API Compatibility

Interfaces with any product that has an API
Our robot API is open-source and users can make adjustments to the software as needed to interface with other products. While all integrations are possible, they all require custom code work i.e. most customers will need to write custom libraries and install software packages that are not shipped with the robot.
Open-source APIs GitHub.
