Re: Methods Of Transferring Robot Onto Field?
 

Some teams add attachment points along the robot frame for clip on handles or simply manufacture handles that are a permanent part of the robot frame.

This year we lift it by some convenient spots on our cut and folded sheet metal frame. They are there by coincidence but work well.

Re: Methods Of Transferring Robot Onto Field?
 

Most people just hold it by the frame. That's what we've always done.

If you want a really comfortable handle, you can loop a big zip tie through a thick piece of surgical tubing and secure it to your drive train. If you make the handle big enough it works like a charm. If you have the room for it, its a great way to carry the robot.

Since we had to have belay points anyway, we put the required two eye-bolts at the center of our side-rails and added four extras on the robot corners. When carrying the robot, the students clip on handles made from rope, carabiners, and a short small-diameter PVC section for a handgrip.

This year's frame was a bit short on good handholds, so I think it's been a good choice.

My team has been looking into some anti-gravity methods with no luck. So right now we just carry the robot by the 8020 base.

Unrelated---I vow to never build a robot 70" with no drive train and has to fit under a 30 inch bar and shoots Frisbees

I think this is what we are going to do. Thanks for the replies everyone!

Re: Methods Of Transferring Robot Onto Field?
 

Make sure you get carabiners, eye bolts, and rope that are rated for the weight. The cheap carabiners won't hold up under robot weight.

Re: Methods Of Transferring Robot Onto Field?
 

We have the eye bolts, PVC pipe and rope. Where did you guys get your carabiners?

Re: Methods Of Transferring Robot Onto Field?
 

I don't know where we got ours, since I missed that particular shopping run, but I can provide suggestions.

Grainger definitely has some that should suit. Hardware stores or sporting goods stores that cater to climbers may be good sources also. Just check the max load capacity and be sure to allow a safety factor. The unmarked ones you tend to see in the sporting goods aisle at Target/Walmart are typically rated for about 5 lbs, so they're likely to fail spectacularly when you hang a 150 lb (including battery and bumpers) robot from 4-6 of them.

Re: Methods Of Transferring Robot Onto Field?
 

I made them today and I am sure they are going to hold our 115lb robot. Thanks for the help!

wear gloves too :rolleyes: it's what we do, since quarter inch metal is not the best thing on the hands, but we also grab at the upper part of our frame

Re: Methods Of Transferring Robot Onto Field?
 

353 is the team your talking about with the meat hooks we picked 4 of them up heated them and bent them to what suits our robot( to reach inside and not be in the way of our bumpers) and we used 3/4 inch inside diameter eye bolts that were taller then the height of our bumpers
The reason we don't hold by our frame is we have a lexan skirt underneath to push frisbees out of our way

Re: Methods Of Transferring Robot Onto Field?
 

My team has some rope on 4 steel i hooks on the 4 corners of our robot which is terrible uncomfortable and I am only able to use 2 fingers to do it. It's terrible. Team 3883 The Data bits have similar system, but it is much better. they have a bigger loop on each one with 3/4 inch pvc about 6 inches long. It looks way more comfortable and has seemed to work well for them and we're taking note of it and using it next year.
