That occurs from a combination of the high compressive force and the angular motion
of the flight relative to the barrel wall during rotation.
It should be noted, however, that the coefficients of static friction were tested during linear motion and the free moments were measured during angular motion
. While the rubber-bottom boots and running shoes had similar coefficients of static friction, the running shoes may be more resistant to angular motion
The system describing the joint deployment is a combination of two systems: angular motion
and translational motion, the mathematical models of which are presented in [9,10].
The described method could be quite effective granted that there is a sufficiently sensitive angular motion
It provides similar performance to a hexapod, yet allows for a lower profile and longer XY travel ranges (with reduced angular motion
Romani, professor of physics at Stanford University and member of the research team, said in the statement: "If you imagine a snail on the recently-discovered Earth-like planet orbiting Proxima Centauri - 4.243 light-years away - moving at 1 cm a second, that's the angular motion
we're resolving here."
Accelerometer and gyroscope could provide linear and angular motion
In order to design the slip compensation scheme, the robot is operated in single wheel turn mode; a special form of differential drive mode in a two wheel drive mobile robots that has been used to estimate the turning efficiency and quantify the amount of wheel slip in angular motion
about the horizontal axis aligned with the swimming direction corresponds to 'roll'; motion about the vertical axis corresponds to 'yaw'; and rotation about the horizontal axis perpendicular to the swimming direction corresponds to 'pitch'.
Accelerometers detect linear motion and tilt angle, gyroscopes detect angular motion
, magnetometers detect magnetic fields, and combo sensors are a combination of all the sensors.
