You wonder how a gear box worked, or how a level sensor worked, check this website http://mechanicalebook.com/videos.htm it has several interesting videos...
hi all i am trying to create a robot club which will teach robots courses , help beginner robotics hobbies , projects and so on ..... but i want a formal...

Hi, This message is related to "100mHz counter". I want to know if building a laser ranging module to measure distance is plausible. Heres how it works: ...
We have some extra resistors we will probably never use. On behalf of www.theyshallwalk.org I would like to offer them to any Seattle Robotics Society members...
LOL, this all looks ok in theory except for the oopic section. the oopic internal runs, (at best), 1/4 of your crystal speed. it may not be fast enough for...
Nice implementation of fueling robot. Little slow though. http://www.tankpitstop.com/index.php?pid=6 [Non-text portions of this message have been removed]...
Also, my dad and I discussed this a little, and we also plan to use a um-FPU ver 3.1 as the math processor. So, the oopic will only handle the display part....
Yep. It is possible to do laser range finding this way but... I have looked into this before and had trouble locating components that were fast enough. I'm...
The sonar ranger might give you some insight. You Might study an IR ranger such as the GP2D12 sensor with a Range of 10 to 80cm. Study how it works. Simply...
Well, I've located a 900mHz 8-bit counter (I can chain this to form 32 bits). My dad and I still have some concerns on if the oopic can handle the speed....
I think that the entire measurement process will have to be done in hardware, you don't even need a microprocessor at all. The µC is only good to make the...
That's a real robot in my book. Supposedly going into operation later this year in Holland. What's the point of robots like this though? Here in Oregon we...

That's pretty cool Fred.maybe we can team up or something (a thought). Well I was discussing this issue in DPRG (www.dprg.org <http://www.dprg.org/> ) and...
I’m going to use a 650nm 5mW laser diode, and a OPT101 as the detector. I already experimented with my laser pen (650nm, 5mW, diode) in a very dark room to...
I may have missed something along the way but counting at 100 MHz gives a time tick every 10 Nanoseconds. This would give a range resolution of 10 feet per...
... Be very careful with CPU speeds. A 1GHz CPU is nothing like 1 GHz hardware logic. Remember that.. - The "1 GHz" is the core clock of the CPU - Each...
if you need true 250-500Mhz counter for your range finder, then it is hard to beat a CPLD or FPGA. as stated below, a PC or even an pico-itx is horrible at...
Hi I did refer to the OPT101 datasheet.... Apparently the OPT101 has a bandwidth of 14 KHz, so it's nowhere near fast enough for nS timing . It has a rise...
It might not be as slow as you think. By the time you get out of the car & walk around the car, the robot might already be fueling. Same on the end game...
I haven't looked (I'll leave that to you) but I wonder if the input capture on a microchip, atmega, or either an ARM or Motorola DSP would be able to run at...
Again, it doesn’t matter how many times it triggers in a second, I’m just worried about the counter and it’s resolution. ___________________ Ray Xu ...
