well my one deffinitely wont win, it will have acetate and grippy feet so it might be able to push a bit but acetate doesn't help if the robot it's on is gradually falling apart by itself.
after some more work, it's starting to really take shape!
if the mechanisms i've designed and put together work alright i might even considering building another walker for the final member of my fleaweight team as they're good fun and very interesting to build. here it so far:
i now pledge that if zingo is any good i will build an antweight walker as they're so much fun to design and build and i'd like to see what i could do with a 225 gram weight limit.
Even if it's not any good, you can use what you learnt to build something more effective into an antweight. I'm currently working on an ant walker, and you're right, they're a lot of fun to design and build (although my one's taking forever to make )
looks like the next step for me will be to change the HDPE slide hoops that convert the motion from rotational to linear for some smaller ones made out of paper clips as the HDPE ones are too wide. this adjustment should allow the mechanism to walk much more freely and stop itself from jamming at high speeds.
Rory: will your walker be ready by the AWS? if so, i would like to see it compete.
I'm still thinking all-walker annihilator at the end. Lead Piping in the Billiard Room, Skutter, Kwejiboom, Zoink!, Mecha-Spall...could take ages though.
here it is after a bit more work. currently weighs in at 63 grams with everything except switch, reciever and ESC. also below are some pictures of how the mechanism works.

rectangular cam part is rotated by the motor and bolted to a leg at a single point allowing it to push and pull the leg through it's rotational path with the guide hoop keeping the final output motion of the leg linear.
