    Desenvolvimento de um sensor híbrido-inclinação + EMG, para aplicações em robótica e fisioterapia
    (Universidade Federal do Espírito Santo, 2011-03-17) Bôrtole, Magdo; Bastos Filho, Teodiano Freire; Vassallo, Raquel Frizera; Ferasoli Filho, Humberto
    Equipments used to capture EMG signals are usually expensive and difficult to use in environments outside laboratories. This paper describes the development of a hybrid sensor capable of capturing myoelectric and inclination signals, provided by a pair of differential electrodes and a three-axis accelerometer as sensor devices. The information captured by the hybrid sensor can be used for biomechanical analysis of human movement, and is transmitted via Bluetooth communication, leaving the sensor free of wires and cables. The hybrid sensor has applications both in Robotics as Physiotherapy. In Robotics it has been used as a standalone system for controlling a robotic wheelchair for disabled people, through the user's head movements, achieving good results. Also in Robotics, it was used to control a small robot with a gripper, in a project to assist children with severe physical disabilities. In the area of Physical Therapy it has many applications where the collection of EMG signals is required, and was used to detect tilting of body parts in Physiotherapy. In its final state, the hybrid sensor consists of a portable electronic device, wireless, small, lightweight, highly autonomous, with high calculation capacity and high rate of data transmission. These features allow its use outside laboratories, expanding the application area.

    Implementação de um quadrotor como plataforma de desenvolvimento para algoritmos de controle
    (Universidade Federal do Espírito Santo, 2010-06-30) Melo, Alexandre Secchin de; Salles, Evandro Ottoni Teatini; Côco, Klaus Fabian; Lima, Luis Eduardo Martins de; Orlandi, José Geraldo das Neves
    This work aims the implementation of a unmanned, four-rotor miniature flying machine as a development platform, part of a long term research. The final goal, yet to be achieved, is the realization of a flying object with maximum practicable degree of autonomous decisions based on the on-board sensory and computational power, control strategy and assigned task. Up to this work, it consists of a low cost electro-mechanical hardware, whose electronic part allows the implementation of an 8-bit microcontroller-based, MEMS accelerometer and gyroscopes, allows the implementation of a generic fly control for attitude stabilization. The broad spectrum of applications includes: the inspection of various kinds of environments such as electric power transmission lines, police surveillance of woods and hard-to-reach places with sky sight for fugitive detection, crops and herd monitoring, as well as film takings for the cinematographic and real estate industries. Tests undertaking so far with the prototype suggest the successful implementation of a fly attitude controller.
