A Study of Omnidirectional Quad-Screw-Drive Configurations for All-Terrain Locomotion

The article experiments an already existing double screw propelled vehicle and adds two more screws to create a quad screw propelled vehicle for better maneuverability. The experiment is conducted in different terrain conditions such as soft grounds and water to test not only the maneuverability but also whether the vehicle is amphibious or not.

While this article only adds two more screws to the vehicle, it demonstrated how the vehicle can be even more effective than already existing double screw propelled vehicle. With its omnidirectional movement, the robot can even be more effective in maneuvering through sand and water.
