Excuse Me, is that YOUR Bot?

Up until now, I've been having people think that the giant timing pulley robot was my entry for the Beetleweight class this BARF. Well, surprise! I'm taking off the covers, the bot is nothing like expected!

Welcome to the new version of Late Night Leftovers (I might change the name to Shark Attack)!

It sports a 9" edger blade, weighing about 9 oz (I think). Total RPMs should come out around 8000-9000 which should really put a punch on the tips!

Other upgrades include more robust drive motors from my old robot "Ron". Essentially, it is Ron. All the parts came from that robot, but it is just packaged differently. Either way, it should prove pretty interesting and I'm curious to see what it can do to others, say a cake pan ;)

But you ask, what happened to the vertical disk version? I'll tell you, it practically broke it self. When the gigantic disk hit something, it made impacts tangent to the axis at a low angle. So basically, it pushed horizontally against the direction of forward motion. The friction coefficient of the tires are fairly high. So if froward forces are high, but reverse forces are also high and on the same plane, where does the force go? Into the drive motors, because it's the weakest part. Yeah, the 50:1 copals decided to burst: rather just the bushings. Either way, once they blow, I can't fix them easily. Redesign.

Here's to a good but short lived bot.

You were interesting and adorable. Farewell.

One more day till BARF. Better keep building.
