In recent years the use of personal robotic platforms and their applications increased significantly. Among the various disciplines of engineering, currently mechatronics and robotics are among the most popular and most promising in the industrial field. Mechatronics brings together disciplines such as mechanics, electronics, industrial control and computation. On the other hand Mechatronics and robotics can be a useful means to increase the motivation of students and workers in their training process. In this regard, this paper presents a new multidisciplinary approach with focus on project oriented and hands on learning in advanced mechatronics course. this method will satisfy the requirement of modern technological society and industry. the implementation of the proposed method for a few semesters shows that students are so interested in such a method which leads them to learn more and steadily.

the dynamic coverage procedure for a group of non-holonomic agents in 3D unknown environment is studied in this paper. First, the chained model of the system is exploited. then, a cost function which its efficiency is proved by Lyapunov function in order to obtain control inputs is proposed. Besides, the reachable set for each agent is derived according to obtained control inputs and is applied to the group. Finally, the simulation results illustrate the performance of the suggested algorithm.

Pneumatic artificial muscles are widely used in the field of robotics in the development of robot manipulators to help or assist human beings. this can be attributed to their inherent compliance and low cost. However, their highly nonlinear dynamics and their time varying properties, make it challenging for classical controllers to accurately control such systems. Sliding mode control is a powerful tool to overcome control problems related to highly nonlinear systems that features robustness against modeling uncertainties, parameter variations and external disturbances. this paper investigates the use of discrete time sliding mode control for position control and trajectory tracking of a robot manipulator actuated by pneumatic artificial muscles. First and second order discrete sliding mode controllers are designed to make the joint angle track a desired angular position or trajectory within a guaranteed accuracy. A comparative study is presented along with simulations results.
Nowadays, physically impaired people (or people with special needs) still struggle with daily tasks when using mobility aid devices, whether for crossing doors, parking or manoeuvring. In this context, assistive robot...

In order to reduce the design flaw and improve the productivity, the model of LED bulb assembly line based on the Fuzzy Hierarchical Petri Net is proposed. the process of LED bulb assembly line is given, and the hierarchical modeling based on FHPN is described. the model of LED bulb assembly line includes three layers and each layer is defined. through the analysis of the time performance of the model based on FHPN, the optimization model of the LED bulb assembly line is put forward. the experimental result shows that the takt time of the optimization model decreases by 13.3% compared withthat of the original model, which increases the production efficiency rate.

this paper presents and evaluates a Skill Based Architecture withthe aim of increasing flexibility of dual-arm robot programming. the proposed architecture allows absolute control of the execution, easing coordination of the arms if necessary. this work try to quantify the advantages of the proposed paradigm based in different indicators. A pilot station is under development at Airbus Operations plant in Puerto Real, Spain. A real operation, drilling deburring of composite parts, has been selected as use case for evaluation.
