Dynamic Obstacle Avoidance Algorithm for Autonomous Mobile Robots

Noor Abdul Khaleq Zghair; Ahmed S. Al-Araji

Volume 23, Issue 2 , June 2023, , Page 63-82


  A mobile robot's major purpose is to get to its destination by traveling over an optimum path defined by various parameters such as time, distance, and the robot's safety from any impediments in its path. As a result, the backbone of the autonomous mobile robot is path planning and obstacle avoidance. ...  Read More ...

Spectral And Energy Efficiency Analysis For Beamforming Optimization Objectives For Wireless Massive MIMO Systems

Zaid Hashim Jaber; Dheyaa Jasim Kadhim; Ahmed Sabah Al-Araji

Volume 23, Issue 1 , March 2023, , Page 10-22


  Massive Multiple-Input Multiple-Output (MIMO) is an extension of the conventional MIMO in the wireless systems which improves both of the access density and the spectral efficiency by adding a massive number of antenna array at the base station (BS). Massive MIMO increases the spectral efficiency by ...  Read More ...

Modified Tracking Differentiator for Enhancing the Performance of Exoskeleton Knee System Based on Active Disturbance Rejection Control

Nasir Ahmed Alawad; Amjad J Humaidi; Ahmed Sabah Alarejee

Volume 23, Issue 1 , March 2023, , Page 69-83


  Exoskeleton robots help users with mechanical forces by recognizing their intentions, and they require a lot of energy efficiency, a lot of load capacity, and a good fit. A basic one degree of freedom (DOF) construction was devised in this work, which was mostly used in the knees of exoskeleton robots. ...  Read More ...
