Great video, this helped my team a lot when we we were unsure and unfamiliar with linear slides

you helped me visualize a project of mine a lot better thank you

You should make a more comprehensive video on stringing the slides going into how to properly spool the slides to get reliable motion, as well as maintaining tension on the string

thanks bro

hi, on 1:52. referring to the individual stage. is it gonna act or behave the same if you employ a block and tackle system of pulling it? your input would be much appreciated. thank you.

We are not sure what you mean, but a block and tackle will probably work the same way as the pulleys that we show.

@@Brainstormers8644 i meant with regard to the individual stage configuration, will employing a block and tackle system work the same way, that is, is it going to raise each mast one at a time. thank you for responding. appreciate it

we faced your team and we lost horribly, our robot just stopped moving on the left (your left) platform at the lexington thing

how do you make a slide so goes up with a sting and down with a string so you could pull the robot with the slide

For the first style of stringing, you would connect another string to the top of the slide. One winch would pull on the original "pull" string as a second winch releases the second "release" string, and vice versa. You can see this at 0:45 in our RES-Q Robot Reveal video kzread.info/dash/bejne/fId9zdmxl6acZcY.html where the pull string is adjacent to the drawer slides and the release string is in the center, connected to the tray. The 2 winches would have the same circumference and spin at the same rate. For the second style of stringing, you would need a release pulley which spins twice as fast or is twice the circumference.

The easiest solution is to have both pulleys share the same axis of rotation. One string is wrapped clockwise and the other is wrapped counterclockwise.

is there a way to calculate how much weight you can lift? because i want to lift a tv useing this metode but other materials

That would depend on the stall torque of the motor you are using to pull in the cord. Which I also wanted to ask about. Anyone know what kind of motor is used for this? As in stall torque and type?

For RES-Q, we used 2 AndyMark Neverest 60 motors powering a ~3-inch-diameter pulley. With that, we were able to pull our 50-pound robot up to hang on the RES-Q high bar, but we were probably close to the stall-torque limit on those motors. You should be able to trade off speed for power by using smaller pulleys.

Do you know how to make horizontal telescopic arm?

We give more details of how our Relic Recovery horizontal arm works in kzread.info/dash/bejne/iIirraSDea3WqdY.html

I don't understand why you can't use the stringing method from the first lift to the second lift; it would save weight too. Also, in the 2nd method, can it be assumed that the final rack moves twice as fast as the one before it?

What was the wire you used?

In the video and RES-Q, we used Shine Line string from Quality Nylon Rope. More recently, we also used Vectran-core string from West Marine.

Where do we buy the sliders?

For Velocity Vortex, we used 15mm extrusion from REV Robotics, along with their 15mm linear motion kit. If you need something more heavy-duty, then you can try larger extrusion & connectors from 80/20. For RES-Q, we just used generic drawer slides from Home Depot which was connected to Tetrix C channels.

Hi, my name is Jacob Homan. I am a Senior Mechanical student at Wright State University's Lake Campus in Celina, Ohio. For our Senior Capstone project, students are required to build an autonomous vehicle. I am intrigued with your lift and linear movement and would like to research further in regards to possibly pursuing this concept into our design. Can I please have your contact information so that I reach out and ask questions pertaining your lifting mechanism? Thanks in advance,
