Popsicle Stick Hexapod R.I.P.
Seeing OddBot's Chopsticks robot on YouTube was a revelation to me. I all of a sudden realized one didn't need to spend a lot of money making a walking robot.
Not having many chopsticks on hand I turned to another inexpensive building materiial craft sticks. I like calling them Popsicle sticks since that's what I called them as a child. Of course Popsicle sticks are technically used to hold Popsicle brand frozen treats, but I'm hoping I wont get in too much trouble using the term loosely here.
To provide a second pivot point and reduce the stress on the servos, I used 2x2 (studs) Lego turn tables.
Everything is held together with Polymorph, Gorilla Tape and a few nuts and bolts.
The Popsicle sticks are much too long for these servos. My earlier walking attempts didn't work at all. It was only after raising the bot's stance did it have a chance to carry its own weight. It was still too weak to carry the microcontroller board or the batteries.
I wrote the walking code myself. While the gait looks like it's doing what it's supposed to do, I'm not sure I had all my IK equations worked out correctly.
I obviously didn't know what I was doing but that was kind of the point. I just wanted to try it. It was a fun failure.
I've since reused the servos in my other hexapod.
Thanks OddBot for the inspiration.
