Next Hack - Robot B9

i found about 1200 on ebay search rubber bellows right now not at the point to buy any yet,hopping to finish my omnibot frame and post photos and parts of all parts used,i see most dont post a complete parts lists for each section of the robot makes it super easy to build any robot design anyone makes if a part list is made

BRET on ABS if you use instead of the aluminium design,www.mcmaster.com has very cheap prices on ABS sheets many sizes and types i get my parts in 2 or 3 days very fast shipping delrin not a good choice unless you sandwitch it between other plastics and very slippery and paint hard to stick,same with nylon,mostly great for gears and fixtures

THanks for the great insight everyone! It sounds like ABS is the way to go. I will order some today. My design is fairly simple and if it works I may make a mold and make cast resin pieces.

What is the ID of the bellows you need? I can look around here and see what I have.

going to do the same on my omnibot design and B9 design ,make resin molds to sell

whats super great about using resin molds compare to fiberglass,first no sanding is needed,very flat surface,sometime stronger,a lot cheaper,plus not very messy and easy to shape in a mold i know JOSH loves using fiberglass a lot ,BUT ITS NOT GREAT FOR ROBOTICS,unless you are will small holes using only BONDO

@brett hey man , why don't you get the arms working then make bellows. I bet I can figure out how to mold some like the way I did sams new rubber tires. Turns out silicon worked much better than natural rubber for molding the parts. Didn't you already have a section of rubber that matched the id you needed? If you do and you need more I could cast a mold and make more.

Can't wait to see these crazy arms moving around , really khudos to you! I think you did the best b9 arms ever. Even comparing them to the life size replicas I believe these will move more like a robot and less like s guy in a suite.

BRET here are some hints and ideas on making molds

silicone is easy to use,and molds not hard to make too what i use a lot in making molds is moulding clay,sometimes you need a release compound to remove your cast from the mold,also parchment paper works great or vaseline

THanks guys, but I found motorcycle fork boots that will work fine for me - although I had been considering molding a pair of bellows before I found these.

and Thanks Josh! I am pretty pleased with those arms.

Have you made his claws yet? I just won a bid for a 24 inch B9 off of ebay and will be modding him as soon as my humanoid robot is finished. Also my B9 is missing the front leg panel. How much would you charge for a copy of the leg panel? Looks like a fun project. I have always love this robot.

Congrats on the B9! I'm glad to see some other people finally starting to hack this great toy - I thought I was the only one haha. I haven't made the claws yet, just have them designed. But hopefully will get back to robot work this weekend. Sorry, I have a lot of stuff already attached to the front leg panel (door) and wouldn't even know how to make a leg panel. Mold I guess. I know that robotmaker also has this bot and he seems like he can manufacture stuff really well. You might check with him on making you a mold or a copy or something. He has posted on this thread so you should be able to find him easily.

I can't wait to see your progress with your B9.
