Being Wheeled or Walking

Being right or being happy: pilot study

Wheeled Rob 17 . Wheeled Robots

The purpose of this chapter is to introduce, analyze, and compare the models of wheeled mobile robots (WMR) and to present several realizations and commonly encountered designs. The mobility of WMR is discussed on the basis of the kinematic constraints resulting from the pure rolling conditions at the contact points between the wheels and the ground. According to this discussion it is shown tha...

Walking the talk: Value importance, value enactment, and well-being

Prior research on intrinsic versus extrinsic values has focused on the comparative importance subjects assign to the two types of values, showing that relative intrinsic versus extrinsic value orientation (RIEVO) predicts higher or increased well-being. In two studies, we show that rated action taken regarding the two types of values is just as essential to study. Support was found for four hyp...

Kinesin: walking, crawling or sliding along?

Kinesins are microtubule-based motor proteins that are involved in cargo transport and mitosis. They are called "motors" because they convert chemical energy to mechanical energy (i.e. force and motion). They use the energy of ATP hydrolysis for their enzymatic processes by walking on microtubules. However, the mechanism underlying their motion has been unclear. Recently, conventional kinesin, ...
