Andrew+ robot executes experiments described in protocols designed with OneLab software. The same software is required to monitor the execution of such experiments. The communication between OneLab and embedded intelligence present in Andrew+ is achieved via ethernet or Wi-Fi connection.

It is also possible to partially control Andrew+ using the push button present on the forehead of the robot. In particular, according to the duration of pressure applied to the button, the status of Andrew+ can be changed. The table below summarizes the various possibilities:
