Application context
How this product is typically engineered
Reference photos show control and user-interface boards, a wireless section, labeled safety and sensor connectors, and a mainboard with repeated power channels.
System architecture
Example architecture
One battery-platform architecture to evaluate routes a protected high-current bus to traction, blade and auxiliary actuators. DC/DC rails can supply the real-time controller, sensor interfaces, wireless board and display; local safety logic should arbitrate motion commands.
Engineering risks to resolve
Decisions to close before release
- Handle motor-start, stall, and regenerative transients without disturbing sensing or wireless control.
- Define and validate blade-stop behavior for lift, tilt, collision, and internal-communication faults.
- Evaluate condensation, mud, fertilizer contamination, vibration, and heat loading in the sealed enclosure.
Validation planning
Checks to define before production
- Define fault-injection tests for lift, tilt, collision, sensor disagreement, motor stall, and communication timeout.
- Set methods to measure blade stopping time, slope start and stop behavior, charging faults, and full-load temperature rise.
- Agree whether rain, ingress, damp-heat, corrosion, vibration, motor EMC, ESD, EFT, and wireless-coexistence tests apply.
RFQ planning
Files and records to agree before quoting
Use this list to agree the build inputs and release records for a similar product. The final set depends on the project.
Design baseline
Released schematic or block diagram, interface table, power states, critical constraints, and revision owner.
Manufacturing release
Gerber or ODB++, stack-up, centroid data, assembly drawings, approved DFM dispositions, and panel assumptions.
Material control
Released BOM revision, manufacturer part numbers, AVL or alternate rules, no-substitute lines, MSL handling, and exception approvals.
Validation record
Test method, acceptance criteria, sample or serial identity, measured-result fields, and disposition. Example fault-injection scope: lift, tilt, collision, sensor disagreement, motor stall, and communication timeout.
Production release
First-article status plus the agreed SPI, AOI, X-ray, ICT, FCT, programming, rework, OQA, labeling, and packing records.
Specify the required record fields, sampling, acceptance limits, approval owners, and retention period in your RFQ. Agree access and disclosure requirements before sharing confidential project files.
Manufacturing requirements to discuss
Scope to confirm for your design
- Multi-axis motor and actuator control.
- Safety-sensor and UI integration.
- Outdoor power-electronics development.
