A novel spherical wheel driven by Omni wheels

2008 International Conference on Machine Learning and Cybernetics, 2008
A novel combination of Omni wheel and spherical wheel unit (CWWU) is presented in this paper, and its operating principle is basically a spherical wheel driven by two perpendicular pairs of Omni wheels. Thus, a CWWU base robot can perform the static and dynamic balancing function that a single wheel with inverse mouse-ball drive developed by Carnegie ...

A novel spherical wheel driven by chains with guiding wheels

2009 International Conference on Machine Learning and Cybernetics, 2009
A novel combination of chains with guiding wheel and spherical wheel unit (CWWU1) is presented in this paper, and its operating principle is basically a spherical wheel driven by two perpendicular pairs of chains with a set of guiding wheels. Thus, a CWWU1 base robot similar to the previous CWWU (combination of Omni wheel and spherical wheel unit) can ...

Modeling of a spherical robot driven by Omni wheels

2011 International Conference on Machine Learning and Cybernetics, 2011
This paper mainly derives the model of the invented spherical robot using Omni wheels to drive a spherical wheel. The dynamical model is derived based on Euler Lagrange approach. The general form of the robot is also presented. It is noted that the control input of the attitude of robot body originally is the torque exerted by two pairs of Omni wheels ...

A stabilization control of two wheels driven wheelchair

2009 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2009
The paper describes a stabilization control of two wheels driven wheelchair based on pitch angle disturbance observer (PADO). PADO makes it possible to stabilize the wheelchair motion and remove casters. This brings a sophisticated mobility of wheelchair because the casters are obstacle to realize step passage motion and so on.
