You got to this planet somehow. That implies a highly advanced technological civilization. Why shouldn't you start with a bit of that advanced technology?
In this mod, you start the game with a limited number of extremely powerful devices salvaged from your crashed spaceship. All have an internal fusion power supply that can supply its own needs without electricity or fuel provided from the outside.
I intended each of these devices to do the following:
Reduce the tedium of the early game
Still incentivize the player to build additional infrastructure as quickly as possible.
Give a taste of the toys that await at the bottom of the tech tree.
Never become useless.
Practically speaking, the roboport and construction robots are significantly better than the construction robots you can eventually research. However, they provide and use much less power, making the starter roboport less effective than normal roboports once you have access to them. The starter robots can use normal roboports, but you start with a limited number and can never get more. Losses to biters or carelessly thrown grenades will deny you their use forever.
The mining drill and furnace are very fast, but have a limited inventory and do not output to belts, initially requiring players to manually remove and feed ore to maintain throughput. They can be automated with inserters, but there is very limited space for them, severely restricting throughput, although they get better as inserters improve.
