I need a complete 3D CAD model of a pipeline-inspection robot that can reliably navigate through sewer pipes larger than 24 inches in diameter. For now, its job is movement, camera and led light, so the design must leave logical mounting points for future sensors without compromising balance or clearances. Because I will be printing the parts myself, every component has to be optimized for standard FDM printers (220 × 220 × 250 mm build volume) with minimal support material and straightforward post-processing. Think in terms of interlocking or bolted sections that can be printed flat, then assembled with off-the-shelf hardware. Deliverables • Native CAD files (Fusion or Onshape ) plus exported STEP and STL for each printable part • An exploded view or b...

Your scope includes performing the calibrations to manufacturer specifications, recording as-found and as-left data, issuing traceable calibration certificates, and updating the skid’s logbook bef...

...braces—cleanly organized so every major piece sits in its own assembly. You’ll be working from a high-resolution photograph I’ll supply; the goal is to match the overall proportions and clearances of a typical patient-lift, even though exact factory dimensions aren’t available. File structure matters: each assembly must be logically named so I can later drop in power-assist motors, batteries, sensors, and AI hardware without re-factoring the file. Keep joints and motion limits realistic so future kinematic studies run smoothly, but don’t add electronics, motors, or code at this stage. Deliverables • Native Fusion 360 design file (.f3d) with assemblies properly referenced • STEP export for quick previews • Short read-me noting any...

...from concept to a working prototype of a Quantum Computing + IoT framework that tackles Urban Heat Islands end-to-end: we will monitor conditions continuously and then act on the insights to mitigate them in real time. Scope and context • Data will flow in from a dense mesh of ground sensors capturing temperature, humidity, CO₂ and overall air-quality metrics every few seconds. Satellite or weather-station feeds could be folded in later, yet the first milestone is rock-solid performance with the on-site sensors. • On the quantum side, I want algorithms that can handle the heavy analytics load—predictive hot-spot mapping, optimisation of cooling interventions, maybe even near-real-time scheduling of adaptive shading or misting systems. Qiskit, Cirq or s...

I already hold the patent designs for a pair of smart glasses; now I need them to come alive as a working prototype that I can place in front of investors. The hardware must fuse artificial-intelligence-driven voice recognition, an in-lens augmented-reality overlay, and continuous health-monitoring sensors, all packaged in a form factor true to my drawings. Core expectations • Firmware that supports hot-word voice commands and natural-language interaction processed on-device or via a lightweight edge AI stack. • A transparent AR display that renders contextual cues directly on the lens while maintaining normal vision. • Integration of basic biometric modules (heart-rate, step count, and SpO₂ ideal) with real-time data streaming. • A companion mobile app ...

...that streams live readings from user-owned sensors. Each time a new sensor is registered the backend writes a user-to-device mapping into Redis; this mapping is then used to route all subsequent messages. Right now the Redis part is failing. The web-app itself loads, the registration call completes, and a key does appear in Redis, yet the association is not updated correctly so the new sensor’s traffic never reaches the UI. In short, the Redis server is the bottleneck and it isn’t updating with new sensors as expected. What I need from you: • Trace and fix whatever in Redis (key pattern, Lua script, TTL, race condition, Pub/Sub channel, etc.) is preventing a clean update when a sensor is added. • Prove the fix by registering multiple new se...

...Simplicity Studio or any GCC-based toolchain compatible with the chip. 2. A concise header/API that my application code can call to: – write/read registers – upload a packet buffer – initiate TX and check status flags 3. A brief read-me explaining build steps, pin assignments, and an example sequence that sends a test frame. If you have prior experience with Silicon Labs wireless parts or any SPI-centric bare-metal work, this should feel familiar. Low-level efficiency matters more than a fancy UI, so a straightforward CLI test utility is plenty for demonstration. I will test by flashing your build, driving it from my host MCU, and confirming that packets appear exactly as expected on the analyzer. Once the demo passes, we can polish or e...

Project Title: Mechanical Validation & Prototyping: 60GHz RF Optic Enclosure (ULTEM™) Project Overview We are seeking a Senior Mechanical Development Engineer to move a patented RF-enhancement technology—the RF BENDER™—from simulation to physical benchmarking.
