Team NUS UAV in AVIC Cup

 

The NUS UAS Group from the National University of Singapore (NUS) has participated in the 2nd AVIC Cup International UAV Grand Prix, which was held in Beijing, September, 2013. In this competition, the group competed with a total of 120 teams from various universities, as well as civilian and military research institutes such as the Chinese Academy of Sciences, Tsinghua University, Beijing University of Astronautics and Aeronautics and Nanjing University of Astronautics and Aeronautics.

In the Rotor-Wing Prix, competitors had to perform several tasks using a rotorcraft such as a helicopter. The UAV has to be fully autonomous when performing a list of tasks, like navigating to a moving ship and transferring the buckets on its side to another moving ship. In the Creativity Prix, competitors had to design a new type of aircraft and to prove that it works. To know more about this competition: research project UAVGP.

The team has won the 1st place in the final round, and also the overall 2nd Place in the Rotor-Wing Prix. They have also won the New Innovation Star Prize in the Creativity Prix. Their achievements are also featured in NUS website.

Competition Tasks

 

Rotor-Wing Prix

In the Rotor-Wing Prix, competitors had to perform several tasks using a rotorcraft such as a helicopter. The UAV has to be fully autonomous when performing a list of tasks, like navigating to a moving ship and transferring the buckets on its side to another moving ship. Specifically, the team is required to perform the following tasks in fully autonomous control.

autonomous take-off

navigation to a target ship

picking up bucket from the target ship

dropping of bucket to the next ship

autonomous landing

In order to complete the tasks, a UAV is designed based on Raptor 90 airframe. The UAV codenamed NUS²TLion has the capability of completing the given tasks using a servo commanded mechanical claw in autonomous fashion.

We are the only team who complete every given tasks in the final round of the competition on the moving ship platforms.

 

 

 

 

 

Creativity Prix

In the Creativity Prix, competitors had to design a new type of aircraft and to prove that it works. An unconventional reconfigurable hybrid UAV, named ULion (NUS²TLion2), was designed for the competition.

The platform primarily is able to perform vertical take-off and landing while transforming into fixed-winged mode to enhance flight efficiency and endurance. It has unique features such as the vector-thrust contra-rotating motors and adjustable canards to achieve stable hovering control and a 4-bar linkage mechanism which allows the folding of its wings, resulting in a compact platform design. The platform also features automatic adjustment of the centre of gravity while switching between modes to improve overall stability.

Our team is one of the few teams that could achieve safe take-off, level flight and landing while exhibiting the innovative features of our platform.
