Most of my failed projects come from me overstepping my bounds. This time around, I'm looking to purchase (not craft) the components I'm looking for.
I've been looking online to buy two "grippers" (claws?) that will be able to physically suspend a standard 3x3x3 Rubik's cube. The ability to rotate the cube will no doubt rely more on the servos I choose, which I'll do later. For now, the challenge is to find a gripper that can open approximately 3.5" or wider, support the weight of a standard cube and rotate on its base's axis.
This is the only contender thus far: https://www.sparkfun.com/products/13174
Still, the above looks like it will be difficult to rotate on its base's axis, and simply doesn't feel like the right fit.
The most impressive I've seen thus far can be seen here (although they look custom made): https://www.youtube.com/watch?v=SbMhfLkvzss
Can anyone recommend any other options?
