1. An electrosurgical connection unit for a surgical robot arm, the electrosurgical connection unit comprising:
an input port connectable to an electrosurgical generator, wherein when the input port is connected to the electrosurgical generation, the input port is configured to:
output one or more activation signals to the electrosurgical generator which cause the electrosurgical generator to output a driving electrosurgical signal configured to drive an electrosurgical instrument, and
receive the driving electrosurgical signal output by the electrosurgical generator;
an output port connectable to the electrosurgical instrument, the output port configured to output the driving electrosurgical signal received on the input port;
one or more activation switch units, wherein activation of an activation switch unit of the one or more activation switch units causes an activation signal to be output from the input port that indicates to the electrosurgical generator that a desired waveform is to be used to generate the driving electrosurgical signal; and
a control unit comprising a communications module connectable to a data communications network, the control unit configured to receive a control signal from an external computing device remote from the surgical robot arm over the data communication network and selectively activate one of the one or more activation switch units in response to the control signal.
