What hundreds of daily tracking tests look like in one frame

Every day, we take Beni outside and test his tracking in real crowds. This is what hundreds of those sessions look like layered into a single frame.

Each skeleton is someone Beni locked onto and followed, no GPS, no wearables, purely visual. The colored trails trace the exact path each person took.

One target per run. Stack them all together and it starts to look like choreography. The inset shows what Beni actually sees from its POV.

Battery stress test: Beni on a treadmill until the battery died — 1h44m

We still get comments saying this is all CGI / fake / just marketing — so here's a raw stress test. No cuts, no tricks.

All terrain stress test for Beni

We are actively refining its adaptability right now. What kind of terrain or obstacle course should we throw Beni into next?

Tire options — which one are you picking?

Been testing different tires on Beni lately. Here's what we've got so far:

A) Smooth — quiet, rolls nice on flat ground
B) Textured — a bit of everything, decent grip
C) Chunky — full send on grass and gravel

Which vibe are you? And where are you planning to run yours? We will make the tires swappable, so tell us if you want more options!

Beni jumps over Beni!

Just wrapped up a testing session and decided to see what happens when you put two Benis together.

This is what happens when test team forgot to hit "record"

Tracking test in the skatepark today, and our dear test team forgot to hit record on Beni, so here's the screen recording from Beni's live preview and skatepark's security footage. It's a good jump anyways!

Home kick test — self-recovery from every angle

Quick home test. Kicked it from different directions to see how the self-recovery handles it. Gets back up every time:D

Stairs are hard — part 2

New hardware, outdoor steps this time. I push the stick forward, the robot detects the stairs and decides when to jump on its own.

First part is daytime, clears all 3 steps, off the top, landed upright. Second part is at night: first attempt doesn't make it up, second one clears it. Added the night footage to show the controller input. Just push forward, everything else is the RL policy: stair detection, jump timing, balance, recovery.

Big upgrade from last time where I was triggering every jump manually. Still working on making it more consistent.

durability test, 5m/s wall crash

We posted a 4m/s concrete wall test a few days ago with an older prototype. Bumped it up to 5m/s (~11 mph) on the newer one.
First clip is full speed, no slow-mo: hits the slab, tips over, gets back up on its own. Second clip is the slow-mo replay, same speed, but this time it doesn't go down.
Same philosophy: crash it on purpose, find what breaks, fix it. We're stress-testing the frame, the joints, and the self-recovery behavior all at once. Pretty happy that it can eat a 5m/s impact into concrete and either stay standing or pick itself back up without any help:)

durability test, concrete wall at 4m/s

Trying to build a robot that lives outdoors, need to find the failure modes early, so we run tests to have it run into things.

This is an older prototype,but the process is the same. Ran it into a concrete wall a few times at 4m/s(~9 mph) to see what holds and what doesn't. Every impact is a little different: sometimes it pops back up on its own (got lucky!), sometimes it just lies there. One run the battery flew out, turned out the latch wasn't strong enough for that kind of load. Fixed since. Crashes are data, and it's fun to watch it improve every day!

Took it to the park. Turns out playground bumps make a decent test track

Older prototype, but it's still good for outdoor locomotion testing. No terrain-specific tuning, just seeing how far we can push it before something breaks.
