Self-Motivated Learning in Edge Devices using Curiosity

Most current AI systems, even the most advanced language models or embedded agents, are goal-driven, not curiosity-driven. They’re optimized for performance on defined tasks, not for the open-ended exploration, experimentation, or serendipitous discovery that characterizes human curiosity. Without curiosity, AI lacks the drive to seek out edge cases, explore unexpected paths, or test alternative hypotheses, things that often lead to breakthroughs in human learning. AI remains trapped within the boundaries of its training data and objectives. It doesn’t self-initiate new goals or try to make sense of unfamiliar environments unless explicitly told to do so. In dynamic environments like robotics, autonomous systems, or evolving sensor networks, a curiosity-less AI may plateau. They fail to discover new strategies or improvements unless nudged externally.

Emergent Intelligence and the Primal Layers Framework

The current trajectory of large language model (LLM) development is going to flame out. As models grow larger, they demand exponentially more data, energy, and computing power. Yet the performance gains from this scaling are already showing signs of diminishing returns, despite the massive investment. Training state-of-the-art AI models can consume megawatts of electricity, while just running them often requires hundreds of watts per user session. Compare this with the human brain which chugs along on a measely 20 watts, enough to power a dim light bulb!

Embedded System Design Principles

This is a subject that deserves its own book, and indeed, many have been written, but our goal here is to give you a solid head start. Whether you’re building your first IoT gadget or optimizing firmware for a custom PCB, there are some time-tested principles that can help you steer clear of classic mistakes. By following these principles, you can create your own unique problems rather than recreating those already made by others. These aren’t rules to blindly follow, but patterns worth understanding and adapting. Even small design decisions can have big consequences.

The PrimalBot Mobility Platform

We recently introduced the open-source Primal Layers AI framework, which is inspired by the evolutionary architecture of the human brain. When we began developing this framework, it quickly became clear that it made little sense without a body. Whether this is a profound insight about consciousness or merely a reminder that nature never produced a species of disembodied brains, we can’t say for certain. Either way, our intelligence model needs a physical form — a robot we’re calling PrimalBot.

Primal Layers — Building a Digital Brainstem

The inspiration for this article is Mike the Headless Chicken. The story of Mike is one of the more bizarre episodes in history, an accident that became a rural American legend. In 1945, a farmer in Fruita, Colorado, attempted to butcher a chicken for dinner but missed the jugular vein and left part of the brain stem intact. Amazingly, the bird survived and continued to walk, perch, and even attempt to peck for over 18 months.

Is Cognitive Sovereignty the New Arms Race?

The pursuit of Artificial General Intelligence (AGI) has ignited a geopolitical competition of historic proportions. This is a massive technological arms race, with leaders like Vladimir Putin saying whoever achieves AGI first will “rule the world”. There are parallels with the nuclear arms race, which tends to get peoples attention, but is this comparison accurate? And what does it all mean for a country like Australia, a tech savvy, middle power, caught in the middle of this tussle?

For the purposes of this article, we will define AGI as at or above human level intelligence, and acknowledge that this vague description doesn’t capture the wider issues, about what intelligence is and how we measure it.

Primal Layers — Is the Ancient Brain the Future of AI?

If you are using AI at the moment, then it is probably based on a model of the human neocortex. All of the current Large Language Models (LLMs) are overwhelmingly inspired by this approach. These architectures are great at abstract reasoning, pattern recognition, and language generation which are all tasks that are analogous to higher-order cortical functions. But is this the path to AGI? We don’t think it is, for reasons that will be explored in this article.

Flight Tracking (ADS-B) using the Raspberry Pi — 2023 Update

Interested in what planes are flying over your location? Want to know how high they are and how fast they are going? Want to build your own ADS-B (Automatic Dependent Surveillance-Broadcast) ground station that can be installed anywhere and receive real-time data directly from airplanes on your computer? In 2017 we wrote a couple of articles about tracking planes using ADS-B, and it is time for an update!

The 2017 version used a 4D Systems 2.4″ touchscreen HAT for a display, USB DVB-T TV Tuner RTL2832U + R820T as our Software Defined Radio (SDR), and ran PiAware on a Raspberry Pi 3 Model B (v1.2). The 2023 version uses all new and upgraded hardware. Read all about it, on our latest Medium article.

Arduino Memory Usage and Persistent Storage on EEPROM

There will come a point where you will want to store data which isn’t lost when your microprocessor loses power. This is particularly handy for storing calibration or configuration values, to save you having to re-calibrate some piece of hardware (e.g., IMUs, and servos) every time the power cycles. One solution for Arduino boards is using EEPROM (Electrically Erasable Programmable Read-Only Memory).

EEPROM is a type of non-volatile ROM that enables individual bytes of data to be erased and reprogrammed. It is used to store small amounts of data which are written occasionally and then read multiple times.

EEPROM is often contained within the microprocessor, and different boards will have different amounts. For example, the ATMega328P used in the UNO R3 and Nano, has 1024 bytes (1KB) of EEPROM. It is organized as a separate data space, and the EEPROM data bytes are addressed linearly between 0 and 1023.

Our example application will save calibration data for six servo motors. This is well suited to saving in EEPROM as it doesn’t often change and reading the values are not time critical. You can read the full Arduino EEPROM article on Medium.

Arduino Library for the Stewart Flight Simulator Platform

The Stewart Platform, also known as a hexapod, motion base or parallel manipulator, is a mechanical system that consists of a platform connected to a fixed base through six independently actuated legs. This arrangement allows for precise and versatile motion control in all six degrees of freedom (DOF): three translational (surge, sway, heave) and three rotational (roll, pitch, yaw).

In the context of flight simulators, the Stewart Platform is utilized to replicate the dynamic movements and sensations experienced by pilots during flight. It provides a realistic simulation of aircraft motion, enabling pilots and trainees to practice flying maneuvers, emergency procedures, and various flight scenarios in a controlled environment. By synchronizing the movement of the platform with visual and auditory cues, flight simulators enhance the training experience and help pilots develop their skills without the risks associated with actual flight.

The Stewart platform is used in car/flight/VR simulators, machine tool technology, animatronics, crane technology, underwater research, simulation of earthquakes, air-to-sea rescue, mechanical bulls, satellite dish positioning, the Hexapod-Telescope, robotics, and orthopedic surgery.

We will be using it to test our drone flight control hardware, IMUs and associated software. You can read the full Stewart Platform article on Medium.
