Autonomous Recon Ball Robot Design

I am developing a self-propelled, ball-shaped reconnaissance robot that must roll freely indoors and outdoors across mixed terrain, stream or log data, and return safely for re-use. I need a complete, production-ready engineering package and a functional prototype. Scope of work The robot has to propel itself by internal actuation, maintain stability while turning, and withstand bumps, dust, and light rain. It should carry a modular sensor suite for video, audio, and future environmental probes, then transmit data in real time to a ground station or mobile app. Navigation can be fully autonomous or tele-operated, but it must include obstacle avoidance and a “return-to-home” routine. Please cover every discipline—mechanical, electronic, firmware, and software—and keep manufacturability in mind. Deliverables (all required) • Complete 3D CAD and 2D fabrication drawings of the spherical chassis, drive system, and sealing features • Bill of materials with supplier links and estimated costs • Schematics, PCB layout (if custom), and wiring diagrams • Embedded code (Arduino, STM32, Raspberry Pi, or equivalent) plus ROS nodes or custom control software • Computer-vision or sensor-fusion scripts for navigation and data capture • Assembly guide, calibration procedures, and maintenance notes • Fully built, tested prototype with video demonstration of indoor and mixed-terrain outdoor operation Acceptance criteria 1. Prototype rolls continuously for at least 30 minutes on one charge, switching between smooth floor and grass/gravel. 2. Live HD video feed and onboard recording work without dropout over 30 m line-of-sight. 3. Robot completes a 10 m outbound run, avoids three random obstacles, and returns to the start point autonomously. 4. Documentation is detailed enough for a third party to reproduce the build. If you have experience with spherical robots, reaction-wheel or pendulum drives, ROS, and ruggedized enclosures, I’d like to see examples. Let me know your preferred toolchain and the timeline you can commit to for design iterations, fabrication, and shipping the prototype.
