Is the DryLin N Linear Guide Systems provided from the KOP a good choice as a guide to pick up multiple box. An arm is considered to be attach to it that will hold 3 or more boxes. Will the guide break and how will torque affect it? Overall thoughts???
You can find the engineering specifications here:
The carriage part is WW-10-40-10 and the max torque is listed as 125 lb-ft (170N). If each tote is 8 lb at a distance of 1.5 ft from the rail you’ll exert a torque of 36 ft*lb on the carriage with three totes.
Looks like it should be OK. You can double the carriage and space them apart to give extra strength.
The drylin guides are great and won’t break for this application. Torque will prevent a single slider from moving quite easily. If you have 2 sliders with a distance between them it will diminish the effect that a load will apply to it. It will also decrease your range of motion of the Drylin guide which may be a problem. If memory serves then the Drylin linear guides are 30" long. If you are trying to lift something >25" I would look at another option like www.Competitionrobotparts.com. If you have any questions feel free to PM me.
I will also shamelessly plug the REV Robotics extrusion system, It has built in v-grooves designed for smooth rolling of heavy loads. Check them out at www.REVrobotics.com

How would we brace the REV system? I was trying to CAD it up yesterday and realized that the bases got in the way of the slider.
+2 I was part of the team indiana Ri3D group. Even without reinforcing it quite as well as we should have the REV extrusion with V-bearings worked flawlessly. Huge amounts of adjustability to get the spacing and squareness of the frame just right.
We used the IGUS DryLin W track on the 2014 robot for our Spring guide system.
We are planning on using it again for the lift system this year as well. We would use 15-5M HTD belt to position the slider mechanism.
