Want to see how our frame was built? We designed all of our aluminum unibody frame to be waterjet cut by Big Blue Saw! The frame is all 1/4", 3/8", and 1/2" 6061 aluminum plate. By designing the parts with interlocking puzzle tabs, there is a strong mechanical joint even before welding!

This method allows for super fast construction, accurate jigging for welding, and a strong mechanical joint by having the zig-zag weld area, and lots of filets for welding.

If you design parts, you can upload them to bigbluesaw.com and get instant quotes, including the material costs, and see how your design affects the pricing! No need for sending out for quotes and waiting, they are super easy to work with.

After all of or parts were waterjet cut, we were able to do minimum fit up work, jig everything together, and get Applied Welding in Mountain View to weld everything up for us! Welding thick aluminum requires a very experienced shop to ensure proper penetration and minimal warping. Eddie Irlanda is our man for welding everything!

Tune in to BattleBots tonight on ABC Television Network at 9pm! We face off against Team JACD - Battlebots and the "kids from Massachusetts Institute of Technology (MIT)". Who will win?! BattleBots WPI Alumni Worcester Polytechnic Institute (WPI) Magmotor VEXpro VEX Robotics

Curious why your tabs are setback such a small amount of your material thickness? Doesn't it limit how big your weld can be along that seam?

I'm not sure exactly what you mean... The tabs all have a 1/8"… Więcej gap for weld filet, but there is still 1/4" or 3/8" of overlap, so I don't consider that a small amount. The amount has worked really well in the PST for manufacturability and robustness, for example in Brutality's frame.

Awesome work ! Really interested in the gear ratio or how tracks were attached to output shafts or if it's just wheels inside track.

now I wanna build a robot with that kind of construction

The edges look a lot smoother than any waterjet cut I've seen. Is this just a good waterjet machine or did you finish those edges later so the tabs would fit nicely?

Not every company or waterjet is the same... Big Blue Saw as… Więcej the option for the "low taper cut" which has a tilting head to compensate for kerf removal. Additionally, when you specify for the higher quality, you can achieve a smooth ready to go surface (for example if you wanted to make gear teeth). It saves a lot of time and money, and the parts come out really well.

I have to say when I first saw this bot from afar it looked pretty bland but the more detail of the design I get to see the more impressive it is

Can you guys show more of the tread construction? Those are by far the most robust treads I have ever seen!
