Apptronik’s current robot is Apollo 2, which the company unveiled on June 30 in bipedal and wheeled versions. Apptronik describes Apollo 2 as a data-collection and training platform. In the same announcement, it said its next commercial product will be Apollo 3, which will be built on what Apollo 2 learns. Apollo 3 has no published specifications.

Apollo 2 is also older than its public debut. Apptronik says it “has been the workhorse behind Robot Park for more than a year already,” which places it inside the company’s Austin training facility by mid-2025.

Where Apollo started

The first Apollo, unveiled in August 2023, came with a short spec sheet. Apptronik lists it at 5 feet 8 inches (1.72 meters), 160 pounds, able to lift 55 pounds and running four hours per battery pack. A 2024 GXO release said it was driven by linear actuators that mimic human muscles, with a force control architecture and a flexible safety zone perimeter for working near people.

What Apptronik says about Apollo 2

The Apollo 2 page makes four main design claims.

  • Mobility. A bipedal configuration for spaces built for people, and a wheeled base “for high-throughput environments.” Apptronik says the wheeled version is designed to conform with existing safety standards for industrial mobile robots. It does not name the standard.
  • Actuators. “Patented actuator technology” designed for “90%+ energy efficiency,” simple maintenance and mass manufacturing, and for reducing dependence on single-source suppliers. The page does not say whether these are the linear actuators described in 2024.
  • Power. Swappable batteries that Apptronik says “help enable 7x22 operation,” plus opportunity charging and tethering. No runtime per pack is given, so the 7x22 figure depends on how often packs are swapped and by whom.
  • Safety and signaling. An impact zone that pauses movement when an object enters a set radius, a configurable perimeter zone, and a chest display showing status, battery, charging and task progress. The radii are not published.

Above the hardware sit two software layers. Artemis handles perception, planning, controls, safety systems and task execution. Fleet Connect monitors robots, assigns tasks and collects data across a fleet. The intelligence comes largely from Google DeepMind: Apollo 2 data feeds Gemini Robotics models under a research partnership announced in December 2024.

What is missing

The Apollo 2 page lists no height, weight, payload, battery runtime, speed or price. The 55-pound payload and four-hour pack belong to the original Apollo and should not be carried over to the new robot. Apptronik also does not say how many Apollo 2 units exist. Its June release refers only to “operational fleets of Apollo 2 robots” at Robot Park and at customer and partner sites.
