Terrapin was the second installment, and had a more subtle exterior, compared to its predecessor.
Terrapin is Vortex's second ROV. The name comes from its resemble of the terrapin, a freshwater turtle. This drone took just as much time to develop and create as its predecessor, but was more cost efficient as 9000 USD was spent to build this brand new ROV, significantly less than Maelstorm.
This ROV improved its control and navigation compared to Maelstrom by increasing its amount of thrusters to eight and more than doubled its amount of cameras to seven. The drone also improved aesthetically by having the transparent cover that gives it the resemblence of a terrapin.
