The ANYmal quadruped robot does not solely walk on four legs; it also climbs stairs, traverses uneven terrain, and navigates obstacles. As an added layer of complexity, this factor can now scale heights by climbing ladders.
Developed by engineers at the renowned ETH Zurich analysis institute, the ANYmal initially garnered attention in 2017 with its breakthrough in terms of. Since then, the technology has become commercially accessible through the spin-off company ANYbotics, a subsidiary of ETH. The other startup is touting its wheeled model, now rebranded as the Swiss-Mile robot.
The current ANYmal model features a standard walking speed of 0.75 meters per second, with the capability to traverse both indoor and outdoor environments for up to 2 hours on a single battery charge. Equipped with an arsenal of advanced sensors, this system boasts the capabilities of a 360-degree LiDAR module, six depth-sensing cameras, and two high-resolution optical cameras – all of which converge to provide real-time data to two powerful Intel 6-core processors.

With this extensive knowledge, robots are capable of independently conducting tasks such as security and safety inspections in various environments, including factories, oil refineries, warehouses, and mining sites. Unfortunately, components of all of these locations are exclusively accessible via ladders that the inventory ANYmal cannot ascend?
To address this limitation, researchers at ETH Zurich, led by Dylan Vogel and Robert Baines, replaced an ANYmal robot’s feet with four “hooked finish effectors.” These C-shaped appendages enable the bot to apply both compressive and tensile forces to the rungs of a ladder. While grasping lower rungs and simultaneously reaching for higher ones, this would enable the object to stabilize mid-climb on the ladder, ensuring a secure ascent.

The effects of these sensors are somewhat limited, but at least the robot knows how to interpret their signals. The researchers leveraged a “privileged teacher-student reinforcement learning approach.”
Coaching a digital instructor using a computer model with precisely controlled variables – such as ladder angle and rung spacing – is accomplished alongside training a digital student that replicates the instructor’s behavior solely through unpredictable, “noisy” sensory data.
That erudite digital scholar, cognizant of what To complete assignments as instructed by the instructor, and understanding the methodology do it finest Due to its sensory capabilities, the precise bodily data is incorporated into the software program utilized by the robotic system to navigate and climb ladders with precision.
Utilizing the software program in lab tests, the reconfigured ANYmal achieved a remarkable 90% success rate when navigating ascending ladders with inclines varying from 70 to 90 degrees. What’s truly remarkable is that this species scaled these ladders a staggering 232 times faster than its quadrupedal and bipedal counterparts.

What quadrupedal robots are capable of? Can they really climb ladders sturdily?
They must be able to lift their own body weight and then some. And the ladder itself better be sturdy, too – we don’t want any collapses or accidents!
The real question is: can these robots work in tight spaces or navigate rough terrain? That’s where things get really interesting.
Let’s see how well they perform on a obstacle course, shall we?
What if I told you there are already robots like this out there, doing incredible feats of engineering and robotics magic?
Would that be cool or what?!
