Why Boston Dynamics’ Atlas Humanoid Robot Grew a Head

Boston Dynamics spent years sending Atlas over boxes and through parkour courses with almost nothing on top that looked like a head. Hydraulic Atlas lived as a research machine built for flips, runs, and balance tests. Forward sensors were enough when the only job was reading the ground a few steps ahead.

Electric Atlas now has a new job that requires a robot with the ability to see beyond the immediate surroundings. Factories are typically a maze of people, carts, bins, and shelves, and a robot with a fixed stare will almost certainly run into people. As mechanical engineer Taylor Frey-Baker points out, it requires a broader view and a better sense of the room because it must work alongside humans rather than just carry heavy loads, and as a result of that shift in focus, a head and some cameras were added.

Cameras are mounted on heads for a reason: they keep them out of the way of arms and shoulders, which can otherwise block the vision. Aaron Abroff, the industrial design lead, likened it to volume mapping in 3D space, which would allow Atlas to view all of the fixtures, parts, and grippers at once. The neck joint may tilt slightly, about ten degrees, which is useful for gaining a better view of the floor or a tall shelf. It also gives a nice little nod when someone enters the area.

Turning and looking around are now part of the package. The head, torso, and limbs can all spin 360 degrees without any wires getting in the way. That’s a huge bonus because Scott Kuindersma has stated that wires can become damaged over time, and not having to deal with turns saves seconds on a line. It allows Atlas to take a good hard look behind it or set off in an entirely different direction without having to walk back and forth multiple times. Safety specifications now include 360-degree camera coverage as part of a safety system adopted from the world of self-driving automobiles, which is designed so that plant managers can sign off on the robot’s ability to recognize humans and hazards.

A full-fledged computer can be found deep within the robot’s shell. James Cuseo, who worked at Apple for 12 years before joining Boston Dynamics, claims that the head of the new Atlas is the most difficult object he’s ever built because it must stay cool, dry, and withstand a two-meter drop onto a table edge while carrying the weight of running the entire head. The computing parts are capable of being removed like a game cartridge. The entire head can even be unclipped, worked on at a desk, and then fitted back on, allowing you to upgrade the sensors and chips every year. With the head swappable feature, the corporation can continue to use the same old body while the head receives all of the enhancements.

The new Atlas has a completely different set of functions than the old one, as it must pick auto parts, sequence bins at Hyundai, and operate for four hours on a single pack. It must also be capable of lifting 50 kilogram loads in a single burst while remaining able to stop and start as someone walks across its path. The head houses all of the cameras, the computer, the lights, and the joint that controls them all. Swappable modules are important because they ensure that when the next version of the head is released, the rest of the robot does not need to be updated. That is why this machine, known for performing backflips, is now walking about the facility with a round glowing head that refuses to stop moving.
