Built Robotics
Exosystem: aftermarket retrofit kit (computer, sensors, hydraulic actuators) mounted on the tail of any modern excavator; follows pre-loaded GPS trench lines and executes dig-and-grade cycles autonomously while a Remote Excavator Operator (REO) monitors multiple machines from a trailer. RPD 35 pile driver uses sub-centimeter RTK GPS, IMUs, and laser rangefinders to pick, position, and drive piles autonomously; integrates survey, distribution, driving, and inspection into one uninterrupted workflow. Both products are RaaS and fully reversible.
