There doesn’t seem to be many autonomous stair negotiating robots. I’ve googled around and not found much. Any links would be appreciated.
The packbot isn’t autonomous, it’s radio controlled. But is definitely the leading contender in high tech tracked rovers.
Asimo is autonomous.
Our platforms aren’t autonomous but many of them climb stairs with ease.

Irobot is working to add some autonomous features to their packbot. For my part, making the packbot autonomous is not complicated. Add a microcontroller and some sensors, bypass the remote control, wire the motors and send the command “full fast forward”. Then you have your autonomous robots able to climb stairs.
I think the big challenge in climbing stairs is much more mechanical than software. Except for humanoid like Asimo. This is not the same story.
Your platforms look really robust and professional. It will be interesting to see them in action.
