Get the gear that you put on the motor shaft. Put it on the shaft. Now, put the motor in. Tighten it down.

I believe you need to order extra retaining rings, CIM gears, and keys.

Re: Our robot is done!

For the flag holder : there's four inches from the back of the scissor lift to the back of the limitations that the flag will fit on. we had to allocate the room especially.

As for hurdling when we get to the top : the manipulator goes up with the lift, so with a slope and lowering that over the first bar, the ball should roll right over, as long as we position it right.

And most people are correct, we don't plan to want to knock the ball off explicitly, but we do think with the cradle on there we will be able to actuate the scissor lift when we are -underneath- the rails to be able to hit it, it's not something we're designing for yet, and if we are able to do it it's a nice accessory ;P

Re: Our robot is done!

Fantastic design! This allows for a good defensive build and the ability to hurdle! Great! One question- how long does it take to extend the scissorlift to hurdling position?

Re: Our robot is done!

Good question, haha, I'll get back to you. From preliminary tests with actuators it seems like it will go up rather fast, and we actually may have to run down the pressure from max on these things. We're now using, after more testing today, 2 2 inch bore 12 inch stroke actuators, and we plan to tweak with the psi to get them to run at a reasonable speed. I don't see speed being an issue though, and we're shooting for, I don't want to sound unrealistic as I suppose I don't really know exactly, but maybe around ~6 seconds? Five? I'll let you know as the weeks progress.

Just a suggestion/helpful hint.....A better way to slow down the cylinder actuation would be to use adjustable flow controls on the cylinders.

Get ready to eat your hat then. ;P

Seriously though, unless we find a major flaw, this is the -design- we are going to go with. Not the exact mechanisms or anything... but as I said those are the ideas we are running with.
