The original intent was to demonstrate dead-reckoning accuracy by doing a programmed (autonomous) 360 left circle and a 360 right circle (or vice versa). But in truth, it's always harder than it sounds, and we always like to see new robots, so we mostly dispensed with the rules.
Creative interpretation/cheating is king, though. Some of my favorites that spring to mind:
1) Ttailspin's bot was struggling, so he duct-taped (?) it to the top of a Parallax S2 robot that carried it around a picture-perfect, wheel-encoder-accuracy figure 8.
2) Martin_H did the "Oval Challenge" (different thread, same spirit). He made an oval cardboard wall, which his wall-following robot faithfully orbited. Pure genius.
3) Martin_H also made his robot arm draw a Figure 8. Probably in Forth...
Duane Degn has a lot of neat bots, hexapods & mecanum wheels using IK and a great deal of razzle-dazzle.
All these guys expose me for the true hillbilly hack that I am!
Hope to get something together in the next week, naturally I have reached my data limit this month. Can a small video be posted here, or does it have to go through utube? What format is best?
Thanks,
_Mike
That is too cool, but if we let the RC guys in, where will that lead?, I mean, will these guys want in too?... https://www.youtube.com/watch?v=AeGZEk0ftPg
It's all good, After all, a figure 8 is a figure 8.
And "Robotics", of course. But let's face it, a lot of what people call "robots" are just radio controlled, like bomb disposal robots, pyramid exploring camera robots, and of course drones. The lines are permanently blurred, and that toothpaste is not going back in the tube.
Ok, using the strictest interpretation of the rules of this challenge,
Wall-E and EVE do indeed complete a figure 8... Good to know... gonna store that away with all the other important things i know.
Mars Spirit and Opportunity got me interested in doing something like this, but it was the successful landing of the Mars Curiosity Rover MSL that got me started in earnest. The original design was to have two Propeller's, but it started out with a BS2 controlling a P.S.C.U..
Most all of the sensors and other boards are already included in the robots firmware, but are in the process of being socketed to proto boards.
Aa drill press and hand tools we're all I used, to get to the fun I'm having now with it.
Below is a list of my pin assignment's, some of which can be changed like stereo, P.S.C.U.rx, GPSrx.

@MikeDYur, any video service is acceptable. Some people use YouTube, others Vimeo, use whatever works.

Somebody will have to sit down, watch the movie again, and report back...

Is it front or rear wheel drive?
RoboMagellan is calling, Mike!
Yes I did, no budget for nothing fancy, but I had aluminum!

Nice! I look forward to hearing more about this project.
