Unmanned Surface Vehicle (USV)
The USV (BBASV 2.0) can operate independently and cooperatively to perform tasks remotely and autonomously on surface water. The motors are placed in vector configuration for holonomic drive, thus providing the vehicle with 4 degree of freedom (DOF). It also has a Launch and Recovery System (LARS) that allows for autonomous deployment of AUV from the ASV, allowing them to work in tandem. The vehicle is made to withstand up to Sea-state 3. The system of the vehicle can be easily configured to cater the specific needs of different stakeholders. The NUS Bumblebee USV team participated in the 2018 Maritime RobotX Challenge in Hawaii and emerged as Champions.
Autonomous Underwater Vehicles (AUV)
The AUV can be operated autonomously and remotely to perform tasks in the water with 6 degree of freedom (DOF), up to 100 meter deep. It has a front facing and bottom facing camera, along with a front facing sonar for long distance object detection. It navigate using its on board Inertia Measurement Unit (IMU), Doppler Velocity Logger (DVL), and Acoustics System. The vehicle is highly modular to be configured in order to cater the different underwater challenges. The NUS Bumblebee AUV team achieved second position at the 2018 International Robosub Competition held in San Diego, USA.
