Welcome to the project site of Team Per Ardua ad Astra. This site is meant for documenting the team's work for the Singapore Amazing Flying Machine Competition (SAFMC) 2011.
Team Per Ardua ad Astra was formed in 2009 by a group of 6 students from NUS High School of Math and Science interested in design and engineering. The team was formed to take part in the Singapore Space Challenge (SSC) 2010. The team emerged champion in the competition.Since the end of SSC 2010, the team has looked forward to its next project together.
Setting up the Serial Servo Controller (SSC)
We are using a 6-channel USB SSC obtained from Pololu. Hence, some of the instructions may be a bit specific, though I'll try to generalise.The SSC is the one that will receive instructions from the main OS and pass on these instructions to the Electronic Speed Controllers (ESCs). It'll be the one that will know which ESC to pass a particular message to me, as instructed by the OS. Hence, when testing the SSC, there are 2 main things to check:Whether it can receive information from the OS.Whether it is able to pass the received information to the respective servos.Pololu has an entire User Guide on their site so it is a good ...

Setting up Gumstix and communicating with your Linux(Ubuntu)
Communicating with Gumstix:1. Download the 4 files from SAFMC->Gumstix.2. Set up a bootable microSD card as described in this tutorial: http://www.gumstix.net/Setup-and-Programming/view/Overo-Setup-and-Programming/Creating-a-bootable-microSD-card/111.html' - instead of /dev/sde1, your card maybe mounted at sdb1/sdc1/sdd1 etc. just try and see which one you get into. Mine was sdc1. It will change from computer to computer so nothing to worry about. Just use the same thing consistently then. - Towards the end, you will need to know the mount point. To find out, go to Disk Utility in Linux and check the card. You can mount it from Disk Utility itself also and ...

Parts list and RTOS choice
So over the last 2 months (more so over the last 2 weeks), our team has finally reached an agreement on all the parts we need to buy. We would like to thank NUS High for sponsoring us for this project. The first major argument we had was over the board. We had to chose between Beagleboard, IGEPv2, Panda Board and Gumstix Overo Fire. Finally, after counting the number of PWM, UART and etc. ports, we realized that we could only use Gumstix Overo Fire or Panda Board. And sadly, Panda Board will not be available till late March (the competition will end by then!). So with no choice left, we ordered Gumstix Overo Fire. These are the other parts ...
