In honor of the Figure 8 challenge's 10th anniversary Monday, here's an all-mechanical robot kit I just built today. Fun to build and an interesting design, the path is "programmed" to steer using pegs on a central wheel which alternately lifts the left & right wheels, which rotate together as a solid barbell.
Just in time for the 10th anniversary of Erco's Figure 8 Challenge.
Propeller >> PPM >> RC Transmitter >> 'Bot.
Not bad for open loop, low traction wheels and a CR servo with a drifting pot. Each circle is 10.3 seconds, I adjusted the speed while keeping the loop time constant. The drifting pot on one servo made it difficult. I plan to redo this, but for now I'm impressed so here it is.
That's BEAUTIMOUS, Jon! Way to come down to the wire and get the Gold medal! Bravo! I hope to knock another quickie together tomorrow to celebrate ten years. And guess what the traditional gift is for a ten year anniversary? (SO PERFECT)
10th Anniversary: Tin or Aluminum
Look out, world—you've tackled ten whole years of marriage. The decade-long anniversary gift is traditionally tin or aluminum, which symbolize the strength and resilience of your marriagerobotic challenge.
Limited time today but I DID slam this aluminum (traditional 10th anniversary gift) chassis together and coax it through a figure 8. Happy Anniversary and thanks to @Martin_H for starting and everyone who has contributed to make this such an amazing and long-lived thread!

And now for something completely different!

erco-approved! Includes accessories: gripper, forklift, pen holder, soccer ball & catapult!

Preliminary experiments indicate that a square figure 8 works better than a diamond pattern. I need a government grant to fund my research!
Amazing job Whit!!

Nice, that looks familiar. Was it Feetech?
Not Feetech, but similar to the MakeBlock robots you've likely seen. A BoeBot knockoff, except that it uses DC motors instead of CR servos.
