From fire-breathers to sprinters, climbers and gymnasts, we have seen greater than our fair proportion of spectacular quadruped robots. Now the fourth-generation Honey Badger has added underwater walkies to the checklist of robodog capabilities.
Poland’s MAB Robotics was arrange in 2019, after its founders emerged from a scholar analysis group and constructed their first robodog. The startup’s Honey Badger quadruped has now gone by way of 4 iterations, and the most recent has developed a style for water.
As you’ll be able to see within the video under, Honey Badger 4.0 – which was launched earlier this yr – may be seen padding alongside whereas immersed underneath the water at a swimming pool to display its versatility in excessive environments.

In fact, devoted underwater drones and bots would in all probability navigate the shallows with extra finesse, however the Honey Badger does have the benefit of subsequently rising from the breakers and making its method up the seaside to proceed its mission on land.
The corporate’s Jakub Bartoszek advised us that “The method of designing Honey Badger 4.0 to satisfy the necessities for operation in water was very difficult, however we overcame the obstacles because of our strategy: construct, take a look at/break, study, and enhance. The toughest half to seal was the robotic’s actuators, the place it was essential to make them each light-weight and strong. We developed a number of prototypes and examined them to establish their limits and expanded these limits with every model. In the present day we all know construct a robotic which might function underwater, however nonetheless have a number of concepts enhance the answer additional to enhance reliability.”
We are able to additionally verify that the most recent Honey Badger is 60 cm (23.6 in) in size, stands as much as 50 cm (19/6 in) excessive and weighs in at 12 kg (26.4 lb). Along with ambling underneath shallow water, it is reckoned good for grass, concrete and gravel too.

It employs RGB and thermal cameras plus LiDAR to get round at as much as 1 m/s (2.24 mph), and is supplied with a fuel sensor. There is a 6-Ah Li-ion battery for as much as 2 hours of cable-free operation, the robotic euns on the ROS2 platform, is able to hauling a payload of as much as 2 kg, and may be managed remotely by way of 5G or a fiber-optic cable.
“The robotic makes use of energy from a built-in battery, and all movement-related computations are carried out by onboard computer systems,” confirmed Bartoszek. “The cable was used just for communication with the robotic’s operator, as commonplace Wi-Fi does not work when the robotic is submerged. We’re engaged on autonomous operation to permit inspections of commercial infrastructure, however that is nonetheless a piece in progress.”
Earlier variations rocking a jointed backbone have been shipped off to universities for analysis functions, and others have undertaken inspection duties at industrial websites in Poland in addition to getting inside heating distribution tunnels and water/sewage canals in Poznań metropolis.
“We’re cooperating with firms that handle infrastructure, a part of which is continually submerged,” stated Bartoszek. “One in every of these is an organization chargeable for water and sewage administration, the place some components of the community are greatest accessed by a system able to traversing each land and underwater environments. The underside of those areas is usually coated in rocks and particles, making motion troublesome. Throughout our assessments with companions, we have demonstrated {that a} quadrupedal robotic is a superb software, and we’re working towards commercializing the answer. Moreover, we now have began a cooperation with universities that use the robotic in analysis associated to locomotion in water. This helps us with testing and contributes to the event of the answer.”
