You may also notice that many of the fast HP stackers (i.e. the Einstein winning alliance) did not need ramps tethered to their robot (or a third robot).
This echos what a mentor from one of the Einstein winners said in the 13th post of the following thread. We added an RC stabilizer after our first Regional. If we had done our strategic analysis properly, we would not have added it. We would have had it on our robot from the beginning and we would have done better at our first Regional.

One of the biggest mistakes I see teams (FRC and FLL) making is that they copy without understanding what they are copying. It is good to study another teams design to add to your repertoire of design techniques and mechanisms. When you copy only one piece of someone's design without understanding the whole, you may miss copying another part of their design that is crucial to the success of the part you are copying.
The reliability that you are after has as much to do with the quality of construction as the design of the robot. Your team may want to look at the construction practices (mechanical and electrical) in the off season and make any necessary improvements in the off-season. Your off-season robot can be the final test for any training you do. Monochron's comments about the lift are spot on. Or lift mechanism was built crooked and when it was first installed, there was so much friction it had to be forced up and down. I highly recommend the "Electronics Tutorial" videos published by Code Orange. We had ZERO electrical problems this year through two Regionals and Champs.

Our electrical team is great our mechanical team is bad. We also had zero electrical issues this year mechanically we have been a mess for years.
Me and a few other students analyzed this game quite a bit. Ill definitely watch those videos though.
Thanks for the help just a quick question.
Best way of setting up chain to work with this system. The middle is off limits due to it being part of the ramp so we would have to have chains at the corners. Do we need it on both sides how would we set up the shaft running through the top. Is back drive a big issue and should we plan on having to set something like a bike brake.
And since we never have done chain any tools we need to buy.
Thanks
