A quadruped robot that can carry 90 kg of weight

Quadruped robots are a class of robots that move on four legs. They are characterized by their mobility and high stability, which makes them suitable for a wide variety of tasks, from the transportation of goods, surveillance and control tasks, etc...

In 2005, the American company Boston Dynamics presented the BigDog robot. The BigDog was a cargo robot that could carry up to 150 kilograms of weight, powered by hydraulic actuators, and demonstrated that quadruped robots could perform complex tasks, but that development apparently came to a halt.

In recent years, quadruped robots have continued to evolve. In 2016, Boston Dynamics introduced the Spot robot. The Spot is an inspection robot (it can carry about 10 kg) that can travel over rugged terrain and perform inspection tasks in dangerous environments. And different functions have been applied to this robot

Quadruped robots are still in development, but they have the potential to have a significant impact on the world. As robot technology continues to improve, quadruped robots will become more common and used in a wider variety of applications.

One of the most advanced quadruped robots in the world is Barry, a cargo robot designed to transport up to 90 kilograms of weight, and to do so it uses highly efficient electric actuators. Its electric motors allow it to reach a maximum speed of 10 kilometers per hour, and it is equipped with a variety of sensors, allowing it to navigate its environment safely and efficiently.

The robot has been developed at the ETH in Zurich, and is much more evolved than the first one presented by Boston Dynamics more than 15 years ago.

The transportation of heavy loads, especially on difficult terrain, can be highly appreciated by certain segments of the market (military, builders, etc.), to avoid these arduous tasks being carried out by people, who could suffer an accident.

Applications with robots do not stop growing, and I believe that it is a field that has a very optimistic future ahead of it.
