	Prototype Alternatives and Design posted by Matthew Meador on 3rd December 2007 New Checkfs.sh A new checkfs.sh for the init.d has been written and tested that will allow the boot process to proceed even if fsck fails or finds errors. The overall objective of this script is to log errors but not impede startup during autonomous testing later on. Unfortunately the used hard drive the University provided is already having errors and making very disturbing sounds, so a brain transplant to a USB thumb drive is soon to come. Design Choices The alternatives report consists of methods for approaching the different modules design (locomotion, branch detection, etc.) and our proposed solution. We ended up going with a caterpillar design, which includes a top and bottom clamp connected by a vertical segment. Horizontal movement will be achieved by bands on the clamps, and the detection system will be sonar based. This is a precursor to the prototype report, which is the initial specification of the design. Prototype Specification The culmination of the semester: The Prototype Specification the group has compiled is an extension look at the design based on the choices made in the alternatives report. Next Steps Currently the project is gearing up for the next phases of the design process, construction and testing. The aim is to have every component ordered before winter break. Fortunately we already have our i2c from Diolan and our SRF02 sonar devices from Acroname, so hopefully the next post will include successful communication with these devices and a first iteration of tree-mapping.
