A few good Colonies of Mars

Remember how the Europeans colonized Americas,Asia and Africa something similar is needed but without an unwelcoming local population but otherwise.
Although mars doesn't have any of them if we keep aside the claims by our over enthusiastic alien theorists for a second so what should we do? as we don't have a local population we would need to build them this time which is no cherry picking.
However some basic steps needed to colonize a new world beyond our little blue world would require the following
Galleons of our time:First thing is a space ship which can travel to mars in less than a financial quarter without letting the astronauts getting fried up by deep space cosmic radiation which currently seems unlikely to be achievable in next 15 years depending upon on the technological advances made public till now.
So lets assume that this issue has been taken care of by 2030 then the next thing which should be taken care of is Ports of space more so space stations to dock the ships which needs to parked in the martian orbit now the question is how do you do that?

The Answer is simple which is to send a large space station assembled in advance over the earth i.e. to say lower earth orbit. and then tow it with an attached space booster Rocket.

Then the next step will be to send in as many robots as possible may be even thousands with building capabilities and surveying capabilities and and all sort of capabilities to the martian surface via this space station(lets call it mars orbital space port or station) who after selecting a site will meticulously work and design structures on the spot using 3D printers and on site assembly lines for the human arrival.
Along with these robots we would need to send in plant species which will help create a breathable environment for us within the structures after testing their own chances of survival are confirmed if any in artificial environments designed and built by the robots with required nutrients (if needed) and all this will take another 10 years (space module construction in lower earth orbit included) if not more as currently technologies for all this are not available.

After the completion of living quarters and after thorough testing of 5 to 6 more years we can possibly have A True Mars Mission if any because by then we would have a present day equivalent of European galleons and a space port to dock our ships and the most important thing a honest and hard working local population in the form of robots hugging green plants waiting for their masters to live with them happily ever after or do they?
