season six of battlebots is here and we're back with an upgraded version of the bloodsport you saw in NUMBER_TOKEN now with NUMBER_TOKEN percent more blood and of course a whole new set of blades to talk about last time we went through all the reasons that our tri-bar broke against gruff last year and now we've got a brand new version to avenge the old one i'm nick weapons engineer for team bloodsport and if at first you don't succeed try try again to recap for those who are new last year at battlebots we showed up with a tri-tooth blade to try and solve some of the problems that we had in NUMBER_TOKEN namely the fact that our bot was horribly unstable and even flung itself out of the arena one time explaining this effect can and will be its own separate video eventually but it turns out that a long narrow bar will want to tumble in all kinds of strange ways after a hit while a triangle spinner like sunawayachi will stay level because physics bloodsport isn't son of wayachi though and our weapon is about NUMBER_TOKEN pounds lighter than theirs so obviously the construction of our tribar wound up being pretty different we had good luck with our solid three-quarter inch sNUMBER_TOKEN tool steel bar in NUMBER_TOKEN so we gave it another go in NUMBER_TOKEN. a tri bar is totally different though and between adding more weapon weight splitting that weight and strength between three arms rather than two and the overall brittleness of sNUMBER_TOKEN the tri-bar died a spectacular death at the hands of gruff so what did we change for the new version well the most important change is that instead of using sNUMBER_TOKEN tool steel we switch to arNUMBER_TOKEN which is a tougher steel alloy that they use to make dump trucks and shooting targets NUMBER_TOKEN is not as good at cutting as tool steel is and it's actually a bit weaker but it has a much higher impact toughness meaning that it's way less brittle and won't be prone to shattering like the old blades we do expect to see more wear and tear on the teeth and maybe even a bit of bending in the long term but that's just how it goes at battlebots nothing lasts forever but as long as we can finish the fight the part did its job of course we can also try to minimize the bending by changing the design to make try again stronger we put a bunch of holes in the middle now actually what this does is take the material from the middle of the base of each arm where there's almost no stress during a hit and move it out to widen the base of the arm and strengthen everything in that area the arms are also a bit shorter with the new tri-bar being only NUMBER_TOKEN inches in diameter instead of NUMBER_TOKEN these two changes make the bending stresses a lot lower and makes try again a lot stronger at the point where the old tri-bar broke now that we have a design and a material choice the weapon actually has to get made this is where one of our new sponsors comes in for this year tal steel tel steel is a steel service center serving much of southern california with a huge variety of different steel and aluminum options tell also has a wide array of different tools and machines to handle the fabrication needs of their customers ranging all the way from band saws to water jet and plasma cutters they had exactly what we needed and made up the new tri-bar for us to exacting specifications along with another new bar
