In recent years, robotic research also focuses on the construction of human friendly robots, especially for home and service industries. With advancement in technologies, the robotic systems will be able to perceive the environments and act on a given task with capability on par or better than that of humans. A robot may also have the ability to move around in a given environment. Robotic systems may range from industrial robots, humanoid robots, mobile robots, biomimetic robots, flying robot, unmanned vehicles, etc. There are also wearable robotic system such as exoskeleton or assistive device which can be used for rehabilitation and enhancement of humans stamina and strength. In general, robotic systems can be applied to improve productivity, security and also to assist humans in challenging tasks.<\/p>\n<p><strong><u>Automatic Welding of Complex Joints with Thick Weld Volume<\/u><\/strong><\/p>\n<p>Fabrication of offshore oil rig structures is typically tedious and labour-intensive.\u00a0 It involves welding numerous joints as shown in the figure and multiple welding passes are necessary due large weld volume.\u00a0 In order to enhance the productivity in the yard, automation of such complex joint welding is highly desirable.\u00a0 This project aims to realise an automated welding system for such task using industrial robot with appropriate sensors.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\" \/wp-content\/uploads\/sites\/11\/2019\/02\/robotics1.jpg\" alt=\"Robotics1\" width=\"348\" height=\"195\" \/><\/p>\nChew Chee Meng<br \/>\nAssociate Professor<br \/>\nEmail:\u00a0\u00a0<a href=\"mailto:chewcm@nus.edu.sg\">chewcm@nus.edu.sg<\/a>\n<p><strong>Humanoid Robotics<\/strong><\/p>\n<p>Humanoid Robots have been successfully demonstrated to walk in level ground and regular steps or slopes.

To assist the patient to regain the walking ability, high intensity and task-oriented interventions after stroke could be given to him immediately after the stroke incident. In recent years, robotic lower extremity assistive devices have been used for gait rehabilitation training of stroke patients with successful outcomes. However, most existing devices are costly and bulky. Hence, their usage is limited in the hospital environment. Due to short hospital stay, most patients are not able to access to the hospital equipment regularly after they have been discharged. This may result in the patient being unable to achieve high level recovery due to the low access rate of the hospital equipment. Hence, there is a need of low cost home-based rehabilitation system for the patients to continue their rehabilitation at home. This has motivated us to develop low cost, light-weight and wearable lower extremity assistive device for home based gait rehabilitation.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\" \/wp-content\/uploads\/sites\/11\/2019\/02\/lower-extremity-assistive-device-1.jpg\" alt=\"Lower Extremity Assistive Device 1\" width=\"411\" height=\"550\" \/><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\" \/wp-content\/uploads\/sites\/11\/2019\/02\/lower-extremity-assistive-device-2.jpg\" alt=\"Lower Extremity Assistive Device 2\" width=\"264\" height=\"550\" \/><\/p>\nChew Chee Meng<br \/>\nAssociate Professor<br \/>\nEmail:\u00a0\u00a0<a href=\"mailto:chewcm@nus.edu.sg\">chewcm@nus.edu.sg<\/a>\n<p><strong><u>Unmanned Surface Vehicle<\/u><\/strong><\/p>\n<p>The purpose of this project is to explore low cost solution for obstacle and collision avoidance for USV based on low cost sensors (such as vision, GPS, IMU, etc).\u00a0 New algorithms will be implemented and tested on our physical surface vehicle.\u00a0 The algorithms should enable the vehicle to move from a start point towards an end point while avoid colliding with obstacles randomly placed between the start and end points.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cde.nus.edu.sg\/me\/wp-content\/uploads\/sites\/11\/2019\/02\/unmanned-surface-vehicle-1024x768-1024x768.jpg\" alt=\"Unmanned Surface Vehicle 1024x768\" width=\"500\" height=\"375\" \/><\/p>\nVelusamy Subramaniam<br \/>\nAssistant Professor<br \/>\nEmail:\u00a0\u00a0<a href=\"mailto:mpesubra@nus.edu.sg\">mpesubra@nus.edu.sg<\/a>\nChew Chee Meng<br \/>\nAssociate Professor<br \/>\nEmail:\u00a0\u00a0<a href=\"mailto:chewcm@nus.edu.sg\">chewcm@nus.edu.sg<\/a>\nMandar Anil Chitre<br \/>\nAssistant Professor (ECE)<br \/>\nEmail:\u00a0\u00a0<a href=\"mailto:tmsmac@nus.edu.sg\">tmsmac@nus.edu.sg<\/a>\n<p><strong><u>Effectively simultaneous localized manipulation of multiple magnetic micro-particles<\/u><\/strong><\/p>\n<p>The key challenge in manipulating multiple magnetic micro-particles individually and simultaneously lies on the ability to localize the magnetic field applied on an individual particle.

Empirical studies have revealed that driver behaviour plays a key role in the forming of traffic congestion. The effect of driver behaviour on traffic congestion is the most prominent in the dynamics of on-ramp merging, which is known to be one major cause of traffic congestion in large cities. Our research aims to develop an Assistive Ramp-Merging CONtrol (ARMCON) system to guide the on-ramp driver when merging with the main traffic on the express way in order to minimize the disruption of the main traffic on the express while a certain merging rate is maintained.<\/p>\nPeter C.Y.
