Abstract:
This paper presents the design and development of a new low-cost pick and place anthropomorphic robotic arm for the disabled and humanoid applications. Anthropomorphic robotic arms are weapons similar in scale, appearance, and functionality to humans, and functionality. The developed robotic arm was simple, lightweight, and has four degrees of freedom (DOF) at the hand, shoulder, and elbow joints. The measurement of the link was made close to the length of the human arm. The anthropomorphic robotic arm was actuated by four DC servo motors and controlled using an Arduino UNO microcontroller board. The voice recognition unit drove the command input for the targeted object. The forward and inverse kinematics of the proposed new robotic arm has been analysed and used to program the low cost anthropomorphic robotic arm prototype to reach the desired position in the pick and place operation. This paper’s contribution is in developing the low cost, light, and straightforward weight anthropomorphic arm that can be easily attached to other applications such as a wheelchair and the kinematic study of the specific robot. The low-cost robotic arm’s capability has been tested, and the experimental results show that it can perform basic pick place tasks for the disabled and humanoid applications.Keywords:

This study presents the model, design, and construction of the Arduino based robotic arm, which functions across a distance as it is controlled through a mobile application. A six degree of freedom robotic arm has been designed and implemented for the purpose of this research. The design controlled by the Arduino platform receives orders from the user’s mobile application through wireless controlling signals, that is Bluetooth. The arm is made up of five rotary joints and an end effector, where rotary motion is provided by the servomotor. Each link has been first designed using Solid Works and then printed by 3D printer. The assembly of the parts of the robot and the motor’s mechanical shapes produce the final prototype of the arm. The Arduino has been programmed to provide rotation to each corresponding servo motor to the sliders in the designed mobile application for usage from distance.

In contrast to Direct Current (DC) motors, the DC servo motor angular position can be controlled at a particular angle by utilizing a control signal. Arduino has as of late been utilized in a wide scope of control approach, particularly including closed loop system with servomotor because of its adaptability and simplicity. So as to control the DC servo motor, there are three distinct techniques that can be utilized by utilizing Arduino to be specific Arduino Integrated Drive Electronics (IDE), Support focus for Simulink (Support Package) and Arduino Input/yield (IO) Package. This paper presents a similar report on the servo motor position control (with voltage feedback) by utilizing the above strategies to discover the best strategy to control the complex servo motor system with closed-loop position input.

Abstract NOTE: The first page of text has been automatically extracted and included below in lieu of an abstract A LABVIEW-BASED ON-LINE ROBOTIC ARM FOR STUDENTS’ LABORATORY Abstract In this paper, the development of robotic arm experiments using the i-Lab Interactive Architecture is presented. Communication with the arm is done by using the RS-232 protocol. The robotic arm used in the laboratory has five degrees of freedom, each degree of freedom being controlled by a servomotor. The servomotors are controlled via pulse-width modulation (PWM), the width of each pulse being indicative of the position to which motor should move. Three experiments are considered. The first experiment simply makes the robotic arm available to the student for direct control by moving different sliders. Each slider controls a motor. This would be the preliminary task to students who are new to robotics, and would familiarise them with the workings of the robotic arm. The second experiment demonstrates the effect of gravity on a robotic arm at different data rates. The third experiment developed entails requiring students to program the positions of each of the motors for each sequence stage of robot movements. Students would draw up this movement to perform an instructor- determined task. The instructor would require the students to, for example, pick an object from one location and place the object in another location. The RA-01 robotic arm made by Images SI Inc. is used for these experiments and LabVIEW is used to create the laboratory clients and experiment engines. A visual feedback from the lab to the client is provided via a webcam. I. Introduction The field of robotics is largely unexplored by the underdeveloped and the developing countries. Few universities undergo course work in robotics and even fewer have labs for robotics. Yet, the field of robotics stands as one of the most promising of the future. The world is gearing up for the next level of automation where every device would be smart and able to do lots of things on their own without human input. The field of robotics holds front lines in these research areas with unmanned missions, explorations and excavations, home servant robots, robot playing sports and several other fields. With a dearth of robotics in the third world, the great brains in these parts of the world could be contributing more if only knew how to. This research work reported here was prompted by the lack of laboratories and lectures in the field of robotics in the authors’ environment. This research work aims to set up an online control engineering experimentation platform in the field of robotics. The aim was and is to expand the set of online experiments in the Control Engineering field while introducing newbies to robotics. The set of online experiments which this research work would put up are based on a robotic arm. Three experiments have been set up at the Obafemi Awolowo University by this research effort. The experiments are: 1. A simple slider control experiment 2. An effect of gravity experiment 3. A trajectory planning experiment

A cloud computing (CC) and Internet of things (IoT) became deeply associated with technologies of the internet of future with one supply the other a way helping it for the successful. Arduino microcontroller is used to design robotic arm to pick and place the objects by the web page commands that can be used in many industrials. It can pick and place an object from source to destination and drive the screws in into its position safely. The robot arm is controlled using web page designed by (html) language which contain the dashboard that give the commands to move the servos in the desired angle to get the aimed direction accordingly. At the receiver end there are four servo motors which are made to be interfaced with the micro controller (Arduino) which is connected to the wireless network router. One of these is for the arm horizontally movement and two for arm knee, while the fourth is for catch tings or tight movement. Two ultra-sonic sensors are used for limiting the operation area of the robotic arm. Finally, Proteus program is used for the simulation the controlling of robot before the hardware installation
