Apptronik Apollo

A humanoid with published numbers

Apollo is a humanoid robot made by Apptronik. The company publishes a short, concrete specification for it: the robot stands 5 ft 8 in (1.72 m) tall and weighs 160 pounds, can lift 55 pounds, and runs for four hours on one battery pack.^[1][2] The same height, weight, runtime and payload figures are listed on Apptronik's homepage.^[1] Apptronik's news page dates the coverage of Apollo's unveiling to 23 August 2023.^[2]

Those four numbers describe a machine built to share space with people: it is roughly the height of an adult, and its lifting capacity is in the range of what one person can carry. That matters because a humanoid robot is meant to step into workplaces already arranged around human bodies — workbenches, shelves, aisles and vehicle cabins sized for people rather than for machines.

Electric power and a swappable battery

CNN reported that Apollo runs on electricity rather than hydraulics, and that its four-hour battery can be swapped out, which the report framed as allowing a 22-hour working day.^[3] The two design choices are connected: a battery pack that can be exchanged without long charging breaks turns runtime from a limit on the shift into a matter of how many packs are on hand.

CNN also reported that Apollo carries digital panels on its chest. These show the remaining battery life, the task the robot is currently doing, and what it will do next.^[3] For a machine working alongside people, that is a practical kind of communication: a colleague can see at a glance what the robot is about to do, without consulting a screen elsewhere.

Designed to work near people

Apptronik says Apollo uses a force control architecture to keep operation safe around people, similar to the way a collaborative robot works.^[2] Force control means the robot senses the forces acting on its joints and limbs and responds to them, rather than simply driving to a position and stopping there; the same idea underlies collaborative robot arms that are allowed to operate without a safety cage.

Apptronik also says the robot's modular design supports both bipedal and wheeled mobility options.^[2] A legged version can handle steps and uneven ground; a wheeled base is simpler and steadier where floors are flat. Offering both lets the same upper body be fitted to the environment a customer actually has.

Learning tasks instead of being programmed for each one

CNBC reported that the newest Apollo model is assisted by an AI data engine that lets it learn new tasks from foundational models trained on human demonstrations.^[4] Learning from demonstrations is a way of teaching a robot by showing it examples of a task — recorded from people doing the work — instead of writing out every motion by hand. A "foundational model" in this context is a model trained on a broad body of such data that can then be adapted to particular jobs.

Where the first jobs are

According to CNBC, Apollo's initial applications target warehouses and manufacturing plants, including trailer unloading, case picking and machine tending.^[4] These are the repetitive, physically demanding jobs that logistics and factories already struggle to staff: taking goods out of a truck trailer, picking cases of product for orders, and loading and unloading parts at a machine. All three take place in spaces built for people, which is the reason a human-shaped robot is one option being tried.

Where it sits

Apollo is one of a group of humanoid robots aimed at industrial work rather than at research demonstrations. Its published specification sets out what that ambition requires in practice: a body close to human size and strength, a power scheme that keeps it running across long shifts, a safety architecture that lets people work beside it, and a software path for picking up new tasks without being reprogrammed from scratch each time. Whether the four-hour pack, the force control and the learning pipeline add up to a machine that pays for itself is the question the first warehouse and factory deployments are meant to answer.
