In the aftermath of a disaster it is common to see Search and Rescue teams struggle to get to affected areas due to damage to existing lines of access and the lack of accurate maps that reflect the ground reality after disasters. In this paper we introduce a system that makes use of a network of drones where different types of drones are tasked for different applications like 3D mapping of the extent...
This paper presents a review on mobile robot localization techniques that use infrared lights as artificial reference objects. Dead reckoning provides only approximate robot position estimation but the uncertainty in robot position increases with time due to inaccuracies in robot configuration and motion. A best state estimator algorithm is presented that combines robot odometry and infrared light...
In this paper design of Exoskeleton robot depending on human anthropometry has been discussed. Shoulder joint contributes most of the work space, kinematic model of shoulder joint has been discussed. Further the challenge lies with mapping this 7 DOF arm exoskeleton to a 6 DOF industrial robot. This has been addressed using the virtual KUKA model. Validation is done and same has been shown using C#...
Quadriplegic and non-verbal individuals, people suffering from cerebral palsy, stroke, traumatic brain injury, Galilean-Barre Syndrome, etc. find it difficult to convey their intentions as their voluntary motions are limited. In most of the cases the eye movements are unaffected and thus, the solution of using the eyes has the potential to develop a robust communication support method. Most of the...
Six degree-of-freedom motion platforms are extensively used as vehicular and flight simulators. It is difficult to modify the design of a platform after installation if some issues such as improving the performance and smoothness of the platform are encountered. Hence, various issues encountered such as jerky motion on using different mock-ups and irregular response are difficult to be dealt without...
This paper is on free and open source software architecture (FOSS) for remote labs in order to address the affordability and scalability of robotic education technology for sustainable deployments. The proposed Raspberry Pi-Arduino-based model architecture ensures lower cost while allowing some scalability, interoperability, portability and interchangeability to the low-cost online laboratory. Remotely...
The purpose of this paper is to present the model of a Humanoid robot inspired by Poppy, modified for heavier load capacity and the balancing of humanoid in multiple work environments. The design has been modified in order to use MX-64 servos with more torque capacity than MX-28 servos which were used in original design. We have also redesigned the ankle joint and feet to make it a more accurate human...
Many child deaths are reported in the past due to bore well accidents. During bore well accident an immediate rescue operation is required and it is quiet challenging to perform a rescue operation as the environment inside the bore well is highly unpredictable. Developing low cost robotic system and simple control will help rural people use it easily. In this paper, we propose a novel design of rescue...
Humanitarian challenges in developing nations such as low cost prosthesis for the physically challenged, have also led to substantial progress in robotics. In this paper, we implemented and deployed a low-cost remotely controlled robotic articulator, as an education tool for university students and teachers. This tool is freely available online and is being employed to generate robotic datasets for...
In this paper we present the design and development of a hand-motion recognition system as an interface between human and mechatronic systems such as UAVs and other rescue robots. The interface device, named as ARMatron, will be capable of identifying the gestures made by the user and convert them to suitable signals to activate the target gadgets. Suitable sensors on the ARMatron will sense the linear...
Hevea brasiliensis/Rubber tree is considered to be the most predominant plantation crop in Kerala which was found to be the major source of income for the 11.5 lakh planters within Kerala. Due to the availability of natural rubber from foreign countries at cheaper price, the current market price as well as the demand of Indian rubber is decreasing. Unfortunately in addition to low income from rubber,...
Educating children with autism is becoming a highly challenging task due to the nature of the disorder and limited interest of these children in interacting with people. Nevertheless, it is observed that most of the children with autism are good observers. This paper put forward and evaluates a novel teaching technique, Adapted Model-Rival Method (AMRM and a parrot-inspired robot for children with...
Robot hands with lower degree of freedom are used to reproduce the gesture of our hand, there are many gestures of our hand which cannot be reproduced in these hands. In this paper, we propose a design of anthropomorphic robot hand using twenty servo motor for twenty degree of freedoms which we can reproduce the exact and every gesture of our hand so that it is suitable for dexterous task like surgery...
Robotic rehabilitation has a significant potential to reduce the clinical labor costs of physiotherapy. Robotic therapy allows patients to have more in-depth repetitive movements while the therapists evaluate the progress of the recovery. This paper investigates the potential of a 6 degrees of freedom parallel robot, designed and built at the University of Birmingham, for use in robotic rehabilitation...
This paper presents a detailed review on humanoid robotic neck mechanism using a parallel manipulator. As the human neck is central to head and torso, the neck dictates the position and movement of the head. Mimicking the movement of a human head can be achieved in the robot by using parallel manipulators. In general, the parallel manipulators are referred as the Stewart Platform. As the neck in the...
