Walking behaviour of a hexapod robot using a wind direction detector

A hexapod robot was developed to explore a field and gather agronomic data such as soil nutrients, temperature, humidity and plant growth. The robot was navigated by using a wind direction detector consisting of four airflow sensors. The hexapod robot successfully navigated in an upwind direction using the wind direction detector. It remained at a location under calm conditions but walked upwind as soon as the wind began blowing again. The feasibility of using the robot for tracking a gas source was also examined using a CO 2 sensor.
