Servo crawler with Arduino Nano

thingiverse

I'm testing a crawler that relies on three steady servos, but unfortunately, it doesn't work properly when limited. I tried it myself. This crawler uses an Arduino Nano paired with a shield from Amazon - here's the link: https://www.amazon.com/ with a 9V battery. It's a snug fit, but with some force, it fits okay. The design also includes a slot for attaching an Ultrasonic sensor.
