How stretch_RE1_arm achieves scaling

Hello Doctor:
Excuse me , can I ask the question : how the stretch_RE1_arm achieves scaling ? what is its driving method ? by electric push rod, by hydraulic, or by line drive ?
Looking forward to receiving your reply !

Hi @Flock_wind,

Welcome to the forum! We support openness through our open source software and some open hardware, such as accessories in our tool share repository. However, our core hardware is proprietary with patents pending, including the internals of Stretch’s arm.

Best wishes,
Charlie
