How it works on your site

The Exosystem is a retrofit autonomy kit that installs on the tail of a standard mid-size excavator, converting it to supervised autonomous trenching for solar farm electrical infrastructure. It handles survey, excavation, and grade checking without an operator in the cab; a Robotic Equipment Operator (REO) supervises multiple machines remotely from a nearby trailer. One REO running multiple excavators simultaneously delivers a 45% productivity gain over single-operator trenching, as reported by ENR on Bechtel solar projects. The Exosystem has been shipping since 2021, with production deployments across utility-scale solar and energy pipeline projects in the US and Australia.

Trenching (Utility Excavation)

The Exosystem follows pre-loaded GPS trench lines without physical stakes, executing the dig-and-grade cycle autonomously while the REO monitors from a trailer. The excavator handles survey, excavation, and in-trench grade checking as a continuous workflow; manual operation is preserved and the kit is fully reversible. Compatible with Caterpillar, Komatsu, Hitachi, John Deere, and Volvo mid-size excavators.

Field outcomes

1 of 2
  1. Exosystem

    Bechtel used Built Robotics' Exosystem to run Komatsu and Caterpillar excavators autonomously, digging ditches for electrical lines and pile holes on large solar farm projects in Texas and Louisiana, reaching 93% uptime and a 45% productivity increase over a single operator.

  2. Exosystem

    MPC Kinetic began digging pipeline trenches across Queensland's Surat Basin with fully autonomous excavators guided by Built Robotics' Exosystem, after a late-2019 trial of a 30t excavator.
