01 / Under the shell
The specifications.
Hardware, build and software on one sheet. Every fact links to where we found it.
GELLO Mechanical is the central repository for mechanical parts used by GELLO, a teleoperation framework for robot manipulators. It contains robot-specific parts for multiple robot types; the STL files can be printed directly, and the README links to assembly instructions.
