XMOS Challenge : ONR robot beginnings

Description of the ONR (maybe a real name TBA)

This robot is to navigate outdoors from point to point, possibly going through a series of predetermined points. Point location can be marked by traffic cones, GPS coordinates, or other orienteering markers as detailed in various contests like Robomagellan or the DPRG outdoor contests.  Requirements include finding and recognizing the point, as well as negotiating any obstacles between points, and maintaining a remote stop.

Stuff to do

Stuff to do..

Think I've finally figured out Jaimies Spider Tank walking mechanism, pretty cool. You have to picture the legs with your head tilted sideways at a 45 degree angle, while scratching your head and rubbing your stomach. I wonder if this is how Jaimie figured out the walking mechanism to start with. Think I'd like to build a small model with some hobby plastic bits to verify thoughts. May get a few model airplane hinges to build with, or just make some small hinge joints some way.

Arduino servo twitching

Servo twitching. I know, simple stuff, but it's interesting to play with on new hardware. Another Arduino example "sketch" (they got a number of these) called Sweep simply moves a servo through a set range, back and forth. Just looking at the sketch (listed at bottom) this timeshows a servo controlsignla connected to pin 9. They recommend using the boards 5 volts to power the servo, which is coming from the USB connection. If I'd had a bigger servo, or was under load, it might be appraoching the 500 mA USB limit (or is it more now?).

Blinking an LED in about 5 to 10 minutes

Earlier today got a FedEx delivery of a MakerShed order placed last week. Toys!

 One particular toy was a new Arduino Duemilanove. Had to see what made the Arduino popular.
