Re: pic: Grant Drives Tumbleweed
This was definitely one of my favorite moments this year. Thank you John and Parker for the opportunity, and 148 for building such a sweet robot.
I was kinda nervous going into it, I kept bugging John "so how do you drive it.. how does it work.." His response was "it will take me a minute to describe how it works, but it will probably take you the whole match to really figure out how it drives." Which was completely true. I have a huuge new respect for Parker, driving this little thing is extreemely difficult. It took me probably half the match to get it around the track consistently, and probably the rest of it to figure out how to make slight adjustments to avoid traffic. The defensive and evasive maneuvers that he pulls off are just beyond my comprehension.
Let me give a few insights.
- If you hit a wall, you're out for like 5 seconds. it messes up the gyro or something and the robot gets confused and seems to always choose "drive hard into the wall"
- If you stop for even a second, good luck reorienting yourself and figuring out which way is forward. When they say there is no front, they really mean it.
- Making turns in a precise direction is pretty much a guessing game because of the way that they have it turn (at least, it felt like it to me). Doing little juke maneuvers and stuff is wayyy more difficult than with a tank steer (or even a conventional swerve drive)
Sweet robot though. Sorry again that your matches with our bot didn't go so well (tipped over in hybrid, then the arms broke [not his fault] so he never got the chance to hurdle)
