2. Background Vrobotics is dedicated to the development of robotic technologies aimed at assisting people with interacting with their environment. Our first robotic manipulator, V, is designed to work through voice and visual cues to perform basic functions given by the user. Ultimately, V will be able to replace larger tasks such as cleaning your kitchen and even cooking your food! http://www.2dayblog.com/images/2012/may/550x-robot-arm-mind-control.jpg Vrobotics

3. V Voice Recognition – Processing audio input into strings that can be used as input for the robotic arm and its subsystems. Control Systems – The kinematic modelling and algorithms that allow the arm to perform its required motion efficiently and effectively. Image processing – Processing video input into tangible object characteristics and spatial information Sensor Integration – Transforming raw data streams into real-world information about V’s actions and its surroundings. Electronics and Mechanical Systems – Developing of efficient and effectively hardware capable of performing the tasks requested by the user in a timely manner. V Systems Overview
