Build a Goal-Directed Doorbell Robot with ACT-R Cognition on Raspberry Pi 5

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Move beyond motion-activated cameras. The Smart Doorbell Camera Kit v7 lets you assemble a mobile robot that patrols your doorstep and uses an ACT‑R cognitive model — the same architecture used in advanced human‑memory research — to give the robot goal‑directed behaviour and short‑term working memory. It recognizes familiar faces, remembers previous encounters, and decides whether to silently alert, greet, or investigate.

What You'll Build

You’ll construct a wheeled robot on a sturdy chassis, powered by a Raspberry Pi 5 8GB and booting from a fast NVMe SSD. The Pi Camera Module 3 captures real‑time video, while the INMP441 I2S microphone picks up audio. Two DC motors driven by a Cytron motor driver allow the robot to patrol a defined area. The heart of the project is the ACT‑R cognitive layer: it maintains a working memory of who arrived and when, sets goals like “verify unknown face,” and triggers actions — turning toward a sound, rolling to a pre‑set greeting point, or ignoring a pet — all without one line of reactive if‑else code.

What You'll Learn

• Implementing ACT‑R cognitive architecture on Raspberry Pi 5 for goal‑directed AI
• Integrating a Pi Camera Module 3 and I2S microphone for vision and audio pipelines
• Controlling DC motors with a Cytron motor driver to enable autonomous navigation
• Building a working memory module that stores visitor profiles and makes context‑aware decisions
