Use a C-52 EVB for simple robot experiments. Build
a simple two wheels robot with L293D H-Bridge driver and IR sensors.
Write a C program controls robot tracked with black tape. Fun with Ving-Peaw
Competition 2543, course layout, day-by-day changed rule and scoring
One of my student has made a disgraceful robot that used two stepper
motors and with a simple IR sensor. Yes, above picture is what I'm talking.
Without battery carrying, a little bit torque of the stepper and misalignment
of driving shaft, makes it crawling not walking, but first demo, showed
quite impressive to me. He said he wrote a couple of program lines using
C, his robot can track the black tape. I feel delighted his intention
and endeavor. I thought, " he borrowed me DS5000, expensive one,
a soft uController with internal bootloader, why shouldn't try with
our learning board C-52 Evaluation Board instead". Another one,
told me the same day "I found the L293 Push/Pull Four Channel Driver
at Ban-Moah, it costs 1.5 US$ ". I've been searching this chip
for a year. The MiniBoard, a Motorola 68HC11 Robot Controller board
designed by Fred G. Martin, also uses this driver. The day after, I
then decided to prepare the page describing how to use C-52 EVB as a
robot controller board. I asked my student for competition, build yourselves
robot that can track the black tape. Prize for the winner is 100 US$,
with a bit condition that the winner must pay for a big party at Soi
Jinda's Somtum (Papaya Salad) shop. And one of the competitor is me.
I thought the rule should be conceived roughly by students and technically
by me. The picture on that day will put here soon.
C-52 EVB resources
Beforehand, let look at available resources of C-52 EVB for robot experiments.
