    A Case Study of Technology Transfer Process in a Government Research Organization in Sri Lanka
    (Technical Reports. Department of Management of Technology, University of Moratuwa Sri Lanka, 2015) Perera, H. S. C; Darshana, M; Liyanage, C
    The purpose of this paper is to identify and discuss the critical elements of a successful technology transfer process of a research organization by exploring the technology transfer process adopted by a leading government research institute in Sri Lanka. A field study based on a structured questionnaire and personal interviews was carried out to collect data. The study identified several factors that hinder a successful technology transfer as well as several facilitating factors. Findings reveal that contract research projects and funded projects have the greatest probability of commercialization success. It exposed that only 37% of the technologies that had received patents have been successful in the commercialization stage raising concerns about the research productivity. It was also found that the personal approach to technology transfer is dominating but dwindling compared with other approaches. Although the overall technology transfer success is about 86%, commercialization success is well below an acceptable level for this organization. Finally, this paper presents recommendations for an effective technology transfer process which can be applied for similar institutes.

    Electromagnetic Continuously Variable Transmission (EMCVT) System for Precision Torque Control in Human-Centered Robotic Applications
    (Multidisciplinary Digital Publishing Institute (MDPI), 2025-09-08) Madusankha, I; Jayaweera, P. N; Kahatapitiya, N. S; Sampath, P; Weeraratne, A; Subasinghage, K; Liyanage, C; Wijethunge, A; Ravichandran, N. K; Wijesinghe, R. E
    In human-centered robotic applications, safety, efficiency, and adaptability are critical for enabling effective interaction and performance. Incorporating electromagnetic continuously variable transmission (EM-CVT) systems into robotic designs enhances both safety and precise, adaptable motion control. The flexible power transmission offered by CVTs allows robots to operate across diverse environments, supporting various tasks, human interaction, and safe collaboration. This study presents a CVT-based mechanical subsystem developed using two cones and an intermediate belt-driven transmission mechanism, providing efficient power and motion transfer. The control subsystem consists of six strategically positioned electromagnets energized by signals from a microcontroller. This electromagnetic actuation enables rapid and precise adjustments to the transmission ratio, enhancing overall system performance. A linear relationship between slip percentage and gear ratio was observed, indicating that the control system achieves stable and efficient operation, with a measured power consumption of 2.95 W per electromagnet. Future work will focus on validating slip performance under dynamic loading conditions, integrating the system into robotic platforms, and optimizing materials and control strategies to enable broader real-world deployment.
