  • 3D Environmental force : position impedance variation for different motion parameters 
    Ruwanthika, RMM; Harsha, AM; Abeykoon, S [Conference-Abstract]
    The skill preservation of an expert has been a serious problem for countries with aging population because decrease of the number of successors. The concepts of haptic database and force sensor recorder which have been ...

    The skill preservation of an expert has been a serious problem for countries with aging population because decrease of the number of successors. The concepts of haptic database and force sensor recorder which have been ...
  • computer vision based fire alarming system 
    Gunawaardena, AE; Ruwanthika, RMM; Jayasekara, AGBP [Conference-Full-text]
    Fire detection system in the surveillance system monitors the indoor environment and issues alarm as part of the early warning mechanism with ultimate goal to provide an alarm at early stage before the fire become ...
  • Potential for improving green roof performance through artificial irrigation 
    Heendeniya, HKCB; Ruwanthika, RMM; Jayasekara, AGBP [Conference-Full-text]
    Historically extensive green roofs were designed for natural precipitation with a plant selection focusing on hardy succulents such as sedums that can survive harsh, water stressed conditions. Although this seems a ...
  • Reaction torque observer based force feedback gripper with force lock 
    Ruwanthika, RMM [Thesis-Full-text]
    Haptic information is a bilateral information of the law of action and reaction. Most of the researchers have done experiments on bilateral teleoperation but still they haven’t given much attention on force lock during ...
  • Simulation of enhanced force limiting gripper for bilateral teleoperation 
    Ruwanthika, RMM; Abeykoon, AMHS [Conference-Abstract]
    This paper proposes an enhanced force limiting gripper to avoid object deformation when it is in contact with the slave due to excessive forces imposed by the master operator in bilateral control. The force lock protects ...
  • Vibro-haptic white cane with enhanced vibro sensitivity 
    Abeysiriwardhana, WASP; Ruwanthika, RMM; Abeykoon, AMHS [Conference-Full-text]
    The traditional white cane allows blind persons to understand the environment by tapping the white cane against the objects. It has limited capabilities in detecting objects far from the person. Available electronic blind ...
