Small robots

Most kinds of robots in researches are in solid structures. In these models, Euler-Lagrange method is easily used to obtain dynamic equations for simulation and obtaining controllers. But, actually, there is always flexibility - even very small or remarkable – in all kinds of robots. This research solves a problem in modelling a complex robot with a flexible link-flexible inverted pendulum- by presenting a method to simplify that robot.

In this paper, we consider the adaptive sliding mode control with radial basis function neural networks for the Omni-directional mobile robot. This is a holonomic robot that can operate easily in small and narrow spaces, due to the ability of flexible rotational and translational moving, simultaneously and independently.

Nowadays, there are numerous ways to configure trocar placements for lobectomy using the Da Vinci Xi system. Cho Ray Hospital conducted robotic video-assisted thoracic surgery (rVATS) lobectomy in July 2018 and obtained satisfactory results. Currently, there is no research on rVATS lobectomy in Vietnam, so we decided to report our initial experiences using rVATS lobectomy in non-small cell lung cancer at our institute.

This thesis presents an evaluation of the mapping performance of a variety of SLAM algorithms that are freely available in the Robot Operating System (ROS), in conjunction with ranging data from various ranging sensors suitable for use onboard small UAS. To compare the quality of the generated maps, an existing metric was initially employed, however deficiencies noted in this metric led to the development of two new metrics. A discussion of both the existing and new map quality metrics, and the advantages and disadvantages of each, is presented as part of this thesis.

In this paper, we design a controller based on hedge algebras for serial robots. The control rule is given by the linguistic rule-based system. The goal is to accurately control the moving robot arm which adheres given trajectories. Optimization of fuzzy parameters for the controller is done by genetic algorithms. The system has been simulated on the Matlab-Simulink software. The simulation results show that the tracking error is very small. Moreover, the controller worked well with correct control quality.

The IRB 1200 has no offset in axis two - an innovation that results in a longer stroke than other small robots, meaning it can be placed very close to the work piece and still be functional. One particular benefit of this long stroke is that it allows for a much more compact installation when the robot is mounted on the ceiling inside a small cell, such as in electronics machining or polishing applications. The robot’s large useable working area contained in a small package leads to shorter cycles and more compact machines.

This paper is devoted to the design of improved path finding algorithm that will find the near optimal path in a short time. The improved iterative RRT with path smoothing algorithm is developed and implemented in RoboCup Small Size robots. Through simulation it was shown that this algorithm can efficiently find desirable and near optimal solutions in short time.

This paper proposes a new way to optimize the biped walking gait design for biped robots that permits stable and robust stepping with pre-set foot lifting magnitude. The new meta-heuristic CFO-Central Force Optimization algorithm is initiatively applied to optimize the biped gait parameters as to ensure to keep biped robot walking robustly and steadily.

Inventions in steam engines, cotton mills, and iron works converged in the eighteenth century to propel the First Industrial Revolution. Inventions in internal combustion engines, electrification, and steelmaking in the nineteenth century ushered in the Second Industrial Revolution. Today, twentieth-century inventions in digital technology are being conjoined with twenty-first-century innovations in software, materials and advanced manufacturing processes, robotics, and web-based services to inaugurate the Third Industrial Revolution.

Engineering is a subject that ranges from large collaborations to small individual projects. Almost all engineering projects are beholden to some sort of financing agency: a company, a set of investors, or a government. The few types of engineering that are minimally constrained by such issues are pro bono engineering and open design engineering.
