Hi danctag, Last week I built a very similar 2‑wheel robot with proximity sensing and a 3D‑printed shell, so I’m confident I can handle this really well. My Questions. - Which controller do you prefer (Raspberry Pi vs Arduino/ESP32)? Do you need Wi‑Fi/Bluetooth or audio playback from files? - What battery type/capacity and runtime do you expect, so I can size regulators, motor driver, and wiring safely? My Suggestions. - Use a TB6612FNG (or DRV8833) motor driver instead of L298N for cooler, smoother PWM and longer battery life. - Use a ToF sensor (VL53L1X) plus a small bumper switch as a fail‑safe; it handles soft/angled objects better than ultrasonic alone. My Execution Plan. - Review your STL files and requirements; confirm components and behaviors. - Finalize BOM; design wiring diagram, fusing, power rails, and mounting points. - Adjust STLs for standoffs, cable paths, and easy assembly. - Bring up firmware on the chosen controller; add motor ramping and simple straightening. - Integrate sensors; code a clear state machine (idle, react, reposition) with tunable params. - Assemble prototype; tidy harness with JSTs; balance weight and CG. - Test on bench and floor; tune speeds/thresholds; check thermal and brown‑out. - Add LED ring and buzzer (optional) with simple patterns/tones. - Deliver code, diagrams, setup notes, and a test checklist; support handoff and quick tweaks.

Hi, I reviewed your Madison Orb v1 concept and it aligns strongly with my experience in embedded robotics, motion systems, and interactive prototype development. I’m a mechatronics/embedded engineer with 15+ years of experience, having developed 20+ robotic and interactive hardware prototypes using Raspberry Pi, ESP32, motor-control systems, LED behavior engines, and custom 3D-printed enclosures. Approach: ✅ I will refine the mechanical integration of the egg-shaped enclosure, wheel geometry, caster positioning, wire routing, and serviceable internal mounting structure. ✅ I will integrate Raspberry Pi 5 (or optimized alternative), quiet DC gear motors, motor drivers, sensors, audio system, and coordinated LED lighting architecture. ✅ I will implement smooth low-speed motion control and structured behavioral states with synchronized expressive lighting and ambient interaction logic. ✅ I will provide organized firmware/software, wiring diagrams, BOM, assembly guidance, and validated prototype testing documentation. Questions: ✅ I need to confirm target dimensions, weight, and estimated runtime requirements for motor/battery sizing. ✅ I want to verify whether local/offline voice interaction is preferred or if cloud-connected audio processing is acceptable. ✅ I need clarification on preferred LED technology (WS2812, APA102, diffused segments, etc.) and brightness expectations. Best, Yaroslav

@electronicsdone

Dear Client, I can help turn your existing mobile robot concept and STL direction into a working physical prototype. I like that the scope is practical: 2-wheel drive, basic sensing, simple behavior states, LED/audio feedback, and functional assembly. That is exactly the right level for an early prototype — prove reliable movement and response first, then polish later. I would handle: ✅ controller selection: Raspberry Pi, ESP32, or Arduino based on what is actually needed ✅ motor driver, battery, proximity sensor, and feedback integration ✅ differential-drive logic: forward, reverse, turn, stop, react ✅ basic state behavior: idle, active, reposition, obstacle response ✅ enclosure fit review so the electronics and motors mount cleanly ✅ wiring diagram, readable code, and setup notes For this build, I would keep the design simple enough to work reliably instead of making it unnecessarily complex. One useful question: Do you want the first version optimized for fastest functional demo, or cleaner mechanical/electrical integration for easier later iteration? If you share the STL and rough size target, I can suggest the cleanest build path. Best regards, Prat PCB Must Innovations

@tetianam8

⭐⭐⭐⭐⭐ Madison Orb v1 has the right priorities. The shift from a “cute robot” toward a calm ambient presence changes the engineering decisions completely — movement curves, lighting transitions, acoustics, wheel geometry, even shell tolerances all need to support that emotional feel. I’d approach this as a tightly integrated mechatronics prototype: • Raspberry Pi 5 handling behavior/audio/state logic • Dedicated MCU (ESP32) for real-time motor + LED control • Quiet geared DC motors with acceleration ramping and low-RPM tuning • Hidden caster geometry optimized for stable, intentional turning • Coordinated LED language between visor ring + body band using soft transitions and low-latency animation control • ToF sensing for subtle environmental awareness without “robotic twitchiness” I can help refine the STL set for: • internal mounting structure • cable routing/serviceability • thermal and speaker airflow • wheel/caster alignment • shell fastening and assembly repeatability Deliverables would include: • working prototype architecture • wiring + BOM • readable modular codebase • behavior-state framework • assembly/setup documentation • enclosure revision recommendations Relevant experience: embedded robotics, ESP32/RPi systems, motion control, interactive LED systems, compact enclosure integration, and emotionally-driven interaction hardware. That’s what will make the prototype feel “present” instead of gimmicky.

@Feriver

Hello, I understand you’re building the Madison Orb v1 as a calm ambient companion robot with an egg-shaped enclosure, glossy visor, dual-wheel drive with hidden caster support, and a strong focus on slow, intentional motion and emotional presence through a unified LED system. The core challenge is not complexity but refining movement stability, state-based behavior, and synchronized light expression to create a believable ambient “presence” rather than a toy-like robot. I will design and implement the full prototype system including motor control (smooth low-speed differential drive with caster compensation), sensor integration (ToF/proximity), and a structured state machine for idle, attentive, reacting, docking, and rest modes. I’ll also implement coordinated LED behavior across the front ring and body band, plus audio I/O for basic interaction. Additionally, I will review and refine your STL files for motor mounts, caster integration, wiring routing, serviceability, and assembly practicality, along with wiring diagrams, BOM, and clean documented firmware. This will be approached as a rapid, hands-on prototyping cycle focused on physical validation of motion feel, lighting coherence, and enclosure fit—not overengineering. I can start immediately with system architecture and hardware mapping to ensure fast alignment before implementation and iteration. Thanks, Asif

@mahmoudralizadeh

Hi this could be performed by clarifying sensors, outputs, and functions. Then choosing a board an finally providing code and if it was necessary, a specific PCB for the project can be built. bests
