Electronics & Firmware Feasibility Review — Electromechanical Consumer Boxing & Fitness Product

Overview Seeking an electronics and firmware engineer to review a proposed electromechanical boxing/fitness product and provide a structured feasibility assessment. Initial scope is review and assessment only — no design or development work at this stage, although if proposed product is deemed viable, there will be an opportunity for further end-to-end development and design for the suitable candidate. The intended product is a piece of striking equipment that trains both offense (as a typical striking bag would allow) and defense (reactions from the user required due to actions created by the bags arms). It incorporates both mechanical and electronic components, aimed to mass produce for a commercial market. Full product details and the existing mechanical engineering documentation will be shared with the short listed candidates. Background A mechanical feasibility study has been completed for the product involving spring-driven reactive arms, electronic triggering, and motor-driven reset. The mechanical architecture is defined. This brief is specifically for an electronics and firmware engineer to assess what has been proposed from an electronics perspective — what is viable, what carries meaningful cost or complexity implications, and what could be improved. Scope of this engagement Review the proposed electronic architecture as documented in the mechanical feasibility study and provide a written assessment covering: What is technically feasible as proposed What is feasible but carries significant cost or complexity implications worth flagging What is not recommended or unviable as proposed, with reasoning Component category recommendations where the proposed approach has better alternatives Firmware scope assessment — complexity, development time, and any architecture considerations Any suggestions or improvements to the proposed electronic approach Approximate recommended next steps in the prototype phase Required experience Embedded systems and firmware — Arduino, ESP32, STM32 or similar Motor control — DC motors, PWM drivers, limit switch or encoder integration Sensor integration — force sensitive resistors, piezo sensors, solenoid drivers Power electronics — battery or AC-DC supply design for a consumer product Practical product development experience — component cost awareness, design for manufacture Deliverable A structured written assessment covering the scope above. Concise and actionable. Note: Successful candidate/s will be asked to sign an NDA before receiving the mechanical study and full product brief. Rate is somewhat flexible pending the final proposed scope and deliverables on offer
