dabei? Hat wer schon Erfahrung? Ralf -- Ralf Schlatterbeck email: ralf@zoo.priv.at FAX: +43/2243/26465/23

If anyone is ordering iRobots, I'm in for one as well! These things are quite robust, high-quality and reasonably priced for what you get. They should be quite hackable as well, but they use a relatively weak Atmel microcontroller, so you don't want to install Linux on it. Attaching a Gumstix to it and talking to the robot in real-time over serial/USB should be easy though. ~/= Marius -- We are Elektropeople for a better living.

I'm thinking about buying a bunch of them (probably about five) for quite some time. So if someone else is interrested too, we could order a 10-pack: http://store.irobot.com/family/index.jsp?categoryId=2591511 But they are sold without batteries,control module and any additional goodies. So altogether you end up with something like 250$ per robot. cu andreas

Have you looked into sensors/actuators the device comes with and what you can add? It doesn't look very hackable to me concerning the hardware but I may be wrong... I'd like to use a robot to be able to do the robotchallenge courses, so I'd need some sensors to navigate on a line and get around obstacles etc...

They say that it ships with 30 sensors, although I cannot easily find a specification detailing these. Regarding hackable hardware - this might be a valid point; the iRobot Create is "just" an automatic vacuum cleaner without a vacuum cleaner, so it's definitely not designed for expansion. Navigation on a line: They have some "cliff sensors" (IR sensors), which might be able to distinguish between light & dark floor. I'm not familiar with the rules of robotchallenge though.. If we can get our hands on a couple of those thingies, I'm certain that we'll quite soon extablish the critical know-how in the lab. ~/= Marius -- We are Elektropeople for a better living.

Details: http://www.robotchallenge.at/reglement/ (I've only watched last year and will probably this year, haven't done any robot projects yet)

I'm now looking into Lego Mindstorm NXT (next generation). Lots of sensors, can be programmed in a graphical environment (under Windows and Mac only) and there are even compiler projects on sourceforge, Lego makes design specs available (up to the point that they document HW interfaces to build your own sensors!). It has bluetooth and usb connectivity, protocols are open. So I think I'll go for Lego :-) Startpage: http://mindstorms.lego.com/ Open Source Firmware development kits: http://mindstorms.lego.com/Overview/nxtreme.aspx Looks like the low-level stuff is under an open source license -- which is *not* currently listed on opensource.org, and I've not had time to read it carefully yet. A C-Like programming language: http://bricxcc.sourceforge.net/nbc/ Communication from Linux (Perl): http://sourceforge.net/projects/linxt/ Ralf -- Ralf Schlatterbeck email: ralf@zoo.priv.at FAX: +43/2243/26465/23

The irobot.com site is lousy (finding things is difficult), but the irobot create documentation is pretty good: - http://www.irobot.com/sp.cfm?pageid=294 - http://createforums.irobot.com/ - http://createforums.irobot.com/irobotcreate/board/message?board.id=Createtes... - http://createforums.irobot.com/irobotcreate/board/message?board.id=Create_Su... - http://roboticsprimer.sourceforge.net/workbook/Main_Page The irobot has somewhat limited capabilities, but combined with a gumstix it could be turned into a very capable piece of hardware. cu andreas
