It is built by Khiew Tzong Yong of ITE in Singapore. He then designed and built a number of other mice for his students to use. In the pictures, these are Robi, Faster Than Droid and Shadow Trexl. Since he designed and made the motor mounts for all these, they will all be similar if not identical. Thus, they are not commercially available I am afraid. I could seriously do with getting hold of a couple myself. It would save a whole lot of work. Perhaps we could persuade him to go into production. Excel 8A is most nearly inspired by Tetra.

I need to read ADc value for every 10micro sec. Is there any time or .. with which i can schedule it. Ok. thanks for help.

]]> Comment on ARM STM32 JTAG by Scot Kornak http://www.micromouseonline.com/2009/12/29/arm-stm32-jtag/#comment-3594 Scot Kornak Fri, 17 Feb 2012 04:22:19 +0000 http://www.micromouseonline.com/wp/?p=245#comment-3594 I have found with the Olimex ARM-USB-OCD JTAG that different boards require different JTAG Clock Divisor settings to avoid the Rowley Crossworks "Cannot set debug register" error message. On one board I could use a JTAG Clock Divisor of 32. On different board type I had to change it to 100 to get it working. These were both with STM32F103 MCUs with 8 MHz crystals. Therefore, I recommend trying some higher values if a particular board isn't working. To change the JTAG settings in Crossworks 2.1, open the "Targets" window from the Target menu, then right click on "Olimex ARM-USB-OCD" and select properties.

Just the result order is heavily random. Using 'total maze time' adds cca 1s to every next run, forcing you to risk the first and enjoy the rest of 7min. In a maze with 2 similar length paths even 'search time' is pointless. Clearly optimal strategy here was to find first path to center, get pronto back to start and do a fastest run. There are some cool videos at http://www.youtube.com/user/suhu9379/videos, we just have to wait for a result report with times. APEC organizers did excellent one last year. Really wonderfull devices.

Turning corners is not, however, its greatest strength.
