Robot for extreme environment exploration based on Arduino

Description: Brief description (max 300 characters) This research, hexapod robot, controlled by Arduino and remotely operated in a wireless manner. The octopus is not used here because the hexapod has a large leg space and high flexibility. In addition, the design of the hexapod also allows the robot to maintain stable movement when the terrain is irregular and uneven. And when flipping, it can also adjust itself. This robot is mainly used in the exploration of extreme environments to replace humans in exploring dangerous environments, and this research mainly focuses on the exploration of extreme caves. In order to adapt to the extreme environment, carbon fiber is designed as the main material, which is characterized by low density, high strength, high durability, strong water resistance, strong corrosion-resistance, high-temperature resistance, and high impact resistance. In addition, the power consumption of the steering gear used in this design is about 60% lower than that of the traditi

In this study, a hexapod system robot, the body is controlled by Arduino, and the remote operation is performed wirelessly. The original model of the robot was designed according to the design of the spider's body, so the original product was an octopus. However, after many experiments and data analysis, it was found that the design of the octopus is flawed. This is because the leg space is relatively narrow, and collision between feet is more likely to occur when moving, which greatly reduces flexibility and work efficiency, and the hexapod structure is perfectly solving these problems. In addition, the hexapod design also allows the robot to maintain a uniform and rapid movement speed when the terrain is irregular and rugged, and it can also adjust itself when it is accidentally turned over. This robot is mainly used in extreme environment exploration to replace humans for some dangerous exploration activities to protect human safety. In addition, the robot will also dig a safe path for humans, so that researchers can explore on a safe route in the future, And this study focuses on the exploration of extreme caves. In order to adapt to the extreme environment, this design decision to use carbon fiber as the main material, which is characterized by low density, high strength, high durability, strong water resistance, strong corrosion-resistance, high-temperature resistance, and high impact resistance. In addition, the power consumption of the steering gear used in this design is about 60% lower than that of the traditional steering gear. After experiments, it is concluded that it can run for more than 10 hours under a fully charged condition, which is enough to work for a long time under the cave. The Arduino is used as the core because it has multiple interfaces and supports multiple serial communication at the same time. It can sense the environment through a variety of sensors, and the device is equipped with a light sensor, color sensor, and temperature sensor for research and exploration. In addition, it is also equipped with an infrared sensor for obstacle avoidance. The function of the main components Low light night vision The low-light night vision device will emit an infrared beam outward, illuminate the target, and convert the infrared image reflected by the target into a visible light image, so as to observe, can operate under a completely dark cave, and transmit real-time images to researchers, In order to facilitate researchers to study the internal structure of the cave. Infrared obstacle avoidance uses the principle of triangulation ranging. Infrared emitter The infrared emitter emits an infrared beam at a certain angle. After encountering an object, the light will return in reverse. After detecting the reflected light, the distance of the object can be calculated through the geometric triangle relationship on the structure. When the distance is close enough, the robot will avoid obstacles. Ultrasonic sensor The robot will emit ultrasonic waves, and the ultrasonic waves will bounce or penetrate after hitting the obstacles. The robot will transmit the data obtained in real-time to the user terminal through the Bluetooth program, and then the researchers can use the computer simulation program to get the three-dimensional structure of the cave. It is roughly drawn. Robot arm The robot arm can activate the small holes on the tips of the four arms behind it under the control of the Arduino. Then, Through the nano-suction technology, which uses vacuum, negative fluid pressure and millions of nano-sized suction cups to securely adhere any object so that the sample will be sucked into the sample micro storage. After returning to the laboratory, the researchers can draw and store the data and samples they want to search in the cave to the upper sample storage. After the robot returns to the laboratory, the researchers can study the samples
