[FTC]: Rev Robotics Linear Extender Kit Preguntas

[pilum40]

We received a couple of Rev Robotics' linear extender kits and a load of 15mm extrusion. Can someone point me (a non technical teacher) to an assembly or instructional video I can show my students to get this done right? I've assembled the pieces but am having issues with the nylon pieces popping out of the ends of the extrusion. Any help would be welcome. Thanks

also how would I power this set up to extend and retract? I've got some Vex linear motion kits but am not sure if they're legal. I could attach the rack onto the extrusion I'm thinking and run it through the system. Not sure if the Vex motor will be strong enoiugh. Again...any help would be appreciated. Thanks

Hey Steve,
I'm sorry your having some difficulty getting our linear motion system going. Send me an email with your contact info and we can get you all sorted out.

Thanks,

Greg

We machined a few parts that allow us to have v-grooved bearings on the outside of our slides. The wires are set up in such a way that all of the slides move at once, when the bottom wire is winched into the robot. I haven't seen any videos/manuals from RevRobotics yet, but I imagine that Greg and the team are busy getting ready for the FRC season.

The way that we designed our lift, required us to combine two 17in sections together for all of the middle slides, (We have 4 sliding sections). On the tops of these combined slides, we also tapped a plate into place, that holds the middle, double slider in, as we couldn't figure out how to keep them in place, so we just let them free slide in place.

We're not privy to machine shop so we'll have to figure out a Fred Flintstone type of solution LOL. Could you please send a photo to me so I can translate to my freshmen? Thanks...

I will do so in a little bit. Currently at work. While we have access to a machine shop, the parts I'm talking about were made with a chop saw, thrown together jig, and a drill press.

pilum40, please look at your email, just sent it to you, from my office.

I am having a similar problem. I looked at the instructional guide on the REV Robotics website, but I still had trouble determining exactly how to make one side of the slider lock onto the extrusion, while the other slides free. When I attempted to assemble it, it seems like it is locked on both sides.
Thanks for any help.

I will work on getting a video tutorial up this weekend. It has been on my todo list for far too long at this point. Until then, if you need anything you can always email me. greg [at] revrobotics [dot] com

Just an update. We shot the video for this this, and it just needs a bit of editing. I am hoping to get it up this week. Sorry for the delay.
