Juniper Publishers- Journal of Robotics Abstract Climate change and depletion of fossil fuel resources have led to the promotion of the use of Electric Vehicles (EVs). Since most EVs use Lithium Ion Batteries (LIB), we analyze the amount of lithium required by LIB for powering electric vehicles in a scenario where all fossil fuel powered passenger cars are replaced by EVs. Based on the current proven reserves of lithium and existing production rate of passenger cars, our study indicates that the Earth could run out of lithium as early as within 51 years if all existing fossil fuel powered passenger cars are replaced by EVs. Keywords: Sustainability; Lithium ion batteries; Electric vehicles; Lithium reserve Abbreviations: EVs: Electric Vehicles; LIB: Lithium Ion Batteries Introduction Several public policies are being implemented around the world [ 1 , 2 ] to promote Electric Vehicles (EVs) in order to tackle the problems of ...

Juniper Publishers- Journal of Robotics Abstract This article presents the most recent contributions to the field of agricultural robotics, with a focus on robot sprayers. The objective is to demonstrate the latest developments, specifically on robot sprayer systems for precision spraying (e.g. for weed control). The summary of the review shows that feasibility has been demonstrated in a number of projects with significant results especially in pesticide use reduction, with good spraying coverage for this complex agricultural task Keywords: Agriculture; Robotics and automation; Precision spraying; Human-robot interaction Introduction One of the most frequent and important task in agriculture is the application of fungicides, herbicides and insecticides.It is frequent because diseases are a common occurrence on plants which affect the plant production, and it is important because it can have a significant impac...

Juniper Publishers- Journal of Robotics Abstract Object manipulation is the most significant and challenging way for a robot to interact with its environment. It often requires computation on different channels of sensory information and the use of sophisticated controllers that can quickly lead to intractable solutions. In recent years, increasingly uncertain work spaces have lead researchers to turn to Partially Observable Markov Processes for robotic manipulation. The frame works provide methods to find an optimal sequence of actions to follow based on state belief and a partially observed world. This paper reviews the use of POMDP in the literature and points to fundamental papers on the subject. Keywords: POMDP; Robotic manipulation Abbreviations: POMDP: Partially Observable Markov Decision Process; RL: Reinforcement Learning Introduction Robots are increasingly expected to be more than mindless tools that are prog...

Juniper Publishers-Journal of Robotics Abstract Proposing new mutation strategies and adjusting control parameters to improve the optimization performance of differential evolution (DE) are considered a vital research study. Therefore, in this paper, a short review of the most significant contributions on parameter adaptation and developed mutation strategies is presented. Keywords: Evolutionary computation; Global optimization; Differential evolution; Mutation strategy; Adaptive parameter control Abbreviations: DE: Differential Evolution; EAs: Evolutionary Algorithms; CR: Crossover Rate; SF: Scaling Factor; FADE: Fuzzy Adaptive Differential Evolution; SDE: Self Adaptive Differential Evolution Introduction Differential Evolution (DE), proposed by Storn and Price [ 1 , 2 ] is a stochastic population-based search method. It exhibits excellent capability in solving a wide range of optimization problems with di...

Juniper Publishers- Journal of Robotics Abstract This research proposes a people-following mobile robot system that is equipped with Kinect RGB-D camera and a laser scanner, in which the Kinect’s skeleton tracking function helps, identify people in the depth image. First, the system selects a person who raises his two hands as the target to follow. Second, the system identifies the target to follow from the person’s location and color characteristics of clothes. When an occlusion occurs, the system uses the information from the laser scanner to guide the motion of the mobile robot and tries to re-recognize the target to follow at the same time. The people-following mobile robot accomplishes a human detection and follows only the target even if more than two people are located around the target person. The research conducts several experiments and shows the effectiveness of the proposed system to identify and follow a human in an indoor environment. Keywords: ...
