Q-Octo – We reinvented the wheel with a compact endurance rover
Hello, inspired by Q-Whex [1], we built Q-Octo, a compact rover with eight quasi-wheels (160° cut out). The wheel design enables the rover to climb over larger objects while rolling smoothly on flat ground. Q-Octo uses four drill batteries, two Xiaomi Cybergear motors (vs 6 motors for the Q-Whex), two Raspberry Pi Pico’s (one with WiFi), a Pimoroni Pico display, and a variety of 3D-printed & laser cut pieces for the body. The rover can be configured via its Wi-Fi access point as it hosts a web socket server with mDNS and a captive portal. Messages are encoded via Flatbuffers. It is driven…

I made a Raspberry with Qwen my local car AIAug 2026 · github.com · ▲146Found that you can actually run a 35B Qwen model on a Pi with very impressive intelligence and stability. Built connectors for car ODB to read all about car internals, and manufacturer's cloud service for stuff like changing AC or opening/ locking doors. Gave it info such as the full car manual. And then hooked it up with my other agents in our discussion room! So now it can answer car questions such as "when should I add oil and what kind of oil?" and help you fully offline, and when online talk with the agent family that includes all the most powerful models so they know how the car…

I am not sure if this is fits the HN community, but I am posting it here if people are interested. This is the current iteration of the car: http://i.imgur.com/ko8YBh.jpg Details: I wrote a simple android app that streams the accelerometer data from the phone to the pi over a simple socket. The pi then uses this data to drive the DC motor and the servo motor. Tilting the phone to control the car feels very natural. In this[0] pic you can see the wifi dongle I've used. I am using Adafruit Occidental v0.2[1] as my OS because it has support for my wifi dongle. It also makes some hardware…
