Automated Sensor Rig in Detecting Shape of an Object

In this paper an infrared sensor rig device is designed and developed. The ability of infrared range finder in measuring distance is applied to the sensor rig to detect lower limb shape model of prosthetic patient. Arduino is used as a microcontroller to control the whole system of this device with help from the stepper motor for the sensor rotation. Object shape is located at the center of the device and the minimum distance between object and sensor is fixed to 5 cm in order to reduce noise during data collecting. Data captured by the sensor is then saved in a text file for post processing using Matlab software. Various shape of objects have been tested and results obtained show that infrared sensor rig is capable to obtain shape data by plotting graph in 3D format.
