The ultimate goal of a single-wheel mobile robot is to maintain balance and to navigate on its terrain autonomously. To become an autonomous vehicle, it is required to stand up and drive by itself. In this paper, a controllable balancing angle of the single-wheel mobile robot, GYROBO developed previously, is found by empirical studies. A dynamic equation of the gyroscopic effect between a gimbal and...
In this paper, experimental studies on designing Q filters in the disturbance observer (DOB) based motion control for balancing a one-wheel robot are presented. The robot is simply modeled as a second order system and the corresponding Q filters are designed to form a DOB control structure. Two Q-filters such as Q20 and Q31 are investigated and analyzed in a view point of disturbance rejection performance...
Gyroscopically manipulated lateral motion of a single-wheel based robot system has a parametric oscillation problem. In this paper, we analyze the stability regions for balancing the single-wheel robot system and then propose how to determine the offset range of its suppression controller. Since the roll motion is coupled with the pitch motion, the parametric oscillation problem should be analyzed...
In this piece we take a brief peek at the possible world of robotic companions. In such a world, robots are adopted as butlers in our homes, as baby watchers, as friends and in general as life companions. For example, Helen lives with a robotic companion named Schpuffy. In the morning, Schpuffy checks Helen's schedule and finds out she has an appointment with a neighbor to take a walk at 8:30 a.m...
This paper discusses the use of a mobile robot following a person. It focuses on the less researched interaction with the human attitude through robot movements. The reward, which indicates the attitude of the human, is used to train the network so that the robot learns an appropriate position relative to the person. The algorithm presented in this study overcomes the difficulty that the feedback...
A fast single-view approach to determining the robot location by using a known-radius cylindrical object is proposed. In the approach, no prerequisite intrinsic camera parameters are imposed, and only 3D vector algebra is used in calculating the robot location. Therefore, alignment error can be avoided, the time of location determination is approximately 0.3 s, and the measurement error is less than...
