Brain change 1. step

So, unhappy with the programming of my robot, and not wanting to start programming something totally unknown, i proceeded to desolder the original cpu, from my robots pcb.. luckily i had the spare one i got earlier, because i made a MESS of the first one.
But with a bit of solderwick and a lot of patience, the second one was a succes.. Now to install something different.
In went a Arduino MEGA 2560, with a dfrobot breakout board.
Now i placed that on a wooden board, that i fixed in the robot with hotmelt glue.
NICE.
Now if i could only connect it to something

The support department

So I called the support department to get some support. I wanted it to go the other way around. No luck in doing that, no instructions or otherwise. But. He was interested in some development, and I thought I could use a new hobby. So I got an updated robot, an extra motherboard, a list of different arduino parts, a stack og lithium ion batteries and off we go

Brain change 2. step

ok, so now i needed to connect the Arduino mega, with the old cpu socket. I got the inspiration from  a site i find searching for "grau goes color" He pulled apart a Tianchen TC-G158 robot. This robot is a cousin of the Supoman, using almost the same motherboard layout, so i started using his psuedo drawings, and most importantly i used this drawing as a basis seeing what my motherboard contained. MY board was a bit different.. For one the cpu, while still being a 32pin STC12C5410AD, wasnt in a lqfp-32 , mine was in sop-32 package. Mine also has an IR sensor pointed downwards, this being connected to another multiplexer, thats always pointed at the sensor.. i guess its a buffer or something So i had to trace the functions, and heres my resulting IO list. The sheet also shows how i linked it to the mega. The mega then was powered, from the old stc's programming connector, connection pin 1 & 4 of the programming port, to the micro usb. Then off to ardumover   t...

The beginning

So..I  bought a robot lawnmower, a supoman, called rotenbach In germany. And being me, I didn't think it did a good enough job. It didn't cut the entire lawn, in one go. It went the wrong way around the garden. I couldn't put the charging station Where wanted. And it gets stuck too often. Not nearly good enough so of course, ill hack it.
