Printed Treads and a new BBot

BBRoverTreads

Just got our hands on a new Taz6 3D Printer from Lulzbot! We’re going to break it in attempting to print treads for the BBRover tires out of Ninjaflex

Taz6

10 hours later… We got a great looking tread with a nice snug fit around our stock BBRover tire, but we’re going to push the Taz6 to its limits and go bigger

The new bigger design was a success! Really happy with the results from the Taz6. With a little help from our magic glue (stuff sticks to everything), we’ve got new treads for our BBRover Monster Truck edition, and it’s ready for action. Big motors, big tires, big wheels, big fun

After completely shredding the EPP wheels on the BB Monster Truck going 20mph straight into doing donuts, we’re seeing a lot of value from the Ninjaflex tires.  That stuff is TOUGH. We’re still not getting the traction to climb stairs like we were hoping, but it might just have the speed we need to convert into a launcher for our plane (hint hint wink wink)

Tread comparison

Alright, we just can’t stop playing with new treads until we’ve finally climbed something! We’re working on a new variation of BBRover which we are convinced will get the job done. Here’s a sneak peek

Tank Tread

One side complete! Sized to fit a BBRover setup with the Shorty BrainBox and modified BBRover wheels. There is enough stretch in the Ninjaflex tread that it fits snuggly. The new wheels have teeth which engage the slits on the tread, ten at a time. Initial tests show it stays on fine while spinning. Waiting for the other side to finish printing, more tests to come

Introducing the newest member of the ever growing BoxBotix family, we’re calling this one the BBTank. This little guy should finally have what it takes to tackle some rock obstacles

Went out looking for rocks to climb, came across something even better. A short walk from the office and we found ourselves an awesome little urban obstacle course to put the BBTank to the test

CONCLUSION

Awesome results for both the BBTank and printing treads out of Ninjaflex. We’ve already got grand plans to modify our tread design so it can be printed in sections and pinned together. This allows us to scale our tank tread to fit any size requirement. From there we can make a tread that fits a full sized BBRover, or a shorty version with wheels big enough to drive upside down or right side up. Our urban obstacle course shows the potential for the BBTank to traverse through places like construction sites, war zones, areas suffering from natural disasters, etc. We think the BBTank is here to stay
