How to move the points of a sampled curve down onto a mesh below, using a Geometry Nodes graph in Blender. In other words, drape wet spaghetti onto the ground; drop points down. Update: Better (simpler, fewer nodes) solution is shown in the accepted answer here: blender.stackexchange.com/a/323267/98738 General solution shows an approach that allows both the curve and the terrain to have arbitra...

Even noisy data from AprilTag localization can be used to heavily improve robot odometry over just tracking the velocity of the robot's wheels. In this case the previous position estimate is first improved by moving it 70% of the way to the latest velocity-based prediction of the robot's location, and then the estimate is further improved by moving it either 10% or 50% of the way towards each A...

How to calculate the locations of control points in a cubic Bézier segment to best approximate a circular segment. You can play with this calculator online at www.geogebra.org/calculator/hkhhskxf This video also shows how to draw a cubic Bézier in Geogebra.

Given a robotic platform that rotates about an offset origin and the desire to fire a projectile along the surface of that platform at a target with a known height and distance away, how do we calculate the rotation angle of the platform? Video capture from www.geogebra.org/calculator/hztknweq

An endzone-huck to Sam "Parm" Williams is knocked down by Connor Stricklan, but Sam goes to the turf to catch it off the wall. Early points of the final game in the GRU 2023 Fall Open Indoor league tournament.

A point in the middle of the first half of the final game in the 2023 GRU Fall Indoor tournament. Unlike our pickup games, where the "end zone" is just the painted key, this league used the full width of the field up to the top of the key as the end zone. The white team went on to win by a single point in the final 2 seconds of the game.

Any planar circle viewed by a perspective 3D camera can be represented as a 2D ellipse on the screen. For any convex 2D quad ABCD representing the projection of the bounding square for the circle onto the screen, the tangent points G,H,J,K can be determined, which in turn can be used to find the center of the ellipse, P. The center point and any three of the tangent points define the ellipse. m...

Using Colorado Time Systems WTTC-1 Tabletop Controller to set the default period length for a game of Indoor Ultimate Frisbee. We set the time to 19:30 because our time slots are 20 minutes long, and it takes time to write down the score and perform these actions.

Regenerative braking is great for charging the battery on a downhill, but in my truck, on my commute, it gets “overwhelmed” 54 seconds into the ~600’ descent over one mile. There are separate messages the truck can produce for “Regenerative braking is limited due to high battery charge” (experienced at 72% charge) and “Acceleration and regenerative braking are reduced until the battery warms up...
