Healing Heart, Drunken Pit Bull: Making Peace

"Someone shouted "OH SHIT, it's coming back!"
The dog then grabbed a can in its jaws and bit down hard, puncturing the can and shaking it like a baby -- which sent streams of malt liquor shooting out of the holes around its fangs and straight down the monster's throat. It spat the mostly-empty can out into the street, covered in drool and malt liquor and wagged its tail, happily burping.

The man picked himself up and yelled "motherfucker, what did I JUST TELL YOU," and grabbed the dog by its neck and belly, clean-and-jerked it and threw the thing like a soccer ball as far as he could. It hit the pavement and skidded, snarling and growling and ran straight for him, knocked him down again and grabbed another can.

This cycle had been iterating for a little while.

Mecanum

So, Segway's selling some new robot platform, which I'm sure will get press far beyond its merit, but who cares about that. The interesting part is the crazy wheels it uses: I hadn't heard of Mecanum wheels before, but they are nifty. This video of an electric wheelchair shows how it works pretty clearly: if all four wheels are turning in the same direction, it does the obvious thing. But if the wheels on one side are turning toward each other, and the wheels on the other side are turning away from each other, it moves sideways! The controller is neat, too: it looks to be a joystick that rotates.
