One of my concerns in this project was power supply. The power supply will be two 12V 38Ah sealed lead-acid batteries connected in series. That makes 24V which is good for the motors, but will toast any other electronics. So what we need is more suitable 12V power. One solution would be another 12V battery, but I think it's quite a hassle to charge two different batteries etc.
So what I am going to do in this project, is using this ShenZhen Huangjintai Electric 15A Negative Booster. It converts 24V DC into a 12V DC. Simple, Reliable, Chinese.
From 12V it it easy to regulate 5-6V for the arduino, servos etc. with regular hobby UBECs. 12V is also more suitable for fans, lights and eeePC.
