The Control System of the Eight-Legged Mobile Walking Robot

The paper considers the control system of the autonomous mobile robot CS-7 with eight supporting legs, installed on four hard frames in pairs. Advantages of the chosen design: energy absence to support machine weight and simpler algorithms of trajectory and reference points motion management.

Onboard control is designed as a scalable, modular distributed low-level microprocessor system, which comprises two major subsystems: information measurement for processing sensors data and robot actuators control.

Supervisory control mode is supported by the vision system based on time-of-flight cameras and a set of ultrasonic and infrared sensors, geosteering module for local and global robot positioning. Measuring information is transmitted to the control computer via Wi-Fi module.

Software for the upper-level computer and library of functions for low-level units are developed for the implementation of various robot motion algorithms. Functions define the basic parameters of orthogonal movers depending on the given route and environment map.
