Elevator vs. Telescope vs. Scissor
What do you prefer, an elevator, telescoping arm, or a scissor lift?

Re: Elevator vs. Telescope vs. Scissor
What if it's none of them? Some teams (Spam for example) use arms with joints.

Re: Elevator vs. Telescope vs. Scissor
Dang, thats what I forgot. When adding the choices 3 seemed to little, thanks. OR A JOINTED ARM...

Re: Elevator vs. Telescope vs. Scissor
We have a telescoping arm and while up in the air it sorta goes where it wants to. After attending St. Louis, the Jointed arm seemed to be a nice manipulator but other teams did really well with all of the other types of arm.

Re: Elevator vs. Telescope vs. Scissor
1731 has a jointed arm.

Re: Elevator vs. Telescope vs. Scissor
We've got a 10 foot elevator that starts in the 4 foot category. It locks up, and has worked very very well for us.

Jointed arm with a roller based manipulator, with a forklift style arm coming second.

Re: Elevator vs. Telescope vs. Scissor
I recognized early-on that telescoping arms and elevator style lifters would have an advantage this year since the rack is vertical and requires no "reaching." I think these are the best designs.
However, we decided not to use a lifter since they require more parts then an arm and are harder to build. We have a lot of experience with arms, and we knew how to build one. |

Re: Elevator vs. Telescope vs. Scissor
Last year I savaged parts from TeleScorpio and my mentor showed me how it worked. Since then, I have frowned upon telescoping arms, and for this game I do not feel it is efficient enough to use compared to the elevator, which many teams and robots have used including Chanizilla who has completed its tasks beautifully. As for scissor I am unsure of what you mean.

Re: Elevator vs. Telescope vs. Scissor
Scissors are very material instensive for their lifting ability. For a light game piece requiring quick actuation, a scissor is not the ideal way to go.
A telescoping lift is precise, stiff typically, and good for a heavier, more deliberate, reach type game. A good choice, but an elevator is probably the best choice here. In terms of material/fabrication costs, complexity, and speed, this is the winner. Quick, vertical actuation is easy, and cable is light. However, these elevators are typically quite flimsy at full extension. Not a huge deal with a 1lb tube, but still an issue that complicates scoring. |
