Learn the differences between motion profiles! 💨 A real demonstration of engineering skills. In each robotic arm, in each legged robot, you will discover actuators that make the robot move! Let's compare two motion profiles: rectangular and trapezoid. - A rectangular motion profile is like a car with abrupt...

You stopped too soon. You need a 4th order TG.

That’s exactly how I press on my brakes in my car so I don’t have the backward head jolts. I move forward in my seat when I brake, but do not shoot backward when fully stopped. Cool to see the ‘math’ of how I drive.

Show me an S-profile with minimised jerk

In Germany the🍺 demo is allowed only with jerk limited s-curve velocity profile:

bet there is some connection to window functions like the hanning window here

Great demo! Rectangular (aggressive) for sprint bots. Trapezoidal for liquids, cameras, and fragile end effectors.

nice! interesting question would be what's the acceleration a(t) such that the drink doesn't spill and it goes from one side to the other in a smallest amount of time

Was it really necessary to use beer? It goes bad, you know!

Nice explanation! Feels like Trapezoidal is some sort of Low pass filter equivalent in Electronic circuits.

Great breakdown of motion profiles! Smoothness vs. speed is key. Any favorite applications for each?

Oh huzzah. You showed impulse vs smoothed impulse response, and the effects of inertial dampening with fluid dynamics. *slow claps*

jerk on, jerk off

Excellent! RE: Trapezoidal Have you considered different approaches to the smoothing algo? Use regular low pass (can include overshoot), critically damped (ensures best time to target with no overshoot). For extra points, you can go "spring and damper" for these too.
