I’m looking for a maker who can build (and document) a functional prototype of an RC car and Rc car which needs to be build in budget with requirements mentioned that doubles as a 1 kg grocery hauler. I will rely on a mobile-app interface, so please keep every control—driving, tray actuation, and FPV video—inside a single Android & iOS solution. Core requirements • Chassis and drive: Choose or fabricate a sturdy radio-controlled chassis. Select motors with enough torque to move at a reasonable indoor speed while carrying up to 1 kg. Feel free to recommend brushed or brushless—performance matters more than the exact type. • Connectivity: Integrate an on-board Wi-Fi FPV module with transmitter/receiver that streams live video to the same mobile app used for driving controls. • Camera mounting: Add a rear mount that fits an Insta 360 (or similar) action cam; vibration damping is a plus. • Payload system: Install an acrylic tray sized for standard grocery bags. The tray must open and close automatically from the app (servo, linear actuator or other mechanism of your choice). • Mobile control: Provide or customise an app that works on both Android and iOS, offering: – Real-time FPV feed – Forward-reverse, steering, and speed control – One-tap tray open/close • Power & electronics: Design a tidy wiring plan with a single battery system if possible, plus safety cutoff. • Documentation: Supply the BOM, circuit diagrams, firmware/source code, and a short user guide so I can reproduce or maintain the build. I’m flexible on materials as long as the final unit is reliable, compact, and cleanly finished. Let me know the approach you’d take, key components you have in mind, and an estimated timeline for the deliverable unit
