Hi, I design embedded control circuits — ESP32 systems, DC motor drive stages, power protection, and PCB layout — and this project fits well. For your 30–35 kg outdoor robot with 24V motors, my approach: ESP32 core with clear pin mapping for motor driver, RC receiver, sensors, and emergency-stop Motor drive: 24V-rated driver (H-bridge/driver IC) for forward/reverse, left/right, and PWM speed control Power system: Buck regulation to 5V/3.3V, with fusing, reverse-polarity, and inrush protection Safety: Hardware e-stop cutting motor power directly, plus current/thermal protection Deliverables: Full schematic, wiring diagram, PCB layout (Gerbers), BOM, and test documentation I'll pay close attention to isolating motor-driver noise from ESP32 logic and using vibration/weather-rated connectors, given the outdoor/inclined-panel use case. Examples of similar circuit and PCB work are on my profile. Happy to confirm quotation and timeline once motor current ratings and RC module choice are set. Best regards,

Hi, I can design the complete ESP32-based control circuit for your remote-controlled solar panel cleaning robot, including 24V DC motor control, PWM speed control, safety protection, battery power management, sensor inputs, and PCB-ready documentation. My approach will be to first confirm motor ratings, battery type, remote-control method, sensors, cleaning mechanism load, enclosure limits, and connector needs. Then I’ll prepare the schematic, ESP32 pin map, motor driver section, power regulation, fuses/protection, emergency stop, remote receiver interface, and wiring diagram. I’m comfortable with ESP32 systems, 24V DC motor control, motor drivers, PWM, battery-powered robots, outdoor hardware, protection circuits, sensor integration, PCB layout, BOM preparation, and prototype troubleshooting. Deliverables: * Complete circuit schematic * ESP32 pin mapping * Motor driver/control circuit * Forward/reverse and left/right logic * PWM speed control * Emergency stop and protection * Battery regulation/power distribution * Sensor and remote receiver interface * PCB layout if required * BOM with specifications * Gerbers/manufacturing files * Wiring and testing notes I’ll focus on a reliable, serviceable design suitable for a 30–35 kg outdoor solar panel cleaning robot prototype and future production refinement. Best regards Ankit

A 30-35 kg robot on inclined panels means motor stall current, thermal rise, and safety cutoffs can't be afterthoughts — they have to be designed in from the first schematic. I've built ESP32-based control systems for similar load conditions, including a custom PCB for a 24-point servo controller and a battery-powered audio device with proper power management. Here's what I bring to this: → I'll design the full circuit with ESP32 pin mapping, motor driver selection sized for your 24V motors' stall current, and a power distribution board with fusing and voltage regulation → Remote control via BLE/2.4GHz receiver integration, with PWM speed control, emergency stop, and sensor interfaces for limit switches or tilt detection → Full stack capability: schematic, PCB layout, BOM with real supplier links, and Gerber files — plus basic testing documentation for your prototype phase I've shipped custom PCBs that survived 50-unit production runs and outdoor conditions, so this design will be built for reliability, not just a bench demo. Happy to walk you through my approach and past work on a chat.

We at HardFault can design the complete electronics and control system for your ESP32-based solar panel cleaning robot, including 24V motor control, wireless remote interface, battery management, protection and sensor integration. We’ll handle the power distribution, motor drivers, forward/reverse and PWM control, emergency stop, fusing, connectors, ESP32 firmware, PCB design, BOM, wiring diagram and manufacturing files. The design will consider the 30–35 kg tracked robot, inclined solar panels and outdoor operating conditions. We have experience with ESP32, battery-powered embedded systems, DC motor control and PCB development. **We can also share relevant examples of our previous robotics, ESP32 and motor-control work directly in the chat** for you to review. Would you like us to start by reviewing your motor specifications and battery setup so we can select the right driver and protection architecture?

Your solar panel cleaning robot needs a solid, serviceable circuit, ESP32 brain with proper motor control and protection for that 30-35 kg build. I've designed similar battery-powered robot control systems before, so this is right in my comfort zone. Here's what I bring to this: → I'll design the complete circuit around an ESP32 with dual motor drivers handling your 24V DC motors, PWM speed control, and safety features → Full schematic, ESP32 pin mapping, power distribution with fuses and protection, plus remote-control receiver integration → I'll include a complete BOM with component specs and a PCB layout, ready for manufacturing → I can deliver everything within 5-7 days, including testing documentation I have the ESP32 and motors with and have done similar work before, so I can test the connection and firmware at my end to ensure the code is tested before delivery.

Hi, I’m interested in this ESP32-based solar panel cleaning robot controller. Before quoting accurately, could you share the 24V motor datasheets, motor quantity/current ratings, battery specification, remote-control type, required sensors, and whether the PCB must be production-ready or only for prototype use? This will let me define the motor driver, protection and power architecture correctly.

@sunnykushwaha89

Hello, Designing electronics for a 30–35 kg tracked robot on inclined solar panels requires robust high-current motor drivers, thermal dissipation, outdoor reliability, and fail-safe protections.

High-efficiency DC-DC buck stages for 5V/3.3V logic. * **24V Motor Drive System:** High-current H-bridge architecture (e.g., BTS7960/BTN8982 or discrete MOSFETs) with ample stall-current headroom for drive tracks (differential steering) and the roller brush motor, featuring smooth PWM speed regulation. * **ESP32 & Wireless Integration:** Clean GPIO mapping for RC receivers (SBUS/IBUS/PWM) or ESP-NOW control, battery telemetry, and opto-isolated interfaces for tilt (IMU) and edge/fall-prevention sensors. * **Rugged PCB Layout:** Heavy-copper KiCad layout with thermal relief, reinforced high-current traces, and vibration-proof terminal blocks/XT60 power connectors. **Deliverables:** 1. Complete KiCad schematic and PCB project files. 2. Manufacturing package: Gerbers, NC Drill, Pick & Place (CPL), and complete BOM with verified MPNs. 3. System wiring/interconnection diagram and bring-up guide.
