You can obtain this by building a Tractor (or any other mobile, Tractor is however easiest), which can be made via the Small Printer once you learn the blueprint for 1,000 bytes, and requires 2 Aluminium.
You'll also need a Rover Seat, which requires 2 Compound (no bytes required).
Attach the Seat to the Tractor and earn the achievement.
Edit: You don't actually need to make the Rover seat, as the Tractor has a seat built in. Simply building the Tractor itself will earn the achievement.
