ASV Jetyak Karusell
The Jetyak is a kayak with a gasoline engine that can be radio controlled or operated autonomously. AUR lab is in charge of enabling it for different marine research activities. The resource is shared with the Arctic University of Norway in Tromsø.
The vehicle can be deployed with a land or ship crane with a minimum weight capacity of 500kg. Alternatively, there is a trailer for beach deployements. An ideal beach for deployment should have a smooth transition into the water, preferably without much wave activity, not very soft bottom but also not very rocky. It is important to consider that, at a minimum, 1 person needs to get in the water and might need special clothing.
Different modules can be fitted into the two moonpools of the vehicle. Depending on the applications, we build the modules to fit the sensors to equip the Jetyak with.
A pilot with a radio controller can manually operate the Jetyak from the distance, as long as it sees it. Navigation in the dark is aided by standard nautic lantern color code. It is also possible to operate it from a computer based station and with a Joystick. GPS-aided positioning and a radio link between the vehicle and the computer aid navigation in this case. Finally, a waypoint-based route can be programmed on the vehicle for it to operate autonomously. Note that it is not capable to identify and avoid obstacles.
