For anyone interested, I'm auctioning off a SUMO11 Based robot. The SUMO11 is 100% HandyBoard compatible. The Platform is LEGO based with 2 Sharp GP2D12 IR...
I would say implementing "fuzzy logic" is language independent. Certainly a pure C implementation should be translatable function by function to IC. There may...

Hi , I have built a few HBs in my day and I dont think there is a problem with the chip. But if you had connected a serial cable you may want to check it for...
Hi: I am using the Handyboard in conjunction with Fred Martin's Book, Robtic Explorations. In Figure 2.8 in the book, there is a photo showing the completed...

<snip> In its simplest terms "fuzzy logic" is an algebra of "likely membership". The typical example is what is the answer to "is it warm outside?". Some...
Hi, i have a problem with the Distance Measuring Sensors. when i use the sentence "printf(" Sensor %d is %d\n",17,analog(17));", returns always a value between...

Xiaoming, I had this problem as well, if you are using the gp2d12 ranging IR sensor. The fix is that the handyboard uses a 47kohm pull up resistor and...

Hi: I am having a problem using the servomotor on the expansion board. The servomotor is controlled by two sensors. If only one sensor works, the servomotor...
... My batteries reach 11.5v when fully charged. If your wall wart only gives 12v, you'll only have 0.5v across your led which isn't enough to light it. Most ...

Hello, I could use an extra HandyBoard for a project I am working on. If you happen to have an extra HandyBoard that you no longer need I would be interested...

Mr. Hunter I realized that the NiCds were not being charged with much current even when I used a separate battery charger. I did a little research and...
... That would explain it. I use NiMHs in mine so I don't have that problem. Can't leave NiMHs on trickle charge though, which is why I comandeered one of the ...
Hello, I don't recall seeing this topic come up so I thought I would ask... Has anyone tried using a pair of RF radio Modems to communicate with the HandyBoard...
I got some 433Mhz serial transmitters and recievers from http://oatleyelectronics.com. I can't see the ones you've linked because the site seems to be stuck in...
