Robust adaptive projection-based control of a constrained quadrotor with two manipulators

Mohammad Mohammadi; Reza Dehghani; Ali Reza Ahmadi

Volume 11, Issue 2 , March 2022, , Pages 351-364


  In this paper, a quadrotor with two manipulators constrained on a straight path is modeled and a robust adaptive controller is proposed for it. Adding two manipulators to quadrotor increases its capabilities and applications in industry. Here, these two manipulators are used to place the robot on a constraint ...  Read More

Grasp analysis of a four-fingered robotic hand based on Matlab simmechanics

Eram Neha; Mohd. Suhaib; Shruti Asthana; Sudipto Mukherjee

Volume 9, Issue 2 , February 2020, , Pages 169-182


  The structure of the human hand is a complex design comprising of various bones, joints, tendons, and muscles functioning together in order to produce the desired motion. It becomes a challenging task to develop a robotic hand replicating the capabilities of the human hand. In this paper, the analysis ...  Read More

Fuzzy motion control for wheeled mobile robots in real-time

Mohammad Falsafi; Khalil Alipour; Bahram Tarvirdizadeh

Volume 8, Issue 2 , February 2019, , Pages 133-144


  Due to various advantages of Wheeled Mobile Robots (WMRs), many researchers have focused to solve their challenges. The automatic motion control of such robots is an attractive problem and is one of the issues which should carefully be examined. In the current paper, the trajectory tracking problem of ...  Read More

Dynamical formation control of wheeled mobile robots based on fuzzy logic

k. Alipour; m. Ghiasvand; B. Tarvirdizadeh

Volume 6, Issue 2 , June 2017, , Pages 79-91


  In this paper, the important formation control problem of nonholonomic wheeled mobile robots is investigated via a leader-follower strategy. To this end, the dynamics model of the considered wheeled mobile robot is derived using Lagrange equations of motion. Then, using ADAMS multi-body simulation software, ...  Read More

Improvement of position measurement for 6R robot using magnetic encoder AS5045

M. H. Ghasemi; A. H. Korayem; S. R. Nekoo; M. H. Korayem

Volume 6, Issue 1 , December 2016, , Pages 11-20


  Recording the variation of joint angles as a feedback to the control unit is frequent in articulated arms. In this paper, magnetic sensor AS5045, which is a contactless encoder, is employed to measure joint angles of 6R robot and the performance of that is examined. The sensor has a low volume, two digital ...  Read More

Coordinate influence on singularity of a 3-ups parallel manipulator
Volume 1, Issue 1 , December 2011, , Pages 53-58


  This paper shows the coordinates influence on singularity of a three degree-of-freedom structure, namely, three-Universal-Prismatic-Spherical (3-UPS) parallel manipulator. Rotational coordinates, which are chosen to define the orientation of the platform, affect the singularity of the manipulator. Euler ...  Read More
