Our latest technical update features a look at the (Fly Mind Altering Device) system in full swing. If you've seen the bj-full-120fps.mp4 demonstration, you’ve witnessed the backbone of our real-time tracking architecture.
This video file refers to technical documentation from (the Fly Mind Altering Device), an open-source hardware system developed for real-time tracking and optogenetic/thermogenetic stimulation of fruit flies. The "120fps" in the filename highlights the system's capability to process image data at high speeds for precise targeting. 🔬 Project Overview: FlyMAD bj-full-120fps.mp4
: Built using Python and the Robot Operating System ( ROS ) for interprocess communication. 📝 Blog Post Draft: Mastering Real-Time Neural Control Our latest technical update features a look at
At lower frame rates, the latency between a fly moving and the laser adjusting can lead to "misses." By pushing our image processing and control logic to 120fps , we reduce this lag significantly. This allows for sub-0.2mm precision, ensuring that the light or heat is applied exactly where intended, whether that's the thorax or the head. The "120fps" in the filename highlights the system's
The video bj-full-120fps.mp4 serves as a demonstration of the system's architecture, which integrates:
The system operates on a dual-camera setup. A wide-angle camera maintains a lock on the fly's global position within the arena, while a second, high-magnification camera targets specific anatomical regions. By utilizing Thorlabs 2D galvanometers, we can steer a laser to deliver precise optogenetic or thermogenetic stimulation—all while the fly moves freely.
