YES!! FINALLY!!

at 05 am, we finnally debugged our i2c program, turned out it only let 1/3 power through our motor bridge.

OH CRAP

FFFFFFFUUUUUUUU- motor problems again, and, fuck.

testing TESTING...

at this moment we are testing our program and values for our sensors.

SUCCESS!! (once more, as allways,)

we havent made any progress in 30 minutes,.. at least we arent retreating..

still programming

trying to point out some values for our sensors from various graphs and data measurements..
they say, that if its not steaking, its dying, so well just pretend were doing better...

SUCCESS!!

we got our IR sensor array working! problem was a mistake on the board, causing that whenever we turned off our light, we turned off our sensors as well, not that smart, but now it works, and even when it didnt work, we did get eccelent data, meaning our sensors must be pretty norris

2 good news!

we bought food.. mmmh.. and our robot almost works, atleast physically.. we havent started programming yet

waittime is looong.

thats right, 1/2 of the team vent out for parts.. and there's nothing that i can do back here.

SUCCESS!!

we has it!
- we just made a successfull solder!

FANS! bitches! WE HAS THEM!

yes, thats riight, we saw a fan! or, at least a guy whu had a longcat wallpaper..
remember; longcat is loooong

Here We are..

We are at the competition now, we have about 23 hours untill the comp. starts, and yes, that is 23 hours straight, if we are doing good today, we might get a couple of hours of sleep, but again that is pretty unlikely. so, here we are at it again, soldering new circuits, /(and eventually fingers)/ together. We just realised we forgot some connectors for our arduino shield, BLAST! oh well, we got some from another team, kind thoughts to them.

well thats.. interesting..

yesterday, we felt like testing our creation at a smaller competition mostly for kids, however, the layout of the course is the same as the main comp. at DTU.
Whilst the other teams sat programming, we discovered that we werent even able to drive straight, our robot drofe for 5 seconds, and then died. 20 mins before start, we found out that our H bridge couldnt open enough to drive the motors. *FACEPALM*
Anyway, we decided to just take the first port, by connecting our motors directly to our batteries, and that worked pretty well, actually we became the fastest robot, but that didnt alter the fact that we were 18 points from the winner.

Tired

Done for today! Finaly

Science it works bitches!

Finally it works! I laughed so hard when I found out what was wrong - forgot to solder the motor-wires on properly xD such stupidity... But hay it works, and it's only 1:40 am!
Ok now its 1:50, but got some pics.

My not so clean workingspace

More mess

 The finished thing again











Next up: Sensor-cables! :D   And I better get them done tonight...

Ground connection is futile!

Bugs, bugs and more bugs!
First I forgot to add the negative supply for the ics, now that is fixed, but it's still not working...
Going to go it all trough with a probe on, while a program is running. I do believe it's a problem with the AND-gates (74LS08N), when breadboard testing it I had some problems with them going low.
Any ways that is going to be tomorrow. We are getting behind schedule, plans were to start programming tomorrow, but I don't think that is going to happen :(

Robocup - Longcat Is Long - Part I

F1rSt w00t!!11!one11
 - No seriously. It's about this robot contest held by DTU (Danmarks Tekniske Universitet/Technical University of Denmark): RoboCup.
Me and a friend will be participating and thought we would let the world know about our fair.
  The robot will be based on a LEGO chassis, with an Arduino as brain, Pololu light sensors and a home-made motor shield.
  Today we got the last of our components, so now we only need to solder it all together.
  Some pic's of the procces so far:
The light sensor array. Sometimes it's nice to have a crappy infra-red filter on your cam.











H-bridge for one of the motors, hooked up on a breadboard.
