So I have just recently got into Bot Ball, however I have got several beginner questions. For one I was just wondering what is the precise height limit? Another simple question I need to know is what is the advantage of a create? In the 2013 board (this might be for all the boards, like I said before I am a beginner) you get one create able on the board at a time. Please help! I really appreciate you guys for your time!

Hi Ben,

Good questions. In 2013, I believe the height limit was 15 inches, but for official rulings you should check the official rules PDF and the Home Base FAQ.

The Create is quite fast (500 mm/s top speed), has quite consistent movement, has good sensors, doesn't require any building expertise to use, can power Link motors with much more power than a Link can, and can act as an independent 3rd robot if you want to. These are the advantages I can think of off the top of my head; there may be more.

Oh yeah! I forgot, I was wondering if there is a width limit? I know that the create itself is pretty wide, but if you put multiply attachments on the the create (or link) it can get wider and wider. My robot does not get much wider than the create, but if there is a width limit I would love to know about. Thanks again for your time!

The only width limit that is currently in play (or at least for 2013) is that your robot may not exceed the volume of the starting box. After the game starts, however, your robot may expand.

Good question! I haven't ever pondered that until now!

I know Jeremy answered this question, but I'm going to add on. The starting box is 15 inches but I've seen the judges give leeways. Also, the advantage of the create is that it is fast, and as Jeremy said, you could script it to be an independent robot, it could carry a lot more weight than the Link robot, it has more momentum (P = M * V), it is generally more stable, it has it's own sensors such as IR and cliff and bump sensors, it has a stronger engine(motor), and it gives you one extra chassis to use. And, it cuts down on you motor bracket use.

Hope this expands on Jeremy's answer and hope this helps.

For any of the people out there who try to use the KISS IDE simulator, I found that the simulator for KISS IDE 4.0.5 will not take Create functions; it will only run Link motor, servo, and other functions only.

Hope this prevents any further problems!

Okay okay, I know that I have a lot of beginner questions, but I was wondering for the link chassy what is the propose of the little cardboard circle in the wheel? In our group there was a problem were there was not the cardboard circle on the wheel. We sent a good 5 minutes trying to find a circle. I did not see what was it for. If any of you guys could help that would be great!

Thanks

Yah Ben I was wondering about that too because I would see it on some robots but not others.

I may be totally wrong, but, if you use logic, what is the difference between cardboard and that plastic thing? Cardboard has more friction. So, it might be to reduce friction of the wheel. But, I don't see why we need reduced friction so I may be on cracks.

Hmm never really thought about that... I would guess that it may be cheaper to make them that way or it could be like YuSheng's answer.
