I ran into this post on linkedin recently. I have personally expirienced some of these problems. I am posting this as a placeholder to write down my own thoughts.

1) The Long-Tail Problem in Robotics Is Unforgiving
2) LiDARs Aren’t as Robust as You Think
3) Localization: Easier Said Than Done
4) Scaling Smart: Fewer Clients, More Efficiency—Customization Is a Trap
5) Autonomy Is Just Step One—Integration Is What Matters
6) Running a Robotics Startup Feels Like Running Multiple Companies
7) Global Expansion in Robotics: The Early-Stage Trap
8) The Hardest Part? Building the Right Team
