Closed intramedullary nailing fixation is a method for treating fractured femurs with minimal invasiveness. However, this method lacks safety and precision. To avert prevailing problems such as extended cracks in the already broken bone, the design of a vibration damping robot and force evaluation system is essential. This paper present a sensor-based clamping robot system embedded with a regulated pressurized air balloon. Drilling forces were monitored by a force sensor attached to the end robot effector, while the reduced vibration result was measured by a non-contact laser displacement sensor. A two degree of freedom (2DOF) model was developed. Force and vibration data were obtained using a data acquisition module (EMS 309) and analyzed using MATLAB software (Version R2015b). Results obtained shows that both the frequencies and amplitudes of the vibration is reduced at 6 bar with effector’s spindle speed of 1500rpm. This proposed concept shows that drilling force and vibration can be reduced simultaneously using a robot effector coupled with a damper.
