Abstract

In Cheetah-cub-S we realized an efficiant concept by implementing a spine-like structure with one DoF into a quadruped, modular and mobile platform. We increased maneuverability dramatically compared to a robot with rigid spine, while keeping controlling effort low by using intelligent mechanics. Therefore, it is possible to steer via trunk motion without changing the gait or corresponding parameters. The robot weights 1160 g at 0.1 m (height), 0.105 m (width) and 0.205 m (length). Based on qualitative tests, it is able to run 0.36 m/s and turn within a radius of 0.51 m (equivalent to 2.48 body lengths) at 0.31 m/s (equivalent to 34/s). Furthermore, we could steer the quadruped around three objects in a 7.13 m (23 s at 0.31 m/s) slalom within our test area. Due to its modularity, Cheetah-cub-S is a versatile mobile platform and components such as the spine segment, legs, motors or steering mechanism can be exchanged.

Robot

A robot is a machine—especially one programmable by a computer—capable of carrying out a complex series of actions automatically. A robot can be guided by an external control device, or the control may be embedded within. Robots may be constructed to evoke human form, but most robots are task-performing machines, designed with an emphasis on stark functionality, rather than expressive aesthetics.

Robotics

Robotics is an interdisciplinary branch of electronics and communication, computer science and engineering. Robotics involves the design, construction, operation, and use of robots. The goal of robotics is to design machines that can help and assist humans. Robotics integrates fields of mechanical engineering, electrical engineering, information engineering, mechatronics engineering, electronics, biomedical engineering, computer engineering, control systems engineering, software engineering, mathematics, etc.

Domestic robot

A domestic robot is a type of service robot, an autonomous robot that is primarily used for household chores, but may also be used for education, entertainment or therapy. While most domestic robots are simplistic, some are connected to Wi-Fi home networks or smart environments and are autonomous to a high degree. There were an estimated 16.3 million service robots in 2018. People began to design robots for processing materials and construct products, especially during the Industrial Revolution in the period about 1760 to around 1840.
