-I'm starting to play around with small agri-vehicles, starting with commercially available stuff that resembles the OSE Microtrac. It seemed like a good idea to familiarize myself with the CAN Bus architecture to make things easy when that showed up. So, I got a few arduino shields and a Microchip piece of junk that doesn't even pretend to be a serial device. pff.

 But, I got an arduino sketch to send data over that CAN bus.

-I've been working on a robot with a Raspberry Pi brain, Arduino controller, and a Pololu Zumo Chassis. Using these three ready-to-go components, I've really got a jumpstart on a lot of the interesting software. I've built a low-cost spherical reflector using a capnut shielded and supported by clear acrylic. With that, a cheap USB webcam, and the Raspberry Pi, it just takes a little software to extract the bearing (angular heading) to any pixel in the image.

 The answer is MOAR POWAH. I will be building an OSMC to gently squeeze the everliving amps out of our batteries and gracefully ramp speed on two motors.

-I like this idea of [[JenettsProjects#IR_Harp|Jenett]]'s. Maybe we can do it with lasers [http://www.stephenhobley.com/blog/laser-harp-2009/the-laser-harp-pages/] once we get the IR version working.

		+	We will make a 12-legged Jansen mechanism in a form factor more similar to a Chebyshev mechanism, which hopefully, we will be able to ride. Driving and steering mechanisms left aside, and gait also being considered much much later, we begin by building one leg.
		+
		+	Based on computer models{here}, the construction methodology takes advantage of the design's slicability. That is, linkages can be layered or stacked, with no possibility of collision between two linkages that are stacked on different layers. Cool. Easy.
