One of my Bachelor’s project students this year has developped a cool online interactive demo for our (now somewhat older) trained PRIMAL model, where you can define grids of any size, add/remove obstacles, and add agents and goals freely, before seeing the results of PRIMAL planning reactive trajectories for all agents online in front of you. We will keep on improving this demo,. and likely add more models (e.g., PRIMAL2, SCRIMP, etc.), but please have a look and try it for yourself. Any feedback is of course very appreciated :-)
