This paper describes a method of driving a rocker-bogie vehicle so that it can effectively step over most obstacles rather than impacting and climbing over them. Shocks resulting from the impact of the front wheel against an obstacle could damage the payload or the vehicle. For many future planetary missions, rovers will have to operate at human level speeds (~1m/second). When operating at low speed (greater than 10cm/second), dynamic shocks are minimized when this happens. However, when surmounting a sizable obstacle, the vehicles motion effectively stops while the front wheel climbs the obstacle. It is capable of overcoming obstacles that are on the order of the size of a wheel. The Rocker-Bogie Mobility system was designed to be used at slow speeds. ![]() The resolution of the cropped-image frame is the fundamental parameter in detecting path lines. The simulation result shows that the method is implemented properly, and the robot can follow a different type of path lines such as zigzag, dotted, and curved line. OpenCV and Python are utilized to design line detection systems and robot movements. The implementation of the robot is simulated using Webots simulator. This includes image preprocessing such as dilation, erosion, Gaussian filtering, contour search, and centerline definition to detect path lines and to determine the proper robot action. This paper proposed a method of image preprocessing along with its robot action for line-following robots. The camera installed on the line following robot aims to detect image-based lines and to navigate the robot to follow the path. Robotic vision is a robot that can obtain information through image processing by the camera. However, it is irrelevant, along with the development of autonomous vehicles and robotic vision. The most widely used sensors for the robots are photoelectric sensors. Line following robot is one of the popular robots commonly used for educational purposes. Experimental findings from simulations and real-world settings showed the efficiency of using synthetic datasets in mobile manipulation task. The proposed system has been experimentally verified and discussed using the Husky mobile base and 6DOF UR5 manipulator. Second, the execution step takes the estimated pose to generate continuous translational and orientational joint velocities. First, a perception network trains on synthetic datasets and then efficiently generalizes to real-life environment without postrefinements. The developed system consists of two main steps. ![]() The proposed system integrates (1) deep-ConvNet training using only synthetic single images, (2) 6DOF object pose estimation as sensing feedback, and (3) autonomous long-range mobile manipulation control. Then, it is integrated into a 3D visual servoing to achieve a long-range mobile manipulation task using a single camera setup. In this paper, a deep-ConvNet algorithm is developed for object pose estimation. Incorporating the estimated pose into an autonomous manipulation control scheme is another challenge. However, visual pose estimation of target object in 3D space is one of the critical challenges for robot-object interaction. The goal is to accomplish autonomous manipulation tasks without human interventions. The fourth industrial revolution (industry 4.0) demands high-autonomy and intelligence robotic manipulators.
