Designing the self-balancing two-wheeled mobile robots and reducing undesired vibrations are of great importance. For this purpose, the majority of researches are focused on application of relatively complex control approaches without improving the robot structure. Therefore, in this paper we introduce a new two-wheeled mobile robot which, despite its relative simple structure, fulfills the req...

The development of microrobots on a millimeter scale has recently received much attention. The environments in which these robots are supposed to operate are narrow and potentially complicated spaces, such as micro-factory, blood vessel, and micro-satellite. The robots must have omni-directional mobility, high power and high load capacity, within a scale in millimeters, in order to accomplish t...

this paper aims to investigate a new and intricate behavior of immediate follower during the lane change of leader vehicle. accordingly, the mentioned situation is a transient state in car following behavior during which the follower vehicle considerably deviates from conventional car following models for a limited time, which is a complex state including lateral and longitudinal movement simul...

A current trend in the automotive industry is the application of joining techniques that contribute to lighter car bodies with higher stiffness, increasing at the same time the efficiency of the manufacturing process. An emerging technology is remote laser welding (RLW). It joins metal sheets by a laser beam, projected from a scanner mounted on an industrial robot. This enables contactless weld...

This work addresses the pursuit-evasion problem of capturing a Differential Drive Robot (DDR) with Dubins Car (DC) in minimum time. We model as zero-sum differential game, and using game theory, we compute time-optimal motion strategies players near end game. unveil existence three singular surfaces: an Evader’s Dispersal Surface (EDS), Transition (TS), where DDR switches its controls, Pursuer’...

This study presents the overall architecture of HeterBot, a heterogeneous mobile manipulation robot developed in our lab, which is designed for versatile operation hazardous environments. The most significant feature HeterBot design created by adopting idea ‘big arm + small arm’ and car mini car’. combination has advantage functional complementation, achieves performance promotion both locomoti...

When interacting with a new environment, a robot can improve its online performance by efficiently exploring the effects of its actions. The efficiency of exploration can be expanded significantly by modeling and using latent structure to generalize experiences. We provide a theoretical development of the problem of exploration with latent structure, analyze several algorithms and prove matchin...

This paper presents LQG-MP (linear-quadratic Gaussian motion planner), a new approach to robot motion planning that takes into account the sensors and the controller that will be used during execution of the robot’s path. LQGMP is based on the linear-quadratic controller with Gaussian models of uncertainty, and explicitly characterizes in advance (i.e., before execution) the apriori probability...
