Updates: for lack of better words.

Post Concert more, back to bot building and school packing. Yeah sure I have a month until college actually begins, but for me the terms are slightly different so I'll have to get ready by the end of July. Still, there are priorities to be had like finishing Pookie for Wazio.

Last report showed the basic frame plates cut and assembled with the motors and batteries placed. Well since then, I moved those around and I even wired up THE ENTIRE ROBOT!

That is how it looks right now (picture literally taken 2 seconds ago). Fully packed in, drive motors working, and with bottle cap wheels attached. It feels pretty robust and seeing it spin up, I feel like this is a quality competitor if driven correctly.

The electronics are extremely compact. I had to go thought many painstaking efforts to get everything configured the way I wanted them. I had to remove all the pins from the receiver and solder directly to the board. The PWM leads themselves were cut to about an inch long to reduce the amount of wiring running around. I even practiced board stacking where I soldered one board on top of another so save space.

You can see the "power poles" right here between the two boards.

All these modifications allowed the robot to stay really compact. (I need to take a sizing picture some day) All that is left to do is dremel the blade mounting screws off, and to make a new top cover.

Even Pacman got a makeover in time for Atlanta's Dragon Con Robot Battles event. I mounted the motor on top this time to simplify the belting system and added a self-righting hoop to keep the robot on one orientation. Don't worry, running inverted was never a good strategy so it was not like I lost anything. These new makeovers prompted a new color make over so I happily used a different color plastic and some silver to create the illustrations.

One last thin I might do is upgrade the battery for higher voltage and more capacity. After all, I do have 8oz unused.
