The touch panel used for this experiment is the WEINTECH MT6071iE. The six-axis robotic arm was controlled by an AT90CAN128, manufactured by the ATMEL Company. A DGServo servomotor was used to drive the robots joints, which consisted of four servomotors with 12 kg torque, two 1.8 kg servomotors with reduction gear, and some precision aluminum alloy components. Driven by the servomotors, the robotic...
In this work, ultrasonic sensors are adopted to implement a real-time obstacle avoidance system for wheeled robots, so that the robot can continually detect surroundings, avoid obstacles, and move toward the target area. Secondly, six ultrasound sensors installed on the wheeled robot were utilized to detect large obstacles and to obtain distance information between the robot and the obstacle. The...
Path planning is one of the critical issues in mobile robot applications. Traditional methods for path planning in unknown dynamic environment generally plan one step rather than multiple controlling steps. This paper proposes an approach with multiple controlling steps which integrates receding horizon control (RHC) for mobile robot path planning in which the obstacle avoidance problem is converted...
Relative coordination has predominant advantage in uncertain environment path planning problem because it denies much of redundant information of the dynamic environment while avoids the rotation transformation which is a big burden in the traditional methods. Based on relative coordination, this paper proposes a trimmed Ant Colony Optimization (ACO) algorithm for three dimensional trajectory generation,...
An omnidirectional vision-based localization method based on the particle Alter is proposed to achieve the location of robot on a soccer field in this paper. Two kinds of sensor information are considered in the method to let the robot on the soccer field can estimate its location and then to decide an appropriate strategy. One is the robot action sensor information obtained by the motor's feedback...
In this paper, we present our preliminary report in applying formal verification to the design process of robotic systems under dynamic environments; the goal is to complement existing testing or simulation techniques by experimenting an adaptable framework, where verification models with tamable complexity are generated from the simulation model. Our targets are robotic systems with shape-adjustable...
In this paper, an interval type-2 fuzzy kinematic control (IT2-FKC) combined with an interval type-2 adaptive fuzzy sliding-mode dynamic control (IT2-AFSMDC) are proposed for controlling the trajectory-tracking of a nonholonomic wheeled mobile robot (WMR). Firstly, an interval type-2 fuzzy logic controller designed for the kinematic model of the WMR is introduced, and then the IT2-AFSMDC is developed...
The motivation of this paper is to confer the study of omni-directional trajectory motion control implemented by the SOPC system. In the hardware architecture, four mutual orthogonal omni-directional wheels are horizontally established on the plane of the chassis and four optical encoders are equipped with DC motors to read the data of angular velocity and compute the posture of the surveillance and...
This paper describes robots with object-oriented peripheral modules that are controlled by a personal single board computer (PSBC). In addition, the applications of the PSBC and related peripheral modules are also described.
