2014 Journal Article S. Sanju, Nippun Kumaar A A, and Sudarshan, T. S. B., “Autonomous Robotic Arm With Enhanced Intelligence”, International Journal of Advanced Computational Engineering and Networking, vol. 2, pp. 12–17, 2014.[Abstract]

In robotics for accomplishing simple and complex tasks, manipulation is a very important aspect. For maximizing the robustness and minimizing the cost there is no ideal solution for manipulation. Service robot systems have long been a goal of robotics research. This proposed work deals with the design and development of an autonomous robotic arm with enhanced intelligence. Amrita Articulated Robotic Manipulator, AARM-II is designed and fabricated, and is used for the realization of the proposed algorithm. Servomotors are used as actuators. A computer through a serial port interface using Flash Magic terminal controls the arm. The arm will be capable of picking and placing the objects in the sequence given by the user through PC terminal; if the arm is ideal it enters into random pick and place mode. Object’s source and destination order is entered in the user interface application. The trajectory planning is done with the help of Inverse Kinematics (IK). Geometric approach is followed to obtain inverse kinematic solutions. The work also aims at addressing the user interrupts instantly while the robot is in random pick and place mode and arrange the object in the sequence provided by the user in an efficient manner. The Microcontroller used is ARM7 based Blueboard LPC2148.

2013 Journal Article Nippun Kumaar A A and T.S.B. Sudarshan, “Learning from demonstration with state based obstacle avoidance for mobile service robots”, Applied Mechanics and Materials, vol. 394, pp. 448-455, 2013.[Abstract]

<p>Learning from Demonstration (LfD) is a technique for teaching a system through demonstration. In areas like service robotics the robot should be user friendly in terms of coding, so LfD techniques will be of greater advantage in this domain. In this paper two novel approaches, counter based technique and encoder based technique is proposed for teaching a mobile service robot to navigate from one point to another with a novel state based obstacle avoidance technique. The main aim of the work is to develop an LfD Algorithm which is less complex in terms of hardware and software. Both the proposed methods along with obstacle avoidance have been implemented and tested using Player/Stage robotics simulator. © (2013) Trans Tech Publications, Switzerland.</p>

2014 Conference Paper Nippun Kumaar A A and Sudarshan, T. S. B., “Path Mapping and Planning with Partially known Paths using Hierarchical State Machine for Service Robot”, in 3rd International Conference on Robot Intelligence Technology and Application 2014 (RiTA), FIRA 2014, Beijing, China, 2014.[Abstract]

Path mapping is a very essential part of a mobile robot navigation system. In this work, a novel technique to map and plan path for a mobile service robot without any vision aids in indoor environment using hierarchical state machine with partially known paths is proposed. The known paths are taught to a robot using Learning by Demonstration technique (LfD). The first phase of the algorithm is to map the paths as a hierarchical state machine using the partially known paths. Second phase is to plan the path given the source and destination. The algorithm is implemented and tested using a 2D simulation environment platform, Player/Stage.

2011 Conference Paper Nippun Kumaar A A and Sudarshan, T. S. B., “Mobile Robot Programming By Demonstration”, in Emerging Trends in Engineering and Technology (ICETET), 2011 4th International Conference on, Port Louis, 2011, pp. 206-209.[Abstract]

Programming by demonstration is an End-user development technique for teaching a computer or a robot new behavior by demonstrating the task to transfer directly instead of programming it through machine commands. In this paper we propose two new techniques to obtain the control code for a mobile robot through "programming by demonstration". Initially, a robot is controlled by a human operator who manually guides the robot through a desired path this is called teaching phase, and then the robot will navigate autonomously with taught information this is called execution phase. In contrast to traditional robot programming techniques, these methods does not require specialized technical or programming skills, but translates demonstrated behavior immediately into executable code. This has obvious implications for the widespread use of personal service robots.

2012 Conference Proceedings Nippun Kumaar A A and Sudarshan, T. S. B., “Sensor Counter Approach for a Mobile Robot to Navigate a Path Using Programming by Demonstration”, Proceeding International Conference on Communication Technology and System Design 2011, Procedia Engineering, vol. 30. Elsevier, pp. 554–561, 2012.[Abstract]

This paper presents a sensor counter approach for a mobile robot to navigate a path using programming by demonstration. In this paper a hybrid method which uses sensor values and counter values as path variables has been proposed, in order to avoid the dynamic obstacle in the environment we propose an obstacle avoidance algorithm (OAA) which is merged with hybrid method. Proposed method has been implemented and tested in a mobile robot platform AAMoR-1. Experiments has been done in an real time test environment to find the accuracy of the robot, the robot has been taught a particular trajectory by a human operator and later changing the robot to autonomous mode where in it moves in the same trajectory as taught, obstacle avoidance algorithm has also been tested by adding an obstacle in the taught path. Good test results have been obtained.
