Đầu cho Freenove Hexapod

The Freenove Hexapod Robot Kit is an excellent value hexapod kit that can be controlled from PC or phone or a supplied rf controller. 

It is available from ebay or amazon or aliexpress. Here's the Amazon UK link https://www.amazon.co.uk/Freenove-Raspberry-Crawling-Detailed-Tutorial/dp/B07FLXFDZ1?th=1. 

One nice thing about the kit is that it exposes certain pins for further expansion possibilities. I decided that what the hexapod needed was a head with a dot matrix mouth and ultrasonic sensor 'eyes' that could scan from side to side and provide the necessary information to code in some object avoidance. I also added a buzzer for good measure!

Note this model uses the US-100 Ultrasonic Distance Sensor not the HC-SR04 which has slightly different dimensions (and didn't play nicely with the existing code).
