Bimanual mobile manipulator · 2024
ALOHA 2
Two ViperX 300 arms on a sliding rail, four cameras, and a whole research programme behind it. The canonical platform for bimanual imitation learning — the thing papers mean when they say 'we evaluated on ALOHA'.

Why it matters
If you are doing bimanual manipulation research, this is the baseline every reviewer expects you to beat.
Where it falls short
Rail-mounted, not mobile. Cost puts it out of reach for individuals — build it only in a lab context.
Read this if you plan to copy itThe parts below are the same classes of component at this platform scale — they are not the exact vendor parts. Use them to understand the architecture and to price a home-built equivalent.
