Hello everyone,
We are a first year high school team, and want to attach a claw to a 6-bar lift for this year’s competition. We wanted to know how to go about designing a claw that can pick up multiple stars.
If anyone can give us an in-depth description of materials needed it would be greatly appreciated. Also, if you could describe the gearing process of a claw, as we are new to vex, we would be greatly helped. Thanks!
The most effective way to do this is to try yourself. Vex is all about learning and engineering. However, I would recommend 2 motors at a 1:3 ratio. But try more.
I completely agree with @Mr_L_on_Yoshi (except about the gear ratio), but here is a videos to give you some inspiration on what a good claw might look like.
Here’s a youtube video with a closer view of the claw (I think it is the same robot as the one in that video).
(starting at 22 seconds)
Is there a way to increase the speed of the claw shown in the video while keeping the same amount of power (still be able to lift up to 4 stars at once and 1 cube at once)? @Michael Nutt
