A robot that works near people must know more than how to walk. It must know when to slow down, when to stop, and when a task should wait. Agility Robotics' recent look at Digit 5 puts that safety problem near the center of the product design.

The company describes Digit 5 as a humanoid robot with systems that detect when a person is close. When the robot senses a risky interaction, it can slow, stop, or shut down. That behavior may not look dramatic in a demonstration, but it represents a major shift in how students can think about success. The fastest robot is not necessarily the best robot if it cannot share space safely.

The reported design also includes modular hands and a lifting capacity of about 50 pounds. The hands can be changed for different tasks, much like a student team might swap a claw for a scoop or a gripper. The robot is also being designed for long work periods, with a recharge plan intended to support more than one shift.

A classroom version of the challenge could use a small wheeled robot and a cardboard workspace. Students could program a normal route, then add a safety zone around a person-shaped marker. The goal would be to compare a robot that follows its path blindly with one that changes behavior when the environment changes. That exercise brings together sensors, state machines, testing, and responsible design.

The capabilities and future availability described here are reported claims, not a guarantee of performance in every workplace. The recent Digit 5 report is the source for the product details discussed in this article.
