    Wait a sec! I thought that was your tongue-in-cheek video of the Falcon Heavy launch. Do I need to go back and look at that again?

  • Oops, sorry Phipi, I initially posted the wrong video!

    Sometimes when viewing several different videos on Youtube, the URL doesn't change. I was looking at the right video, but I cut and pasted the unchanged URL, which was the Falcon launch.

    Took me a few minutes to catch that mistake. A thousand apologies, nothing close to a figure 8. Although the twin booster landings was a perfect figure 11. :)

    Kickin' it Old School today. Guess what Ms. Dollar's Robotic's Class is doing with their BoeBots! PBASIC is still so much fun.

    Here is my example for the class...

    Bravo, 8th Man! Nothing wrong with old school. Boebots still have lots to teach.

    Whit: Is that CBA robot still in your flock? I can't recall if it ever did an 8.

    Yes CBA is still in the flock - Can't remember either!

    Right now I want to duplicate what Carol did with my S3 and LaserPING)))s in Blockly. The challenge is still fresh!

    Carol's Blockly code appears to be doing at least the Proportional portion of PID to measure the distance and adjust the wheel speed proportionally. It would be interesting to watch several consecutive orbits (LEDs and long exposures, Carol?) to see how consistent they are. When I did Spiderbot, I used a Sharp sensor as a simple go/no-go (actually seen or unseen) to decide to walk straight (seen) or spin (unseen). Not proportional at all but it worked well enough. Git 'er done!

  • The robot goes around the the tubes several times in the original video. Is that what you are asking? There are indicator LEDs on top of the robot
    showing what it is looking at at the time. I will make a longer one though and see if I can get a better shot of the Pings laser lighting up the tubes.
    You will notice it always leaves the area between the tubes in the opposite direction it entered, hence a reliable figure eight movement.

    Good first effort. IMO your sensors should be well in front of your wheel axle so that when you rotate, you instantly change the distance. That works well for wall-followers, which is pretty much what you're doing with a cylindrical wall. A larger diameter cylinder will be easier to track, of course.
