Overviews, Studies (1)

I would like to start this new category by introducing two studies (two university projects with link to the reports) around the Wiimote and its capabilities. Indeed, this category will deal with all
interesting publications around the world and about an experiment use of the wiimote :

Summary	Robots are designed to help humans. Space robots are of particular importance as they aid or replace astronauts in difficult possibly dangerous extravehicular activities. However, robot intelligence and autonomy are still limited. Therefore, robots need to be supervised or directly teleoperated in order to accomplish complex tasks in diverse environments. The focus of this thesis is on wireless teleoperation of robotic manipulators. The literature review introduces the reader to space robotics and other relevant achievements and prospects. State-of-the-art techniques of teleoperation on Earth as well as in space are examined. A damped least squares algorithm was developed to solve the inverse inematics problem and avoid joint limits, thus enabling continuous teleoperation of simulated robot arms. The motion sensing capabilities of the Wii remote controller by Nintendo are analyzed with regard to the possible use as teleoperation interface device. Three different robot arms were simulated for this thesis and can be teleoperated using the Wii remote as input device. The robot arms comprise the Workpartner arms (TKK), a timber loader crane (Kesla) and the Lynx 6 robot arm (Lynxmotion). Three modes of teleoperation are implemented to give the operator a higher degree of control over the arm. The algorithm and the teleoperation modes have been demonstrated with the Lynx 6 robot arm and the Wii remote as input device.

Comment	Filippi also performed a great job with a Matlab interface for the motion sensors of the Wiimote. fWIIne is enough similar to his MEX command. The source files comes from the open source project Wiim.	Rate wwwww

Summary	This is a bachelor project at the Department of Computer Science at the University of Copenhagen (DIKU). In this report we describe how we have developed a class library – WiiLib – that enables communication with and processing of data from a Wii-controller. The Wii-controller is an input device for Nintendo’s recent console – Wii. Since Nintendo has designed the controller in a way that makes it possible for it to communicate with a PC through Bluetooth, there is a motive of curiousity behind experimenting with the controller connected to a PC. The project also includes an implementation of a WiiLib-based extension to 3DOT; a 3D-engine in development at DIKU. WiiLib makes it possible for an application to read estimates of the Wii-controller’s orientation and relative position. The estimates can be used to manipulate objects in a 3D environment and are calculated using several methods; among these an adaptive method which we have developed ourselves and described in the report. The result of the estimated orientation is satisfying usingWiiLib’s adaptive method, but loses precision when the controller is also exposed to non-rotational movement. The result of the estimated position, on the other hand, is not satisfying because it is heavily affected by noise and therefore only works under absolutely perfect conditions.
