Short clip of Underwater Tracked vehicle with multiple view
Two 5dof hobbyist robot arms are used in this project. Servos used are digital servos with feedback wire. User's hands position is sent to Arduino Mega for computation. The positions of hands are translated to robot joint angles using inverse kinematic function. Two webcams are placed aboce the robot to provide stereoscopic vision back to VR headset
Telecontrol of hobbyist robotic arm using VR
A high resolution camera with minimal distortion is used in this project. Camera calibration is performed using OpenCV to obtain  extrinsic and intrinsic parameters. The objective is to detect impurities with size up to 20micrometer (detectable in pixel) and guide the suction pin to coordinates of impurities. 
item used:
1. Matrix Vision camera
2. Delta Electronics servo AC motors
4. SMC pneumatic parts
High Precision Cartesian Robot with Suction for food cleanin

Publications

Development of ROV based Water Tank Cleaning Robot

Jurnal Teknologi, 72(2)
In this paper, an alternative cleaning method using a Remotely Operated Underwater Vehicle (ROV) is proposed. Using ROV, water supply disruption can be prevented and cleaning process will be more efficient and cost effective.

Task learning utilizing curve fitting method for kinect based humanoid robot

2014 IEEE International Conference on Robotics and Biomimetics
In this paper, human mimicry as a teleoperation method is presented using a semi-humanoid robot, with Microsoft Kinect sensor as its interface. Vector calculations are used to obtain joint angles of human body to be imitated by the humanoid robot, focusing on upper body imitation. Then, a task learning methodology is proposed for the humanoid robot to carry out a task independently by using curve-fitting method.

Interactive knee cartilage extraction using efficient segmentation software:

International Conference on Biomedical Engineering and Biotechnology 2014
In this paper, we propose an interactive knee cartilage extraction software that covers three important features: intuitiveness, speed, and convenience. The segmentation is performed using multi-label random walks algorithm.

Medical Image Contrast Enhancement Using Spline Concept: Data from the Osteoarthritis Initiative

Journal of Medical Imaging and Health Informatics, Volume 4, Number 4, August 2014, pp. 511-520(10)
In this work, we propose to implement cubic spline to reduce the difference in pixel intensity prior to histogram equalization while retaining the partition of histogram to prevent dramatic mean brightness shift in resultant image.

Medical Image Visual Appearance Improvement Using Bihistogram Bezier Curve Contrast Enhancement:

The Scientific World Journal, vol. 2014
In this work, the proposed bihistogram Bezier curve contrast enhancement introduces the concept of “adequate contrast enhancement” to overcome sudden jump problem in knee magnetic resonance image. The proposed method improves tissue contrast and preserves pertinent knee features without compromising natural image appearance.
