<p>The purpose of this paper is to design a path following control system based on the kinematics of the Lizard-Inspired Single-Actuated robot (LISA). LISA is a new type of robot that mimics the quadrupedal walking morphology of lizards with a four-bar linkage mechanism and can realize both propulsion and turning with 1 degree-of-freedom. To achieve this purpose, this paper takes 3 approaches: kinematics formulation, control system design, and numerical simulation. In the kinematics formulation, we formulate LISA’s turning angle, stride length, posture, propulsive direction, curvature, and position coordinate. In control system design, we design a control system that converges not only distance error but also the posture error and control input. Conditional equations that can achieve these 3 control targets are formulated using forward kinematics and reference path functions, and control inputs are obtained by solving the inverse problem. Numerical simulations verify the effectiveness of the designed control system using 3 types of trajectories: linear, circular, and a combination of circular and linear trajectories. As a result, it is confirmed that the designed control system is effective for all 3 types of trajectories and that not only the distance error but also the attitude and control input can be converged.</p>

The risk of developing esophageal cancer from Barrett's Esophagus (BE) is associated with its size. However, the study to measure BE area is not advanced well. In this paper, we propose the method to measure BE area from one endoscopic image with camera distance. First, we assume that the esophagus is a cylinder and the camera is a pinhole camera because 3D reconstruction of no-feature points object like an esophagus is difficult. And then, we get BE area indirectly by calculating the surface area of this virtual cylinder. In measurement experiments, we used USB camera and cylinder phantoms to evaluate the accuracy of the proposed method. The errors were about 4-6% in the bottom area, about 10% in the side area, and about 1±2.5 mm in the phantom's height measurement.
