Hi,

My name is Mia. I am the daughter of Markus and the reason why my father could not take care on his robot and rocket stuff the whole week. I was born on 7th of June 2011 at 11:15AM in Shanghai, my birth weight is 2970g and I am 50cm tall. At the night of my birth day I saw the half moon from the window of my room in the hospital. Maybe we see each other one day. Zàijiàn! Mia

Started to program basic movements and teach the robot to overcome taller obstacles than itself by using its robot arm. I'll have a break as my daughter will be born the next days. I'll come back with the TEAM SELENE'S LUNAR BABIES CLUB. M. Bindhammer, Team Selene

Just started to use Algodoo, a physics-based 2D sandbox, as a simple rover simulator. It is easy to learn and is really fun to play with it.

RoverX is powered by two Li-Po batteries (one for the drive motors, one for the arm). During discharge of Li-Po batteries on load, the load has to be removed as soon as the voltage drops below 3.0 V per cell to avoid the batteries getting damaged. The battery voltage is devided by according calculated voltage dividers and then fed into analogue inputs of a PIC 12F683. For now just a buzzer sounds if the critical voltage is reached, later the system will go into the sleep mode and the batteries will be recharged by solar cells.

- Rick Maschek has performed a pH and sieve analysis of the second sample of KNO3 from WenCheng Chemicals that Flint Hapirat had ordered and had sent to Rick. This sample was milled more finely by the company to attempt to meet our requirements. Both the pH (6.5) and the particle distribution were found to be well within the acceptance range.
