Ukraine is now using robotic dogs on the battlefield, the first known combat deployment of such machines. The robots were supplied by a British company and are not autonomous; they are operated by remote control, a walking version of the ubiquitous aerial drones.

“Every unit should have one of these dogs,” says Kurt, a commander in the 28th Mechanized Brigade, in an X/Twitter post on the official Ministry of Defence account.

Robots In Disguise

According to a piece in German tabloid newspaper Bild, misleadingly headlined “Robot dogs sniff out Russian soldiers” a British company, Robot Alliance, has supplied 30 of the dogs. The Bild piece states that the robots explore inside buildings, trenches and dense woodland where drones cannot go. They are used to locate booby traps and to locate Russian forces, but do not actually have sniffing sensors.

Bild states the robots can run at up to 9 mph with a battery life of up to five hours and can be controlled from up to two miles away. They quote a price of 4,000-8,000 Euros ($4400-$8,800) depending on the version. Video of Ukrainian operations in the Donetsk region shows the robot dog covered by a camouflage blanket made by German suppliers Concamo which makes it difficult to detect both visually and with thermal imaging. As soon as the robot stops moving it merges into the background vegetation.

A press release on the robots from Ukrainian fundraising platform United24 notes that data held on the robot can be erased instantly if it is captured to remove the chance of the enemy gaining any information from it.

Used In Ukraine, Made in China

The supplier named by Bild, Brit Alliance, is a security company based in the UK. They provide a wide range of services including from protection individual VIPs to safeguarding international shipping. They also help with military training and drone security and surveillance. The company did not respond to a request for information but their company site indicates they are active in Ukraine.

“We already have a wealth of experience in this rapidly developing area, deploying drones in Ukraine and across the globe,” states the Brit Alliance website.

The robot dogs are currently used for scouting in difficult locations

Brit Alliance is a security firm, not a robot manufacturer, and clearly did not make the machines themselves. It did not take internet analysts long to identify the robots in Ukraine as being Chinse-made Unitree Go2 Pros, which might be seen as the legged equivalent of Chinese-made DJI quadcopters: efficient, high-spec machines easily available at low cost.

The UniTree Go2 Pro costs $3,500 plus $1,000 shipping from China without extras and is stated as having an 11 mph top speed, in line with the Bild report. Weighing under 30 pounds, the Go2 is conveniently portable with the legs folding up for easy carrying,The Go2 Pro has an intelligent control system with multiple sets of fisheye cameras looking in all directions, plus a powerful 1.5 TFlop processor and smart software which enables it to remain stable even on uneven surfaces or rough ground. It is capable of a degree of autonomous operation such as following the operator visually, and can also do a smarter ‘side follow.’

A robot dog looks like a great toy, and many are sold as such, but what does it have to offer the military?

When Legs Beat Rotors

As a scout, the robot dog has two advantages over smaller, faster aerial drones.

Firstly, it can go places where they might have difficulty. While there are some specialist drones with shrouded rotors which can operate inside buildings, these are rare and even then flying is difficult. The robot dogs can easily explore indoor environments and search houses and bunkers, or walk through a trench system ahead of foot soldiers.

Secondly, while a drone will fly over tripwires, pressure plates and other booby traps, the robot dog will set them off. Troops know they can follow safely in the dog’s path. If it does trigger a mine or booby trap, repair or replacement is cheap and easy. It will always be preferable to put a robot in harms’ way rather than a human.

Interestingly though, operators get very attached to their machines: In Iraq, bomb disposal teams working with the much less appealing iRobot tracked robot insisted that their faithful machine be repaired and returned to them rather than replaced with a different one. One report suggested that operators were getting “dangerously attached” to their robots and treated them like pets.

Ukrainian robot dog with unknown payload

The quadruped has some other useful capabilities that put it ahead of small drones. One is its carrying capacity. Unitree says it can carry a payload of up to 9 pounds, and one image from Ukraine shows the machine carrying an unknown payload. This might be a sensor, a demolition charge, or simply a package of supplies. Ukraine has a variety of small wheeled and tracked robots which have been used to carry all of these things, and a legged robot can reach places inaccessible to other machines.

The Go2 Pro can also be fitted with a robotic arm. These are not seen on any of the images from Ukraine, but would obviously be useful for opening doors, bomb disposal and other tasks.

Another feature is the battery life. The robot can go to a location and lie in wait for an extended period. This might be simply to monitor enemy movements, but later robots might play an active role in ambushes.
