Cost Effective Robotic System Using Arduino

Robotics these days is winding up progressively well known because of assorted applications. The framework executes Inverse Kinematics of a Robotic Arm and improves its working utilizing Artificial Intelligence, by methods for item following. It will accomplish the objective of picking and setting the ideal item. Continuous framework is utilized to accomplish complex equipment usefulness. The capacity to self-repeat is one of the unmistakable highlights of living life forms. Robots equipped self-replication would profoundly affect the field of apply autonomy by enhancing lifetime and vigor. The point of this diary is to wipe out the manual control for item arranging framework. Robot arm structure in this exploration utilizes two joints, three connections and servo engines to drive. Microcontroller is utilized to create required PWM motion for servo engines. In this exploration the position control of robot arm was planned by utilizing kinematic control techniques. Along these lines, kinematic strategies can clarify the investigative depiction of the geometry movement of the controller with reference to a robot facilitate framework settled to an edge, without thought of the powers or the minutes causing the developments. For arranging framework, Metal finder is utilized to identify the metal or non-metal. This position control of pick and place robot arm is completely tried and the outcome is gotten all the more exactly. In this modern condition taking care of with certain gear will require total exactness such sort of work are being finished by mechanical robots. We are proposing an adjusted technique for machine learning for the modern robots by utilizing Arduino UNO. And furthermore we are taking a shot at replicator display for further more straightforward plan and further by we are planning model that could clarify the working of proposed model as further of replicator.

A new method for position control of a 2-DOF robot arm using neuro–fuzzy controller

Robot manipulators have become increasingly important in the field of flexible automation. So modeling and control of robots in automation will be very important. But Robots, as complex systems, must detect and isolate faults with high probabilities while doing their tasks with humans or other robots with high precision and they should tolerate the fault with the controller.This paper introduces a Neuro-Fuzzy Controller (NFC) for position control of robot arm. A five layer neural network is used to adjust input and output parameters of membership function in a fuzzy logic controller. The hybrid learning algorithm is used for training this network. In this algorithm, the least square estimation method is applied for the tuning of linear output membership function parameters and the error backpropagation method is used to tune the nonlinear input membership function parameters. The simulation results show that NFC is better and more robust than the PID controller for robot trajectory control.

Effect of High-Stiffness Timing Belt for Oscillation Damping in Position Control of Robotic Arm

Timing belts are generally used in robotic arms. In servo systems, stiffness of the system is the most important property for its performance. In this paper, we describe a 1-DOF robotic arm which was designed with basis on a basal plate transfer robot. A purpose of this study is a comparison of a standard timing belt and a high-stiffness timing belt for oscillation damping. By using the high-stiffness belt, we can improve the performance of the oscillation damping. We conducted a torque feedback as a minor-loop of a position control in the next section. This method effectively reduced undesired vibrations with both the standard belt and the high-stiffness belt.

Angular position control of robot arm.

A robot arm with high speed response is desired, but the development of a rapid robot compels us to take the bending dynamics of the arm into consideration. That is, the plant is no longer a low order lumped parameter system. Although the order of the plant is never infinite, it must be rather high. In order to obtain a reasonable control law, it is necessary to use a reduced order model for the plant because the time to be spent for computing the control signal for each sampling instance is strictly limited. The pole assignment technique is employed to control the angular position in this paper. The placement of poles far away from the imaginary axis is desirable for obtaining a quick control system, but may result in spillover instability.
