Claws for DR4Bs

My team is planning on adding a big claw to our DR4B. However, we are unsure about how we should build it. Does anyone have any designs they could share that is both light and good quality?

not light but it is good quality

i have 2 motors geared 2 to 7 and i am just using grippy matting on the middle width
c-channel
mine is a 6 bar but it is the same concept

So if would it be a good idea to add treads on a clawing order to pick up cubes more easily?

Why 2 motors? Isn’t that excessive?

What do you mean it looks very light :wink:

not at all for a clamp that picks up 4 cubes also i didn’t have anything else for the motor
