Abstract: This study is dedicated to addressing the predefined-time attitude tracking control problem of spacecraft in the presence of actuator faults, unmeasurable angular velocity, system ...

Here’s a draft of my next column for the Notices of the American Mathematical Society. It’s about the inverse cube force law in classical mechanics. Newton’s Principia is famous for his investigations ...

scikit-kinematics primarily contains functions for working with 3D kinematics, e.g quaternions and rotation matrices. This includes utilities to read in data from the following IMU-sensors: - polulu - ...

Angular momentum is conserved microscopically. However, how conservation works even in simple reactions encountered in atomic, nuclear, and particle physics is not immediately obvious. We examine ...

Angular velocity is a measure of how quickly an object rotates around a specific axis or point. It plays a significant role in fields such as physics, engineering, and astronomy. Understanding and ...

Grab any physics textbook and you'll find formula after formula describing how things wobble, fly, swerve and stop. The formulas describe actions we can observe, but behind each could be sets of ...

We develop a theory for the dynamics of a magnon on top of a domain wall in a ferromagnetic nanotube. Due to the geometry of the sample, domain walls are classified by the Skyrmion charge which counts ...

Abstract: In this paper, we propose a geometric control law for attitude robust control problem of a rigid body system without angular velocity measurement. We suppose there is a disturbance related ...

In lots of problems in robotics and computer vision we need to be able to describe the position and orientation (aka its pose) of something relative to some coordinate frame. With robot arms we may ...
