A team of engineers from South China University of Technology(SCUT) have designed an amphibious robotic dog that achieves surface and underwater travel through its bio-inspired locomotion based on the canine swimming style.
Dual locomotion of the amphibious robotic dog
The robot model mimics the way dogs swim, allowing a smooth transition between different environments and achieving the best adaptation. With a double-jointed leg system and three proven swimming modes, the robot integrates speed, stability and efficiency.
The researchers tested two variants of thedog paddleoptimized for speed, and an aquatic jogging mode focused on stability. This style achieved a speed of 0.576 km/h, surpassing previous models. On land, however, the robot manages to travel at 1.26 km/h with high efficiency.
The strength of its performance comes from its calibrated structure: a precise center of mass and optimized buoyancy give it aquatic stability and terrestrial agility. This balance allows it to operate effectively on uneven ground and in bodies of water of varying depths.
This robotic dog has the potential to be used in rescue operations, environmental surveillance and military activities in amphibious zones. In addition, its modular and adaptable design allows for multiple applications such as customized uses.
The project was developed in collaboration with experts in animal biomechanics from West Chester University in the United States and with support from the University of Hong Kong in aspects of mechanical design. The publication appeared in the journal Bioinspiration and Biomimetics, edited by IOP Publishinga global benchmark in applied science.
