FTC 2017-2018 Relic Grabber Design

This is latest design for our robot for FTC 2017-2018 season game "Relic Recovery". Twitter user @curiobot requested design to be posted, so here it is.
Design is based around using @Actobotics servo blocks, while pricey, they are very-very useful. Shape of grabber designed by utilizing negative shape mold that would allow to use little force to hold "Relic" figurine very securely. I will post video later with prototype demo.
2017-11-24: Adding second, less aggressive claw design, because first one if pushed hard enough towards Relic, would lock in place and HT 485HB servo did not have enough torque to release.
Successfully tested - It works beutifully
