Innovations in Intelligent Systems

Projects in this theme focus on the design of complex engineering systems for special missions on land, water, air, and outer space. The theme began in 2012 with development of satellites and other special space missions. It now also includes autonomous underwater and surface vehicles, as well as unmanned aerial vehicles.


Bumblebee Autonomous Systems

Many organisations operate in the harsh marine environment, such as research institutes, oil and gas companies and defence corporations. Traditionally, these organisations have used manned vessels to duel with the seas as well as the underwater domain. Such methods were successful, but they were inefficient, dangerous and costly. Our team has done research on the operations of such organisations and we propose the use of unmanned and autonomous systems as a solution.

Satellite Agricultural Remote Sensing System

Precision agriculture is the use of technology to enable better decision making and optimized use of resources for farming. In this regard, satellites are an effective way to observe large plots of crop. However, typical satellites are expensive to build and launch, and have lengthy development periods. On the other hand, nanosatellites are increasing in popularity due to the use of commercial components and “fly-learn-refly” approach which lower cost and speed up development.

Nano-Satellite Attitude Determination & Control System

The Attitude Determination and Control System (ADCS) is responsible for determining and manipulating the orientation of the satellite in space. ADCS uses a variety of sensors and active actuators to give a flexible control in orienting the satellite in addition to a faster and more stable de-tumbling.

Total Electron Content Payload for Nano-Satellite

The Total Electron Content (TEC) is defined to be the total number of electrons along a path between two points, which in this case is the satellite and ground station. TEC measurement is important for the correction of propagation effects on applied radio systems such as the Global Positioning System (GPS). The TEC payload is a part of NUS' first nano-satellite 'Galassia' developed by undergrad students.

Low Cost Radar for Short Range Application

High resolution radar has become an interesting topic among researchers recently, for their ability to detect moving or static objects in short distance, and possibility in developing into a SAR system. However, the radar systems presented in market are either too expensive due to redundant features for research usages, or come in a sealed box, with little feasibility for further improvement and modification. The solution we proposed is low cost, and easy to modify.

Cost-Effective High Resolution Camera for CubeSat

Earth Observation using CubeSats is witnessing an increased demand due to lower operation costs and shorter development time compared to traditional satellites. However, the current CubeSat camera modules lack the high resolution required by its applications. This project uses commercial-off-the-shelf components to develop a cost-effective camera module for Earth Observation with CubeSats.


Bumblebee is a student-run, multi-disciplinary robotics team with students from both the Faculty of Engineering and School of Computing. The Bumblebee team designs and builds Autonomous Underwater Vehicles (AUVs) and Autonomous Surface Vessels (ASVs) to navigate across oceans independently, from the shore line and the water surface, to deep waters.

High Data-Rate Transmitter for CubeSats

Communication systems for CubeSats still lag behind those for larger satellites. The downlink rate of most CubeSats is limited to few kilobits per second while the norm for traditional satellites is hundreds of megabits per second. This project develops a low-cost CubeSat transmitter with a data rate comparable to those on larger satellites.
