Cassie

Cassie was a legs-only bipedal robot derived from Oregon State University's ATRIAS research and sold by Agility Robotics to universities from 2017. Its ostrich-like legs became a common platform for reinforcement learning locomotion research. It set a 100 m record for bipedal robots in 2022.

How the score is built

Capability is what the machine physically does. Value compares it with others at a similar price, not with the whole market. Buyability asks whether you can really order one. Ecosystem is the software and community around it. Proof is what it has done in the field, which is where most humanoids score badly and should.

Digit

Commercial

The 2023 Digit added a head, improved hands and a taller frame, and is the version Agility Robotics sells as a service for moving totes in warehouses. It was the first humanoid with a paid, multi-year commercial deployment (GXO, 2024) and is built at Agility's RoboFab factory. Schaeffler invested in Agility in 2024 and planned to deploy Digit in its plants.

Digit (v1 to v3)

Retired

Digit added a torso, arms and perception to the Cassie legs and was first shown in February 2019. Ford bought the first two units in 2020 for last-mile delivery research, and v2 and v3 added better perception and hands-free manipulation of totes. These versions were superseded by the 2023 Digit.
