This paper proposes a method to increase the impedance range of admittance-type haptic interfaces. Admittance-type haptic interfaces are used in various applications that typically require interaction with high impedance virtual environments. However, the performance of admittance haptic interfaces is often judged by the lower boundary of the impedance that can be achieved without stability problem;...
In robot-assisted surgery, haptic feedback is ongoing issue. The breaking of surgical suture material and the damage of tissue are avoidable with haptic feedback. This paper is proposing to add haptic feedback in the da Vinci like robot using unmodified da Vinci surgical instrument. To overcome the restriction of space and difficulty in measuring the force at the end-effector, the torque sensor-motor...
