Erco's Peg Puzzle Challenge: Arm Yourself!
Figure 8 Challenge? Pishaw.
Oval Challenge? Yawn.
Towers of Hanoi? Gimme a break.
Martin_H, PhiPi, Duane... who will answer the call? The price of entry? $1. That is, you'll find the peg puzzle at the dollar store!
Sorry PhiPi, the solution may not be recursive: http://www.joenord.com/puzzles/peggame/index.html

However, maybe just for you, i will drill one more board and turn 14 more pegs, before Xmas..But, the Robot arm is months away..
I do have some thin stock i put aside for a steamy glue up session.. it's the good stuff from my private reserve,(2000 years old).
I may not have to sell all my woodworking tools just yet, there may indeed be just one more thing to build...

Have you tried your local Cracker Barrel?
Well now you're just braggin'...
We'll have to get one of our 3D printing gurus to make a special version of this triangle game just for robotics. Instead of golf tees, a ~3/4" hollow hemisphere with a grasping peg on top, and a triangular base with 15 molded domes to automatically center the piece on top.
The "gripper" can be made from a plastic sleeve bushing, a flat-head machine screw, and a tiny super-magnet the same size as the screw head. The magnet adheres to the screw head, and that assembly slides into the plastic sleeve. By moving the screw in and out of the sleeve via a servo or solenoid, the magnet approaches or retracts from the bottom sleeve opening. When near the bottom, it will attract and pick up the bearing, without the bearing having to touch the magnet. The bearing is then automatically centered against the bottom of the plastic sleeve. When the screw-and-magnet assembly is retracted, the bearing will drop.

Yes, the guy never sleeps!
But when he does, he dreams up great stuff!
I was contemplating cutting a dowel into 2" long pieces. On the tops I was going to glue smooth plastic disks so I could pick them up with my suction cup gripper. But smooth plastic balls would work better, and counter sunk holes would center them close enough for the grab to be consistent.
Now I just need some smooth plastic balls about an inch in diameter.
erco - come on! What would Matt say?
The problem with this one is that Google gives you all the answers.
Having the robot "look" at the puzzle, design a solution and then carry out the solution ARE multiple problems - each a pretty complex task at that.
I don't think even the most sophisticated robots in existence could just let you put and puzzle in front of them, see it, solve it and return it finished. That would be a amazing accomplishment.
At least the base (the biggest piece and 90% of the puzzle mass) is...
PLYWOOD!
IBM Watson must have delicated his life to medicine. With a precision arm, could be programmed with every game in the book.
Martin, how are you coming on this challenge? I'll get back to it after the Christmas crunch.
What I have left to do is work out the gcode for the motion script. This is tedious, and the least technically challenging part of the project. It's also the part that's hard to stay motivated on because it is huge amounts of trial and error.
The reason I need new IK code is this robot is neither a scara arm, nor revolute arm. So I haven't done this sort of IK before.
