I think keep away is the best defense this year rather than typical pushing matches. So a fast light bot that is easy to drive is where I think my rookie team should go. Maybe some curb feelers to get a bit more reach on the balls.

The most competitive robot I ever helped build was both fast and light, and also short when the manipulator was down. I could carry it myself tucked under one arm, as could many if not most of the students, especially if the battery had been removed. The second (or perhaps third) most competitive was the same length, only a bit wider, and while it was taller, the superstructure was very light weight, just enough to support control boards, a game piece, and a sheet of corrugated plastic. I buckled each of those robots into the passenger seat of my Saturn Vue more times than I could count for demos. So, I am all on board with fast, light, and small frame perimeter.
My concern here was that with two tall arms and maybe a blockinator, the high center of gravity would make the robot tend to fall over if placed on a small drive base and driven as vigorously as FRC matches require. Further, reduced length and the extension limits may (or may not; I havenât done the math) keep you from hooking the ânextâ rung.

G106 says you guys cannot extend past 5ft 6in in the hangar zone, It really looks like you guys are extended past that, could be wrong but something to keep in mind.
They know that, they havenât set limits in code to adhere to those rules yet. This was a proof of concept to show how it will work and if and a rough timeline. their next steps will be to limit the extension of the arms and possibly automate the process to maximize efficiency.

sweet, just making sure that you guys knew that! Looks awesome

Not on the team just restating the OP words.

Yes, I know it is too tall. Moved the mount point 5 inches lower and moved the spool out of the 2x2 to gain another 2 inches of lift. That will be enough to reach the next bar without going over height. Hope to have it all together by end of day next Saturday. We are about 10 inches over in that video and we have about 6 inches or so to spare for making the hook.

Really cool and efficient design!! What kind of motors did you use to rotate the climbing mechanisms.
If I understood correctly, theyâre just passive (spring forward, and the weight of the robot forces them the other way).

I love this. A lot. Most aesthetic climber Iâve seen in years.
I am guessing people want to know what spring I used, so here it is.
This gas shock dampens in the extension direction but not in compression. So it allows the arm to smash into the backwards end of motion. I am working on decreasing that impact, as it can cause the hook to be pulled off the bar.

So to update 8825 was able to climb to 15 every match but one out of 15. Yielding a total endgame point average of 14. As of week 3 that makes it the best Rookie climber and tied for 10th best climber overall. Here is a picture of the robot

Congrats! That is a great achievement.
Thank you for posting your design, weâve had similar success with it. We couldnât have done it without your generosity!
Best,
