wow, 8.02g is surprisingly light. is the rotational center to the front of the motor shaft or actually to the back? I am looking forward to see if 0.4mm PCB is strong enough for your case. How much did you spend to fabricate a 0.4mm thick PCB no larger than 5x5cm?
This is much lighter than I expected. The rotational center is almost on the motor shaft. 0.4mm PCB is strong enough for crash to wall, but I'm afraid that it will be damaged by putting in and pulling out connectors of the battery and the serial communication cable. This PCB was about 25,000 JPY.
The cost of your PCB is a lot more expensive than I expected!. The price at iteadstudio is only 10+30+20=60USD(without shipping) for a 5x5cm 0.4mm PCB, which is about 6,000 Yen I assume. I guess you got this expensive for reason such as much better quality for faster fabricating speed.
Hi,Kojima san. I am a student at the Lunghwa university of science and technology in Taiwan. Dr.Su is my teacher. Can I know what manufacturer part number of IR sensors that you are using?

Hi. Thank you for your comment on this blog.
And, I enjoyed the Taiwan contest this week owing to the staff members of your university and Dr.Su.
IR emitter is OP265FAD by OPTEK and IR detector is SFH229FA by OSRAM. I hope this can help your development.
Thank you for your reply.
I very enjoy and amazing for your half-size micromouse design.
I will try this IR sensors for my new design.
