# 2.3 The Physical Challenge

In Njord’s physical autonomous challenge teams will have to design and build an autonomous surface vessel. The teams will make a design of their own which satisfies the technical specifications. In the physical challenge we encourage teams to take use of the Gemini simulator in order to test their guidance system. You can find the technical specifications for the physical challenge [here](https://njord.gitbook.io/physical-competition-2022/).
