Bar Bending Simulator
All building constructions in India use construction rebars (steel concrete reinforcing bars) to provide structural reinforcement for concrete work. This necessitates experts in bending and cutting rebar to correctly size and bend the long steel rods before they can be installed. We developed a novel haptic based bar bending simulator with inputs from Larsen & Toubro’s (L&T) Construction Skills Training Institute (CSTI) for training novices in the construction rebar bending skill. The haptic training device is combined with a virtual environment and provides manual skill training and evaluation of trainees. The system provides a multi modal simulation environment with visual, audio and haptic feedback. Simulators are currently being used in training centers of L&T’s CSTIs, Chennai and Delhi.
