### AI overview

The Petoi Quaddle is a mini robot dog designed for learning robotics, coding, physical AI, and 3D printing. It uses an ESP32-S3 motion core, optional AI hardware, OpenCat firmware, and multiple programming environments. Petoi launched it on Kickstarter with three models and planned December 2026 shipping.

### Source excerpt

If you are not into ducks, but still would like to play around with physical AI, the Petoi Quaddle is a mini robot dog equipped with 4 servos controlling its legs and is designed to help people learn robotics, coding, AI, and 3D printing. The robot is powered by an ESP32-S3 motion core for servo control and wireless connectivity, and an optional ESP32-S3 AI core to enable voice commands and Smart Home control. The robot can walk, strafe, spin, talk back, and react to the user's touch. Three models are available depending on the user's requirements: Builder, Buddy, and Scout. A Raspberry Pi Zero can also be mounted on the top in place of the ESP32-S3-based AI core. Petoi Quaddle runs OpenCat open-source firmware (Arduino) already used in the earlier Petoi Bittle robot dog, first introduced in 2020. The robot can be programmed in a visual programming IDE with drag-and-drop [...] The post Petoi Quaddle - A mini robot dog for physical AI experimentation (Crowdfunding) appeared first on CNX Software - Embedded Systems News.

### Source excerpt

Layered Ventures LLC has launched the TickrCast, an expandable HUB75 LED ticker display built around an ESP32-S3. The TickrCast ships as a full consumer product designed to display live esports data, traditional sports scores, social media metrics, and flight tracking across a daisy-chained array of panels. Unlike a typical LED matrix development board, the system is a complete product with a custom controller board, plug-and-play panels, power connectors, a companion app, and an expandable enclosure. The display starts with two panels and can be expanded by adding additional panels, with the company targeting configurations of 10 or more panels. The system is controlled through Wi-Fi, while Bluetooth LE is used for initial provisioning, and the manufacturer provides more than 30 plugins at launch with no subscription required. The platform also supports signed over-the-air (OTA) firmware updates and hardware flash encryption for improved device security. TickrCast controller specifications: ESP32-S3-WROOM-1U wireless module [...] The post TickrCast - An ESP32-S3 HUB75 LED ticker display with server-side rendering and OTA (Crowdfunding) appeared first on CNX Software - Embedded Systems News.
