Agility Robotics’ humanoid robot underwent a rigorous strength test by performing a deadlift with a load of 65 pounds (approximately 29 kilograms). This presented both a structural and programming challenge. While the strength of the actuators was crucial, advanced coordination of the entire “body” played a key role in enabling the machine to dynamically respond to changes in the center of gravity. The choice of a deadlift exercise by the engineers from Oregon was not arbitrary. This exercise engages nearly every muscle group in the biological world and in robotics, demands perfect synchronization of arms, legs, and torso. Each upward movement involves thousands of real-time calculations to maintain stability and prevent the machine from tipping over.
The success secret of Digit lies in its training process based on advanced simulations. Rather than risking damage to expensive equipment in the laboratory, engineers first train the robot’s “brain” in a virtual environment. There, the digital counterpart of Digit lifts virtual weights of various masses and center of gravity distributions thousands of times. This enables the system to learn how to correct posture, grip firmly, and balance the torso even before the real robot encounters physical loads. This approach moves away from rigid manual motion programming towards flexible principles, allowing the machine to “feel” the weight and respond to it naturally.
The machine is designed for heavy, repetitive work in industrial settings. The latest iteration of the robot brings a series of enhancements aimed at making it an essential component of modern logistics. In Agility Robotics’ vision, Digit complements Autonomous Mobile Robots (AMRs). While the carts handle transporting goods over long distances, Digit takes over the most precise tasks such as picking packages from shelves, stacking them, or loading carts. The entire operation is monitored by the cloud platform Arc, enabling the management of the robot fleet from a single location, ensuring maintenance and task coordination.
Digit’s strength demonstration is a clear indication that the Chinese do not hold a monopoly on making an impression in the robotics industry. Agility Robotics has just laid another brick in the future where robots will perform heavy tasks in factories, allowing humans to focus on less physically demanding activities. Of course, as usual, this was a demonstration under tightly controlled conditions, so it will take some time before commercial machines become equally robust.
