We're not done with point clouds

The sheer breadth of robotics problems

"Posts like these really highlight how much there to think about in robotics. Below the surface of what immediately comes to mind there is just an abundance of topics to address to get an actually well working robot." – fisian
Real‑world robots turn into a painful distributed system of cables, batteries, etc.

"And when you get to an actual robot, you find it’s a distributed system with all the attendant challenges, so you build yourself up for that, and then your time, attention, and maybe your soul are crushed by connectors, cables and batteries." – robotresearcher
Debate over collision checking—moving beyond noisy point clouds to sparser, predefined models

"Why don’t they marry the visual categorisation of objects with a sparse predefined model to simplify? Point clouds seem like a noisy layer to use and better as verification." – ilikerashers
