Re: 2017 Drive Train
Ultimate Ascent is definitely a good game to reference. Shooting, cross-field cycling, hoovering scoring items, and two giant structures clogging everything up. The biggest difference is you can't expand the field by driving under the obstacles. 4 robot pile-ups next to one of the airships are going to be common. Being able to push around the side of that pile is going to be important.

Re: 2017 Drive Train
Based on the current stock Andymark has for Toughbox Micros, I think that a lot of teams are going for mecanum.

Re: 2017 Drive Train
This is very good advice. Any robot with a mecanum or omin train will likely be very easy to push around and be highly ineffective at both shooting and gearing (my proposed term for scoring gears).

Re: 2017 Drive Train
We used h-drive in 2015 and got it working great. Mechanum is something we have never done because a) we haven't needed it and b) its more complicated than a tank or h-drive. For this year's game tank drive is probably best. For lining things up, just practice with the tank drive and build some mechanisms in for maneuvering game pieces within the bot.

Re: 2017 Drive Train
I would actually disagree with this. If you have a good gear ratio on a mecanum you can get a decent amount of force. Our team went mecanum in 2014 and we're actually able to push the more basic tank drives around.

Re: 2017 Drive Train
Basic question but couldnt find it anywhere else:
How fast does the andymark KOP chassis go? |

In fact, Ultimate ascent was easier than this game when it came to driving, because you could put yourself in safe zones when you shot. This year? Prepared to be pushed while putting the gear on or shooting into the goal. Build a tank drive. |

Re: 2017 Drive Train
On a slightly different note, what motor / gearing / wheel size setup are you all using? Ideal feet per second I would imagine is relatively high. Shifting or no shifting? We are leaning towards 6 cim ~10-12 fps no shifting but I don't have great experience to tell if we got it in the right range or not for this game.

Personally I'm not a big shifting guy, I think it takes a very skilled driver to use it effectively. |

Re: 2017 Drive Train
Here on 1640 we plan to use our swerve drive again (big suprise). This year we are also going to introduce our CVT swerve to the field.

Re: 2017 Drive Train
I personally think mechanum or Omni with tread-wheel hybrid. That's just an idea though. Problem is the amperage for mechanum.
