r/robots

I mean a robot that could cook for you, drive you somewhere, watch your kids, take care of an elderly parent, or even make decisions for you in an emergency.
At what point would you stop trusting it and want a human involved?

Turns out you don't need active adhesion (vacuum, electromagnets) for ceiling locomotion — passive permanent magnets in Quaddle open source robot's foot tips are enough, as long as the gait is designed for holding contact upside down instead of just an inverted version of the ground-walking gait.

The interesting part wasn't the magnets, it was the gait — same open source robotics platform OpenCat, same 4 servos, just a different motion profile. Planning to open source this gait's code before it ships too, so anyone curious can adapt it, not just read about it.

Anyone else working on non-standard locomotion modes (climbing, inverted, whatever) — what ended up being the hardest part for you?

DR02 humanoid tackles outdoor stairs, highlighting its dynamic mobility and rugged capabilities in challenging environments.

Deep Robotics has released new footage showing its DR02 humanoid robot climbing outdoor concrete stairs, highlighting the machine’s ability to handle challenging terrain and maintain dynamic movement.

Been testing how much mechanical diversity I can get out of Quaddle robot by changing the attachment instead of adding more actuators. Same 4 servos and the same OpenCat firmware the whole time — what changes is the attachment (3D-printed, mostly) and which gait is loaded for it:

- Biped: printed base clips on, switches to two-legged walking

- Tricycle: printed wheel mount + a bearing wheel, front legs go passive and drag

- Bar-spin: printed grippers clip onto a bar, full 360° rotation gait

- 4WD: wheel kit replaces all 4 legs, standard car driving

- Water-paddle: printed footpads, paddling gait (works, though we've sunk it twice)

This is pre-release — not in production yet, but I wanted to share this fun experiment since keeping the servo count fixed while switching locomotion modes was a fun constraint to design around. The gait codes and the 3D-printed parts will be open sourced.

Happy to go into Quaddle's gait/kinematics details in the comments if anyone's curious.

I just thought people might enjoy watching this. I am ready for servitors, honestly.

Chinese humanoid robot makers accounted for over 97% of global shipments in 1H26, as volumes more than tripled to 19,100 units.

Shanghai-based Agibot led with 44% of global shipments (8,400 units), overtaking Hangzhou-based Unitree Robotics.

Industrial and commercial sectors accounted for more than 70% of total deployments, a sharp rise from roughly 50% a year prior.

Annual shipments are projected to hit 60,000 units by the end of 2026
