The Primal Layer model offers a biologically inspired framework for building intelligent systems from the ground up, mirroring the layered evolution of the brain.
At its core is the Foundational Layer, responsible for maintaining basic operational stability, akin to the brainstem's role in regulating heartbeat, respiration, and homeostasis. Above this sits the Motivational Layer, drawing parallels to the limbic system, which introduces drives, emotions, and prioritization of behaviors. The Control Layer governs motor planning and coordination, much like the cerebellum and spinal circuits that manage complex yet unconscious movement patterns. Finally, the Cognitive Layer reflects neocortical functions, enabling abstract reasoning, symbolic processing, and conscious decision-making.
By organizing intelligence in this layered manner, the Primal Layer model hard wires in robustness, adaptability, and safety.
The PrimalBot reflex shield project is being developed in hardware/reflex-shield, using EasyEDA Standard and the supplied reflex-circuit article as a starting point. The design brief records the intended scope, open hardware decisions and issues to resolve before schematic capture.
PCB lessons learned carries over the sourcing, supplied library, pinout, manufacturing and testing lessons from the NFC Business Card project. AGENTS.md directs future project chats to this guidance.
