Any bio-inspired robot needs hardwired instincts. That means giving PrimalBot the ability to sense its environment, protect itself, and react instantly, without waiting for the processor. To achieve this we had to design a custom shield that provides dedicated reflex circuits. On it, we’ve integrated:
- Four hardware reflex loops that can bypass the controller and activate/stop the motors instantly.
- A Pulse Width Modulation (PWM) generator to enable speed control of the motors.
The shield is designed to act like a robotic brainstem, handling the critical low-level functions that keep the system safe and responsive, while freeing higher-level layers to focus on learning, planning, and decision-making. In this article, we’ll walk through the design and simulation process of the reflex loops.
