Research
The lab work is the part of the company that makes a drone or a ground robot trustworthy enough for a defense, construction, or infrastructure buyer.
Autonomy
Perception, navigation, and control have to hold when GPS drops and the site does not look like the lab. The research question is the product requirement: keep moving, and hand the sticks back the moment a person asks.
Machines
Survey and reconnaissance from the air. On the ground, machines for the repetitive and hazardous parts of construction: finishing, handling, and the jobs that should not need a person in the hazard.
The stack
Deep tech here means the airframe, the avionics, the payload, and the algorithm are designed together. A change in the machine can be a change in the software, in the same building.
