I’m building an industrial-grade robotic setup and need a sharp embedded-systems mind to move the control electronics from concept to reliable hardware-in-the-loop operation. The work centres on firmware that drives motors, interprets sensor data and communicates over CAN bus or OBD-II–style diagnostics. Most of the prototyping will happen on Arduino or ESP32 boards before we freeze the design onto a custom PCB, so familiarity with Altium Designer or KiCad for schematic capture and layout is essential. Here’s how I see the collaboration flowing: • Translate high-level motion requirements into C/C++ firmware with clean, well-commented code. • Select, integrate and tune motor drivers, encoders and safety interlocks so the robot meets industrial-speed repeatab...

I have a piezo-based wet/dry sensor concept that relies on tracking resonance changes in a PZT ceramic between 20 kHz and 500 kHz. When the tip is in air the vibration is high-Q with a large voltage swing; when any liquid covers it the amplitude drops, the Q-factor falls, and both phase and resonant frequency shift. I now need an electronics specialist who can turn this working principle into a repeatable, field-ready solution. The job covers selecting the drive topology, designing the analog front-end, and implementing a small digital section that continuously excites the ceramic, samples the returning signal, and decides “wet” or “dry” in real time. Accuracy, low noise, and robust thresholding against temperature or viscosity changes are essential. Delive...
