We propose an algorithm used to obtain the information on stride length, height difference, and direction based on user's intent during walking. For exoskeleton robots used to assist paraplegic patients' walking, this information is used to generate gait patterns by themselves in on-line. To obtain this information, we attach an inertial measurement unit(IMU) on crutches and apply an extended kalman filter-based error correction method to reduce the phenomena of drift due to bias of the IMU. The proposed method is verifed in real walking scenarios including walking, climbing up-stairs, and changing direction of walking with normal.

A force sensor using strain gauges is widely used in many mechanical measuring systems. A method of measuring force and contact point using two gauges is available although it rather limited to extension of micro scale measurement. In order to overcome this limitation and to maximize a precision of the strain gauge sensor, sensor structure was optimized. Also, we used Kalman filtering for increasing an accuracy. It significantly increase the signal to noise ratio and stability of the sensor. This force sensor using strain gauges will be applied to diverse fields such as inspecting a micro system or manipulating small devices.

In this work, a study on improving traversability of a quadruped robot in a 3D rough terrain is presented. The interaction between the robot and the terrain is analyzed. The analysis shows that the traversability of the robot can be significantly improved by carefully considering the position and orientation of the robot's body in each step. The effectiveness of the proposed algorithm is verified in both simulation and experiment.
