Wow! Maybe too much weight reduction? ;)
- can you control it?
- is it too flimsy to withstand the knocks during competition
I basically I had the same questions when I first saw the video. Another concern that I foresee is it’s longevy. How well will it last over time?
With an arm that light, I’m interested to see how light your cone intake will be.
This is funny to see how fast you can make the lift go, but I really hope you invest in some stronger materials and I really really hope this doesn't "inspire" any new teams to build a lift like this.
1x1 L-Channels and 25 Hole bar are poor load bearing members normally (except for in tension, maybe), but having Swiss-Cheesed them the lift might as well be built out of Popsicle sticks. A particularly strong wind is going to convert this robot into aluminum spaghetti long before it makes it into the actual competition.
I don't want to be rude and abrasive, but with a lot of new teams on the forums, it needs to be pointed out that doing things like this in the name of "weight savings" on crucial systems is a terrible idea.
