Here is something that I have learned over the years that has helped my team (not necessarily anyone else’s just because of our team dynamic)
We usually chose 2 major features, I will use our last years bot as an example.
Last year our 2 major features were
- A drivetrain that could cross any terrain obstical
- a shooter that actuated such that if you reverse the shooting wheels and lowered the shooter it acted as an intake, and could shoot in high and low goals
Now there were several things this did not allow us to do in the beginning
cheval de frise (or however you spell it)
However what we do from there is modify what we had to be able to do some of those.
- we added aluminum flatstock to the bottom of our shooter such that it could go below the portcullis, and when the shooter would actuate into our robot to get into its shooting position it would lift the portcullis
- we also modified the bottom of the shooter to have 2, 1 inch blocks at the bottom to push down the cheval so we could cross
- we also relised that if we come from the back of the drawbridge with our shooter in the intake position, then have it such that only the shooter was touching the bridge, if we actuated the shooter then put it down quickly we could cross the drawbridge
- finally we also relised that if we just spin in the sally port we could do that as well
This leaves just one last thing we could not do, climbing. we were working on a climber after our second district event but did not have the time to complete it. Over the years I have relised this is kind of the limit to our team, small incremental changes can make a lot of a difference if implemented properly. nearly all of what I described above was done in between matches at our first district event last year so its really about knowing what your team is capable of.
blue alliance has us using this bot if any of my explanations were confusing. we ended up winning 2 districts and being and #3 alliance captains (and sub-division finalists) on our field at worlds, so the bot did well. I often find teams have trouble making these incremental changes due to having an incredibly complex bot, but in my opinion (unless your 254, 33, 67, 1114 etc.) it is often better to go back to the basics. my team for example is terrified of using pneumatic, so we don’t, and honestly that’s fine, as long as you can make up for it elsewhere.
here are a few matches if you are curious, or don’t understand the descriptions I provided earlier.
