Regular and reliable inspection of infrastructure is a key requirement for the safe and efficient operation of industrial sites. The four-legged robot ANYmal is designed to traverse complex terrain while carrying a substantial payload. With onboard sensors and computer vision algorithms, ANYmal autonomously performs visual, thermal, auditory, and geometrical inspection as well as gas-content detection. A detailed protocol of the inspection round allows the site operators to maintain safe working conditions efficiently.
Agriculture & Forestry
Fully ruggedized, water- and dust-proof and with a multi-hour battery capacity, ANYmal can move into remote and hard to reach places. For agriculture and forestry, an onboard laser sensor allows accurate surveying and mapping of the environment to measure and characterize plant growth. And thanks to its legged locomotion, ANYmal does not get stuck in undergrowth, rubble, sand, or snow.
Potential dangers or threats cannot be detected too early. Fully autonomously, ANYmal can patrol and monitor natural and human-made environments without getting tired. In case of an emergency, ANYmal can be remote-controlled from close and far distances to support first responders. Providing a live video and audio feed and a 3D map of the environment, risks can be assessed without putting people in harm's way.
Robotic Platform Capabilities
ANYmal’s legs provide unparalleled mobility in all directions when moving up and down stairs, climbing over obstacles, steps, and gaps, and crawling into tight spaces. On moderate and flat terrain, the legs provide high-speed locomotion up to 1.0 m/s (3.6 km/h).
Onboard sensors and intelligence provide fully autonomous orientation, mobility, and task execution without the need for a data connection. ANYmal continuously scans the terrain and obstacles to find a safe path in complex environments.
With its rugged design and IP-67 ingress protection, ANYmal’s territory includes harsh in- and outdoor environments with rain, splash water, wind, snow, and dust. The perception system operates in all light conditions including harsh sunlight and full darkness.
Lightweight, Small & Safe
At a weight of 30 kg and the dimensions of mid-sized dog (see details), the system can be handled by a single operator and features a small footprint. The ANYdrives joints with built in-built compliance guarantee safety and low noise emission.
The onboard battery provides 2-4 hours power autonomy (depending on activity) and can be easily swapped. A docking station provides ANYmal with the possibility to automatically charge without operator interaction.
While legs are great for walking, they are also useful for simple manipulation. Pushing a door open, pressing a button, or moving obstacles can be easily achieved with extensive range of motion of ANYmal's legs.
Automated tasks and missions can be intuitively programmed through the user interface. During execution, the current activity can me monitored and adapted in real-time. At any point, the operator can take over by remote controlling ANYmal to the desired place.
ANYmal is built of twelve ANYdrive robot joints, which are highly integrated combining actuation, transmission, and electronics as an enclosed device. This reduces complexity and hence the risk of failure, and for maintenance, single drives can be exchanged with ease.
A high-end RGB zoom camera can collect rich information from large distances. Computer vision algorithms interpret the images to read out the state of components such as analog gauges, liquid level meters, and valve lever positions.
A thermal camera measures precise temperature readings without physical interaction to monitor the operation of machinery. Regular scanning of the environment for temperature anomalies allows detecting risks such as cable fire before they occur.
The acoustic signature of machines and processes can be precisely captured by microphones to detect deviations from normal operation. Moreover, ultra-sonic microphones are used to pick up and localize gas leaks.
Laser sensors are used to create a precise, high-resolution 3D map of the environment. These maps are valuable data to survey environments and to detect any geometrical changes.
Advances computer algorithms are used to identify objects and humans in cameras images and laser measurements. This allows to check if for example clearance is free, fire-extinguishers are available, and no people are present in forbidden areas.
Early detection of gases contributes towards the safe operation of facilities, and sensitive gas detection sensors are used to alert about potential hazards from gas emissions.
Different gaits allow for omnidirectional motion, accurate foot placement in rough terrain and for fast locomotion on moderate and flat grounds.
The ANYdrive joints allow for interaction force control and full 360° joint rotations to enable versatile maneuvers for various locomotion and manipulation tasks.
LIDAR or stereo cameras provide 3D vision data for localization, mapping and path planning.
Customizable adapter interface to mount a pan-tilt sensor head and other application payload.
Robust & lightweight
A combination of carbon fiber and aluminium ensures high robustness and low weight.
Ingress-protected & ruggedized
ANYmal is completely sealed against dust and water ingress (IP67) and the ruggedized design protects it from impact in harsh environments.
Computing & battery power
Onboard computers provide power for complex optimizations and vision tasks and the batteries ensure about 2–4 h autonomous operation.
