arduino bootloader

hi every one 

kinda noob to this programing and stuff :) 

i have a small problem maybe some one could help me. Ive just bought 2 Deek robot mini boards ardunio clones but i dont have anything else to upload sketches into the borad other than arduino uno so i found tutoriel on google how to set it up.

Motor control with PID and PWM

Working on adding encoders to my project and could use some resources/help on understanding how to code pulse width modulation (PWM) with Proportional Integral Derivative (PID) to control brushed DC motors. Any help would be wonderful.

5800mAh 2S 25C Lipo for Dagu Rover 5? Power Distribution?

I am setting up a Dagu Rover 5 plus 4 channel motor controller plus  Spider
robot controller plus Rasperry Pi.

The power supply from 6 NiMH batteries will not be enough for my Dagu Rover 5.
So I was looking for LiPos.
Found this one:
 ZIPPY Compact 5800mAh 2S 25C Lipo Pack
Capacity: 5800mAh
Voltage: 2S1P / 2 Cell / 7.4V
Discharge: 25C Constant / 35C Burst

Best platform for self-balancing and running biped robot?

I had some questions regarding how much computing power would be required to make a small scale 2 legged humanoid robot, that could go running (or 4 legged like those Boston Dynamics robots)...what type of programming (Picaxe basic, Arduino, C?) and board would be best to use?  There would be so many servos, a lot of real-time balancing and vision data to process.

Let's make a biped together

Hey there, I am about to make a self-balancing biped. I have experience in software development, 3d design and animation. Now experimenting with Arduino and accelerometers. I am open for joint development. Let’s share experience and do this together.

Connecting i2c on Raspberry and Arduino: wrong information on websites!

I wanted to connect my Raspberry and the Spider controller board with Arduino
via i2c.
On websites like
http://neophob.com/2013/04/i2c-communication-between-a-rpi-and-a-arduino/
http://blog.retep.org/2014/02/15/connecting-an-arduino-to-a-raspberry-pi-using-i2c/
I read that I can simply connect both as long as Raspberry is the master.

But there is some important issue, if Raspberry and Arduino stay connected:
if you do nothing in the void loop() (like the blink example) and/or if you do
