It started with a clean map and a warm feeling about math. Vector fields promised smooth paths, no nasty corners, elegant flow around obstacles. My ro...
Vector field navigation — it's the backbone of everything from warehouse robots to autonomous lawnmowers. But there's a knob everyone touches and few ...
You've seen it happen. A robot glides smoothly through open space, then hits a wall—and suddenly its behavior turns erratic. The navigation field coll...
You're running a simulation or a path-planning algorithm, and the vector field looks clean—until you zoom in. There it's: a tiny swirl that shouldn't ...
You've seen it happen. A robot that should glide smoothly instead circles a phantom point—a false attractor born from bad waypoint density. I've debug...
You've built a vector field navigation agent. It's supposed to follow gradients to a goal. But sometimes it just… stops. Or wanders in circles. Or osc...
You drop a robot in a room full of chairs, boxes, and a moving person. You want it to reach the far door without bumping into anything. The classic so...
Imagine you are programming a drone to map pollution in a coastal bay. Your vector field model says that a strong source sits near the river mouth—wat...
Your agent is stuck. Again. The vector floor looks fine in simulation — smooth gradients, no saddle points visible. But on real hardware, the agent or...
Vector fields show wind, water, or magnetic flow. But the grid you pick can invent patterns that aren't there. False convergence—where arrows seem to ...
It started with a forklift stopping dead at a seam. The left half of its local costmap said 'free'; the right half said 'occupied'. The robot sat ther...
You deploy your robot, watch it glide smoothly for a few second, then—nothing. It sits there, wheels twitching, trapped in a phantom well that does no...
Imagine your robot coasts smoothly toward a waypoint — then jerks sideways for no obvious reason. No obstacle. No sensor glitch. The path planner says...
Vector field navigation promises smooth, continuous trajectories. But when alignment drifts, your model doesn't just wobble—it breaks. I've seen teams...
