Why not use flat paddles instead? For better friction hold and less crushing. Also single arm/paddle support like an open hand for light boxes? Closest I could find: https://m.youtube.com/watch?v=-DQ9c1cFmNg https://m.youtube.com/watch?v=-DQ9c1cFmNg In the second video of the article the first box picked is crushed by the chopsticks.

“In the second video of the article the first box picked is crushed by the chopsticks.” Addressed a bit farther into the article, which I was thankful for because I had the same initial reaction: “ You may have noticed that the boxes in the videos are pretty beat up. That’s because the robot has been practicing with those boxes for months, but Dextrous is mindful of the fact that care is necessary, says Drumwright. ‘One of the things that we were worried about from the very beginning was, how do we do this in a gentle way? But our newest version of the robot has the sensitivity to be very gentle with the boxes.’”

Better example of paddles: https://youtu.be/XPfWvqlEJ48?t=0m48s https://youtu.be/XPfWvqlEJ48?t=0m48s https://www.universal-robots.com/plus/products/onrobot/2fgp20/ https://www.universal-robots.com/plus/products/onrobot/2fgp2... The same paddle head can connect to multiple different arms and has suckers for sheets too. I'm still looking for a good existing example of horizontal paddles with rotating wrist that competes with the chopstick idea. Most examples are restricted to known geometry, but I still think the chopsticks would be beaten by a pair of paddles every time (presuming similar control software). Here's another palletizing arm and grippers combo: https://youtu.be/goivYfJ9DE8 https://youtu.be/goivYfJ9DE8 I mean - imagine tying those chopsticks to your forearms and trying to manipulate boxes - it would be hard enough for a human. Much easier if tied two rubberised rackets to forearms?!
