Ours is coming in tomorrow. Pretty nice. 
Anyone playing with it already?
Our teamās edu is supposed to get here on Thursday
We got our 2004 EDURobot Controller today!
Hooked it up to an RC controller and all works well, now we need to tackle programming. Shouldnāt be too bad
God my school district hasent even fronted up the money for it (stupid rich ppl 
) how do yaāll like the new controllers?
got it. Havnāt had time to mess w/yet.
Received ours and tried it out. At first, I didnāt think that you could run it without the hobby RC equipment, but then read that as soon as it is powered up, the code begins executing. This would simulate an autonomous mode.
Hooked up a potentiometer to the analog in and set āpwm01 = IO1;ā in the āuser_routines.cā and was off and running (C is case sensitive so be careful). Cool little box!! Those guys at Innovation First make the coolest stuff, and their documentation is wonderful too. What would we do without those guys???
how exactly would i go about getting this into autonomous?..cuz i dont have an hobby R/C at the momentā¦and i need to learn the new code
We just got ours,and I wired it right into the āMiniCrabā, my Crab/Skid eduBot. Weāre still pursuing a controller, but the two pivoting servos will lock into center position when turned on! We also need to upgrade my PCās OS so I can start Proggin. Has anyone tried the loader on 98? I know itās not supported, but still, has anyone seen if it will work? Iām going to try it in a minute, I just restored a nice registry to get my pc running again
Unlike like yearās robot controller that waited for either a valid radio signal or tether connection to begin processing your program, the new Edubot controller with the C language automatically begins running your code when powered on.
See page 3 of the ā2004 EDU Robot Controller Reference Guideā on the Innovation First web site for more details.

You will need to add some of your own code to make the EDU robot controller behave how you would like it to.
yeaā¦i added my custom code to itā¦and it just sits there and does nothingā¦does it have to do w/ me still using Windows 98?..or does that not have any effect?
basically what i did wasā¦i connected 2 multi-speed motors on pwm1 and pwm2 OUTā¦and in the code im telling it to go full forward (pwm01=254;ā¦etc) and nothin happens. Any advice?
thanks

After updating your code, you need to āMakeā your new code (F10 is the shortcut). MPLAB will show you the progress and create a new *.hex file. Use the IFI loader to connect to the robot and download your new *.hex file. If you saw this happen, then your OS is working and something else is wrong (maybe below).

WHERE you put the above statement is important. Try at the very end of the āuser_routines.cā, or at least after the last "pwm1 = " statement in the default code. Otherwise, your statement for pwm1 will be overwritten.
Good luck.
The reason it wonāt do anything different is because Win98 canāt build HEXās w/ C18. The Hex loader does work, however, and this is good news for those who have a low-end dashboard laptop for competition. (me walks over to old 486dx4, me installs NT Workstation)
we still have ours from last year, im going to be showing off my hoverbot tomarro at Robot Rodeo
Our EDU finally came today. I thought FIRST were supposed to ship the EDUās out a while ago but at least they came. We were actually supposed to receive the EDU yesterday but it arrived today. Wonder what went on?

FIRST used ground shipping.
I FINALLY got to the point of being able to compile and upload to the new eduRC. Whew.
And, the results are really cool. While we still donāt have our R/C controller yet, I programmed it to do a few things. First off, Iām using my crab-drive edubot that I built before we got the new controller. Iāve gotten it to basically strafe around in different shapes, circles, triangles, squares, etc.
Iām having a bit of a problem w. the servos thoughā¦
The Range of the pwmXX variables is still 0-255, right? For some reason, The HiTec Servos from last yearās kit wont go all the way around to 0 when 0 is sent, and wont go all the way around to the other end at 255. They do center at 127, though. I tried a few different things, but Iām still having some issues getting them to go from 0 deg (0) to 90 (127) to 180 (255). And Yes, I know that the servos actually have over 180 degrees of rotation, so these numbers arenāt 100% correct, but the problem is that they wonāt move enough. Iām not sure why. In all my previous work with servos, I havenāt had this problemā¦
Anywho, Iām trying to find a small portion of free web space I can link to to post up some video of the bot in action. Weāre still in the process of getting our ānewā domain set up.
Are you sure about the servo range? I had a HiTech servo that only had a range of about 100 degrees.
Yeah, Iām pretty sure, but maybe youāre right.
The servos Iām using are from last yearās kit.
Hey, Itās good enough for me to get it to do a few shapes, so Iām fine for now.
I really like the fact that it can be programmed to run without any special equipment. I already have tons of auto modes programmed within just one day! And, you can switch betwen them easily.

niceā¦so do iā¦ but how do you easily switch between them? i just have separate .hex files.
