This is the design and building of my first all -Terrain robot!
The original idea was for a beginners all-terrain robot that could easily cross rough ground and long grassy fields, nothing major. This is the first "hobby" robot that I've built since university so its been a learning curve, I'm used to industrial robotics and automation s
ystems.
I looked at a few designs that had independent suspension etc but with limited "hobby" robot experience I went simple and "cheap" so excuse me for the robots simple design.
Components.
- Two 200W 24Vdc motors
- Sabertooth dual channel 25amp motor speed controller
- Two Haze 12V 44ah AGM lead acid batteries
