Ultrasound Turning Spider Head Arduino Nano Bluetooth

thingiverse

Created something compact to integrate an ultrasound sensor and precise positioning capabilities. Update: This is the first part of my Spider Robotter, a quadruped robot with impressive agility. Stay tuned, I'll publish it as soon as it takes its first steps! Update2: Added Fang_Nano and Head_Nano modules, providing space for Arduino Nano and Bluetooth Module HC05. This setup requires only 5 wires to pass through the neck to the body: VBAT, 5V, GND, SDA, SCL, OE. I had limited space without sacrificing large angular movement capabilities. To overcome this challenge, I integrated all components into the head. To connect the ultrasound sensor, I used a Servo-Cable to route the Supply-Trigger-Echo Pins out of the head and spliced the ground into the Servo Ground connection (brown on my model). Next, guide the wires from the top of the head down through the neck holes. Secure them with hotmelt glue after functional testing to prevent wire jams during head movement. This setup works flawlessly for me!
