Get The Maximum Out Of The Sandstorm Period


#21

I suggest that whenever your robot is operating fully autonomously, all members of your drive team should raise their hands, as if they’re on a roller coaster.


#22

If my team ends up going fully autonomous during sandstorm this year, I think we’ll try this instead


#23

Quick question related to the Sandstorm period, particularly related level 2 drop. My team was looking at using some sort of strafing mechanism, but someone mentioned that the high rate of impact due to dropping off level 2 might have poor effect on any strafing mechanism we try and employ, specifically poor ability to strafe, bearings breaking, and so on. Would you guys expect a similar result? It seems as if this were true, the only safe wheel base that wouldn’t have that problem would be pneumatic. Thoughts?


#24

Most omni-wheels and mecanum wheels aren’t going to like being dropped much. Some of the higher-durability traction wheels (aluminum hubs in particular) are going to take that kind of impact better. If you have a strafing setup that’s retracted at the time of impact so that you land on something stronger, you might hold up better. I’ll note that if you’re strafing off level 2 parallel to the driver station wall you’re going to basically fall into a ball-pit since that’s where the depot is. That’s likely to be a bit on the tippy side.


#25

To clarify this point, the roboRIO has a built-in accelerometer, but not a built-in gyro. It might have a gyro if you have a navX mounted on top. (There’s also this newer IMU that mounts via the SPI port.)


#26

Driver control (with dual cameras possibly) would be the most efficient way to go and would work the best in that situation. We actually were thinking “semi-autonomous”, like, we would get it in place and then have the robot use the vision system to position it to place cargo or a hatch.
