Digit, Agility Robotics
Digit Humanoid Robot
Digit is a bipedal humanoid robot developed by the US company Agility Robotics. The company previously became known for Cassie, a running walking robot capable of moving autonomously over varied terrain. Building on experience gained with Cassie, Agility Robotics went a step further by creating a full-size humanoid capable of performing repetitive manipulation tasks in environments designed for people.
Digit was created to move freely through spaces where a conventional wheeled robot would have difficulty operating, such as stairs, narrow passages, or uneven terrain. The robot features mobility resembling a human posture and additional arms that allow it to carry light loads, open doors, or operate simple devices. Agility Robotics emphasizes in its materials that Digit is intended as a practical solution supporting logistics, warehousing, and the service sector. It is therefore not merely a research platform, but a commercial project designed for work in real-world conditions.
History and Development
History of the CyberOne Humanoid Robot
The Digit robot is the result of several years of work by the Agility Robotics team that began with the Cassie project. Below is a brief introduction to the key stages in Digit's development, illustrating the manufacturer's commitment and evolving vision.
Roots in the Cassie Project
- Agility Robotics originated as a spin-off from Oregon State University. Its first well-known project, Cassie, focused on developing a bipedal robot capable of stable and dynamic walking.
- Cassie demonstrated that bipedal machines can become relatively energy efficient and resistant to loss of balance. Demonstrations included walking over uneven terrain and short runs.
Decision to Create a Humanoid
- Further development and accumulated experience led Agility Robotics to expand the project with manipulation capabilities. Cassie's lack of arms limited the range of tasks it could perform, inspiring the team to design a new, more versatile robot.
- Engineers concluded that adding upper limbs would enable not only load handling, but also more natural interaction with the environment, including opening doors or operating devices designed for people.
Presentation of Digit and Initial Tests
- In early 2019, unofficial photos and videos appeared of a robot equipped with arms, then still referred to as "Cassie with arms". Digit was officially introduced to the world in mid-2019.
- The robot immediately attracted interest from logistics and service industries. Its slim silhouette, lightweight design, and dynamic gait indicated potential for work in warehouses, distribution centers, or as an indoor courier.
Partnerships and Further Development
- One important step in Digit's development was the establishment of cooperation with Ford in 2020. The automotive company saw an opportunity to test parcel delivery directly from autonomous vehicles, with Digit retrieving a package from the trunk and delivering it to the recipient's door.
- Agility Robotics continues to improve control and environment recognition algorithms so that the robot can not only walk and carry objects, but also avoid obstacles and engage in basic interaction with people.
Customer Cooperation and Vision for the Future
- The company states that Digit is already available in limited production for selected business partners and R&D centers. Future iterations are intended to increase payload capacity, extend battery operating time, and improve the robot's sensory functions.
- Agility Robotics expects humanoids of this type to relieve people from physically demanding tasks over the next few years, for example transporting goods within warehouses or performing simple assembly operations, in line with the global trend toward process automation and digitalization.
