Use a compositional model instead of inheritance for Robot

At the moment we have to inherit from the robot class to allow us to write robots, this is a problem as it makes it much harder to unit test our robots. Could we not have an interface instead ? and expose the robot class more as a service ? So that we can inject it into our robots instead ? that would enable us to mock the cAlgo api, use ioc etc, you could even start splitting up the api, so we would only depend on what we needed ?
