3DOF Multitouch Haptic Interface with Movable Touchscreen

2017
This paper reports on the development of a multitouch haptic interface equipped with a movable touchscreen. When the relative position of two of a user’s fingertips is fixed on a touchscreen, the fingers can be considered a hand-shaped rigid object.

3DOF tracking accuracy improvement for outdoor Augmented Reality

2010 IEEE International Symposium on Mixed and Augmented Reality, 2010
Outdoor Augmented Reality (AR) gained popularity recently due to its potential for location based mobile services. However, most commercially available Global Positioning Systems (GPS), except for the expensive high-end models, do not provide accurate location information that is enough to be used for displaying practically meaningful location based ...

3DOF drawing robot using LEGO-NXT

2011 15th IEEE International Conference on Intelligent Engineering Systems, 2011
This paper presents a 3 DOF robotic arm used for drawing on a paper sheet. The robotic arm is constructed using LEGO NXT bricks. The purpose of the development was to create a control system of the servo motors for the robot, as well as the inverse kinematics, used for moving the arm. The NXT controller is running LejOS for optimal motor control, while

Force capability in general 3DoF planar mechanisms

Mechanism and Machine Theory, 2015
Abstract This paper presents a mathematical closed-form solution to obtain the maximum force with a prescribed moment in robotic mechanisms with 3 degrees of freedom. The proposed mathematical model is obtained using classical optimization methods, screw theory and the Davies method as primary mathematical tools. The novelty of this study lies in the

3DOF High Resolution Inertial Piezoelectric Motor

2019 IEEE International Ultrasonics Symposium (IUS), 2019
Development of multi degree-of-freedom (DOF) high-resolution motors is becoming of increased importance for nanotechnology, micro-robotics, and laser technology. A novel design of 3DOF rotary type piezoelectric motor is proposed. It includes three novel 2DOF inertial piezoelectric actuators, housing, and hemispherical rotor. 2DOF actuator consists of a

Discrete Dual–Heuristic Programming in 3DOF Manipulator Control

2010
In this paper we propose a discrete tracking control system for 3 degrees of freedom (DOF) robotic manipulator control. The control system is composed of Adaptive Critic Design (ACD), a PD controller and a supervisory term derived from the Lyapunov stability theory.
