@Thorondor Since we can't choose more than one option, we do not use chainsaw, but we came up with it ourselves and used it at our first competition. We then tested the side-rollers and found that it worked better for us.
I am interested in hearing why you didn't like the chainsaw intakes.
@FirePhoenix We had a regular 2 roller intake, but when banditoffernando said that you guys could cap goals at will, I couldn't resist. Plus it fit well with the new design of our robot. WASABI having one too also encouraged me to join the bandwagon. Hope you won't get mad at us for using it. :D
I'm not mad, in fact I am somewhat happy that our design ideas are inspiring other teams, especially world champs like WASABI.:)
@Jij I myself don't use the "chainsaw intakes", as we don't seem to have any problems with our single sprocket intakes. If they are tweaked right, they shouldn't cause problems. I would definitely be using "chainsaw intakes", except I worry the "chainsaw" could break or snap off. And btw, there is a team in New Zealand that were using them a long time ago, and this team used them at the Robot World Cup ;)
I don't see why they are any more likely to snap off than anything else. I am aware that other teams were using them first, but my team did design them independently and posted a reveal on the forums. Re-watching the world cup videos I now see that robot.
