How to minimize and synchronize travel time with velocity and acceleration constraints

I have the following simplyfied problem and have to develop an algorithm to optimize it. Let's imagine n number of trains with zero mass. Each train is placed on their own railway. Each train has it's owm maximum acceleration constraint. Each train…

Modeling a robotic arm in Python with acceleration/deceleration

I'm trying to model the motion of a robotic arm in Python. I want it to start from an initial position of 0 degrees and initial velocity of 0 deg/sec. It has a constant acceleration of 0.5 deg/sec**2 and a max velocity of 3 deg/sec. For now I am…

What's the difference between H265, x265, x264, H264 and which of these uses GPU instead of CPU and how to use H265 GPU NVIDIA acceleration in ffmpeg?

I'm not sure if x264/5 use CPU and if h264/5 use GPU and also if h265 is basically HEVC_NVENC for NVIDIA GPU acceleration. So, if you could give me more info about these encoding types it would be great. I understood that, summing up a lot, x26* use…

Given heading, pitch, bank of point A on a plane and an offset to point B, how do I calculate the heading, pitch, bank of point B on the same plane?

I have the heading, pitch, and bank from a sensor in the center of an entity (point A), and I want to be able to calculate the heading, pitch, and bank of another point of the entity (point B). If I know the offset from point A to point B, how do I…

Calculate acceleration from data points

I have a servo motor, and this servo motor I would like to make it follow a "motion pattern" as closely as possible, and use the same value for acceleration and deceleration. The attach picture illustrates the "motion pattern" (Y = velocity, X =…
