I need a single, fully-assembled RC car that can haul grocery-sized loads from nearby shops and stream live video back to my phone. Mechanical & payload requirements • Custom 3D-printed chassis and body with enough torque and ground clearance to move comfortably while loaded with groceries. • Rear acrylic tray that can open and close automatically by servo/actuator—think “drop-box” style so I can place or retrieve items hands-free. • Secondary mount behind the tray for an Insta360-type camera; the arm or bracket should keep the lens unobstructed during motion. Electronics & FPV • Onboard Wi-Fi FPV module delivering good resolution while keeping component costs sensible. • Low-latency motor and steering control through the same wireless link. • Power system sized so runtime remains practical even when carrying weight. Mobile integration • A simple Android & iOS companion app (can be cross-platform) to handle: – Thumb-stick or slider-based driving controls – Real-time FPV video window – Button/slider to open or close the acrylic tray – Option to tilt the Insta360 mount if you can add a micro servo Deliverables 1. CAD files (STL/STEP) and any source code / schematics 2. One fully functioning unit ready to drive, with all materials supplied by you 3. Basic user guide: charging, pairing, maintenance, parts list 4. Short demo video showing operation under load I’m flexible on specific motors, Wi-Fi boards, and app frameworks as long as they meet the goals above and stay within a reasonable parts budget. Looking forward to a practical, neat build that I can start using right away.
