"Welcome to an introduction to rotational motion and kinematics! In this video, we’ll break down the key concepts of rotational motion, including angular displacement, velocity, and acceleration.

In the latest twist in human evolution, scientists have discovered that a mysterious foot found in Ethiopia belonged to a previously unknown ancient relative. Dated to around 3.4 million years ago, ...

In this video, we introduce the fundamentals of kinematics in 2D, focusing on projectile motion. Learn how to break down the horizontal and vertical components of motion, apply key equations, and ...

So, you’re driving a car at half the speed of light. (Both hands on the wheel, please.) You turn on the headlights. How fast would you see this light traveling? What about a person standing by the ...

for chain in self._kinematic_tree: R = root_quat for j in range(len(chain) - 1): # (batch, 3) u = self._raw_offset_np[chain[j+1]][np.newaxis,...].repeat(len(joints ...

A kinematic model is a mathematical representation of a robot’s motion that focuses on the geometric relationships between elements and ignores external forces that affect motion. Kinematic models are ...

Abstract: The positioning deficiency of industrial robots is always caused by inherent kinematic errors, such as machining and assembly errors as well as the deformation and wear in the presence of ...

(Nanowerk News) The future storage and processing of data stand to benefit greatly from tiny magnetic whirlpools known as skyrmions, which are robust against noise and may be useful in lower power ...

Earth, sun, moon: three objects in space whose interactions have a pretty big impact on our lives. Earth orbits the sun once a year, and it rotates on its axis about once a day (depending on your ...
