Overview

For a cave exploration robot, moving through narrow winding paths and over obstacles is an unavoidable requirement. This robot has a flexible "neck" that allows it to bend around obstructions and a locomotion method consisting of wheels with "tentacles" covered in latex that help the robot grip and climb over obstacles efficiently. This flexibility allows the robot to conform to highly uneven and challenging terrain.

The chassis is designed in such a way that makes it easy to access all the parts placed inside of the robot. The modular chassis is composed of lateral parts where the motors are attached; a base floor where all the electronics are fixed; and some bars on top providing the body with sufficient rigidity. The chassis is covered with a plastic case, sealing the contents of the robot to prevent water incursion. In order to facilitate exploration activities, a wireless camera and a light source were incorporated into the vehicle. These devices, as well as the robot’s movement were controlled through a main board with wireless serial communications and a PC with Lab‐View. The main control panel in LabView allows control of the direction of the robot and showed the images acquired by the camera in real time.

Six DC gear motors were distributed throughout the body, three on each side. Each motor, selected to provide a torque sufficient to lift the weight of the whole body by it‐self, was attached to a wheel.
