The specifications.
Hardware, build and software on one sheet. Every fact links to where we found it.
SROI is a parallel-gripper end effector for strawberry harvesting, also configured as a handheld device for collecting first-person visual and action data. Its three configurations operate the gripper with a joint motor, a slide button, or thumb-and-index-finger motion.

Can you sell it?
Check firstCheck before commercial use
No license was found for the design files, so no reuse rights are granted. Ask the maker before building anything to sell.
