M20 Series
There are wheels at the end of every leg. Flat ground goes by on wheels; stairs and steps are taken on legs. The body is symmetrical front to back, so it backs straight out of a 50 cm corridor without turning around. Two LiDARs and two wide-angle cameras come as standard, and batteries swap without cutting power.
The speed of wheels, the reach of legs.
Four things every M20 Series platform shares.
Two ways to move
Wheels on the flat, legs on stairs, steps and slopes. Up to 45°, with 25–30 cm continuous stairs.
Out without turning
Symmetrical front to back — it reverses straight out of a 50 cm corridor.
No shift change
Two batteries, swapped without cutting power. 3 hours and 15 km unloaded.
The same view either way
Two LiDARs and two 168° wide-angle cameras, front and rear. Both directions see the same.
Same chassis. Different compute, different muscle.
All three share the same dimensions and leg structure. The choice is whether it patrols by itself, how much it has to carry, and how cold the site gets.

The 5.0 / 9.0 m/s top speeds are manufacturer extreme-test data; products ship limited to 3.0 m/s. IP66 and IP67 hold only with both batteries fitted and do not cover submersion. The M20S upper figures of 5 h · 20 km require the extended battery, and the -30 to -20°C range requires the wide-temperature battery. Front and rear obstacle avoidance is planned for a later update.
Let's draw the route first.
Tell us the patrol path, the stairs on it, and the weight it has to carry — we will start by working out which model fits.
