![]() Robotics has become an interesting area of research in the field of Electrical Engineering. However, the achieved recognition rate of gestures and postures should be improved in future, keeping the compromise with the system response time. The results show that the system allows the control of an industrial robot in an intuitive way. The orientation of the control unit is tracked and displayed using MATLAB. Finally, this prototype of the arm may be expected to overcome the problem such as placing or picking hazardous objects or non-hazardous objects that are far away from the user. The development of this arm is based on LPC2148 and ATmega328 along with a personal computer for signal processing, which will all be interfaced with robotic arm using serial communication and with transmitter using wireless. For proper control mechanism and to reduce the amount of noise coming in from the sensors, proper averaging algorithm is used for smoothening the output of the accelerometer. Here it is propose to build a robotic arm controlled by natural human arm movements whose data is acquired through the use of accelerometers. In today's world there is an increasing need to create artificial arms for different inhuman situations where human interaction is difficult or impossible. The testing was carried out on a Jominy End Quench Apparatus and it was observed that the robot was working appropriately. Arduino is used for controlling the robotic arm. Joints are moved using DC servo motors and the end effector is positioned using a pneumatic cylinder which is actuated using a solenoid valve with flow control valve to adjust the stroke speed. Actual robotic arm has been designed using INVENTOR modelling software. With this approach it is possible to develop algorithms for controlling movements. In the present paper, kinematic homogenous 4X4 matrix calculation is used to control the 3-axes modular robotic arm. Khosla developed a system which combines the flexibility of reconfigurable modular hardware with modular programming tools, allowing the users to rapidly create a manipulator which is custom-tailored for a given task. K.H.Wurst developed the first Reconfigurable modular robots in the context of manipulator arms. ![]() ![]() The flexibility and control of a robotic arm has been a challenge since earlier days of robots. ![]()
