I understand you need an Android tablet app to act as a wireless control panel for your ESP32-based service robot. The app will scan a QR code from the robot, connect via Wi-Fi, show verified status, allow reading/writing of parameters, and include jog wheels with movement buttons. I have 20 experience in Android app development (Java/Kotlin) and have built similar control apps for hardware devices over Wi-Fi using TCP/WebSocket/REST. I’ve also integrated QR code scanning, custom UI controls, and real-time parameter updates for IoT/robotics projects. What I can deliver: QR code scanning and secure Wi-Fi connection. Live status display (green ID verification). Setup page for configurable parameters (easy to add more later). Jog wheel and movement controls with safety locks. Clean, user-friendly tablet UI. If you’d like, I can show you a quick mock-up of the UI before starting. I’m confident I can complete the first task efficiently and with clear communication.

Hi, I can develop your Android tablet app to act as a wireless UI for your ESP32-based service robot. It will scan the robot’s QR code, connect via Wi-Fi, display verified status, allow reading/writing of variables, and include the jog wheel controls with safety locks. I have experience with Android (Java/Kotlin), ESP32 Wi-Fi communication, custom control UIs, and QR code integration, so I can deliver a reliable and user-friendly solution.

@shushmobiweb6

Hello!! I HAVE CREATED SIMILAR PROJECTS BEFORE AND I CAN SHOW YOU! I have extensive experience developing Android apps that interface with hardware like ESP32 over Wi-Fi, using TCP, WebSocket, or REST protocols. In previous work, I have integrated QR code scanning to establish secure device connections, verify IDs, and display connection statuses in real-time, ensuring seamless pairing between hardware and app. For your project, the QR code scanning would initiate the Wi-Fi connection by embedding the robot’s credentials, then the app verifies the ID from the ESP32 before showing a green status indicator. The setup page can be implemented to read and write variables stored on the ESP32 using REST or WebSocket calls, with expandable fields so future parameters can be added without major redesign. The position management system will use three on-screen jog controls for 0.25 mm, 1 mm, and 10 mm movements, with lock switches defaulted to OFF and auto-resetting upon exit. Movement commands can be sent directly over Wi-Fi to the ESP32, while dedicated buttons will allow quick forward/back motions to predefined home points. I have worked on similar robotics UI projects, integrating precise hardware controls with intuitive Android interfaces, ensuring reliability and safety in real-time operations. This ensures your service robot can be operated easily by both technical and non-technical users. Best Regards Sushma S.

@iradoicic04

Senior Android dev (8+ yrs) with robotics/ESP32 experience. I’ll build a low‑latency tablet UI that discovers/connects, configures, and jogs your robot safely. - Tech stack: Kotlin, Jetpack Compose, CameraX + ML Kit (or ZXing) for QR, WebSocket (for jog), REST (config), TCP fallback, TLS where available. Clean Architecture + coroutines/Flows. - Connectivity: - Scan QR → parse robot ID/host/auth → Wi‑Fi connect/handshake. - Show verified ID with green status; heartbeat + auto‑reconnect, error states. - Setup Page: - Read/write ESP32 parameters via REST/WS (extensible schema). - Typed validation, units, dirty‑state, transactional apply/rollback. - Offline cache + versioning; param export/import (JSON). - Position Management: - Three JOG “pulse wheels” (0.25/1/10 mm) with tactile step UI. - Lock switches (OFF by default, reset on exit). - Forward/Back to home‑points with progress + limits feedback. - Rate‑limited, queued jog commands; watchdog + E‑stop hook. - Reliability & Safety: - Command ACK/NAK, sequence numbers, timeouts/retries. - Interlocks (locks required before jog), soft limits, alarm display. - Deliverables: - APK + source, API contract with ESP32, test harness, docs. - Optional ESP32 reference firmware endpoints (WS/REST), security notes. - Experience: - Android control UIs for CNC/AGV; ESP32 WS/REST; QR onboarding flows. Ready to start immediately; will align on protocol spec and provide a brief comms schema first.

@KarthikTechCon

Hi, I’m Karthik, an Android developer with 10+ years of experience building custom hardware control UIs and IoT integrations. I’ve worked extensively with ESP32 over Wi-Fi using TCP, WebSocket, and REST APIs, and I can create your tablet app with a smooth, intuitive interface — even if you’re not a programmer, I’ll ensure everything is explained simply. How I’ll Build It (in simple terms): Connectivity: The app opens the tablet camera, scans your robot’s QR code, and reads its unique ID. It then connects to the ESP32 over Wi-Fi. Once verified, a green “Connected” status shows. Setup Page: The app talks to the ESP32 to read and write settings (like speed, limits, etc.). Adding new parameters later is easy — just add them in a table in the code. Position Management: Three on-screen “pulse wheels” (0.25 mm, 1 mm, 10 mm) send movement commands. Lock switches prevent accidental moves, and reset on exit. Home-point buttons take the robot to preset positions. Why Me: Proven Android (Java/Kotlin) + IoT device integration expertise. Built QR code scanning & Wi-Fi control apps for robotics before. Can deliver clean, expandable code with documentation for non-programmers. I’ll ensure your UI is functional, safe, and easy to use, even for operators with no tech background. Regards, Karthik
