AI AGENT ROVER - PARTS & SHOPPING CHECKLIST Reference list, 6 October 2026. Check your existing equipment before buying. Exact installed models are given only where recorded. Sourcing examples are not a verified complete kit. No prices or stock promises. The camera-pan and steering servos are separate items. The AI HAT is not required by the current software. [ ] RC car chassis and drivetrain | Qty: 1 | RC platform | Retain Use the existing rolling chassis, suspension, wheels and body fixings. A different car needs fresh measurements. [ ] Brushed drive motor | Qty: 1 | RC platform | Retain Keep the motor matched to the ESC and battery. Do not buy a brushless replacement for a brushed ESC. [ ] WP-1040 brushed ESC | Qty: 1 | RC platform | Retain Existing controller; verify its exact label, battery compatibility, startup and reverse behaviour. [ ] Steering servo - B7104, marked “3kg” | Qty: 1 | RC platform | Retain / verify Existing car servo, recorded as B7104 in the close-up discussion. Verify the actual label, voltage, spline and linkage; “3kg” is torque shorthand, not current. [ ] 7.2 V car battery | Qty: 1 | RC platform | Retain / verify Confirm chemistry, capacity, condition, connector and ESC compatibility on the actual pack. [ ] Battery charger | Qty: 1 | RC platform | Match to pack Use the charger and settings for the actual battery chemistry and cell count; not the Pi power-bank charger. [ ] Raspberry Pi 5 | Qty: 1 | Compute & vision | Add / reuse RAM capacity was not confirmed in the project record. Choose after checking your intended workload. https://www.raspberrypi.com/products/raspberry-pi-5/ [ ] Pi 5 cooling assembly | Qty: 1 | Compute & vision | Add / reuse The build retains active cooling. Leave airflow and clearance beneath stacked boards. https://www.raspberrypi.com/news/heating-and-cooling-raspberry-pi-5/ [ ] microSD card or supported boot storage | Qty: 1 | Compute & vision | Add / reuse For Raspberry Pi OS and the rover helper; capacity/model to suit your installation. [ ] Raspberry Pi AI Camera - IMX500 | Qty: 1 | Compute & vision | Add Runs object detection on the camera. The separate AI HAT is not required by this project’s current software. https://www.raspberrypi.com/products/ai-camera/ [ ] Pi 5-compatible camera ribbon cable | Qty: 1 | Compute & vision | Check included Match both connectors and allow the camera to pan without pulling or sharply folding the ribbon. https://www.raspberrypi.com/products/ai-camera/ [ ] VL53L1X distance-sensor breakout | Qty: 1 | Compute & vision | Add Confirm the exact breakout and logic compatibility. The linked board is a sourcing example, not a claim about the installed brand. https://www.adafruit.com/product/3967 [ ] Camera-pan servo - MG996R | Qty: 1 | Control & power | Add Positional servo matched to the camera holder. Check actual dimensions, horn spline, travel and current; do not substitute a continuous-rotation version. https://towerpro.com.tw/product/mg996R/ [ ] Matching servo horn and retaining screw | Qty: 1 set | Control & power | Check included Must fit the actual MG996R shaft and camera adapter. It may be included with the servo. [ ] PCA9685 servo/PWM driver board | Qty: 1 | Control & power | Add Camera CH0, steering CH1, ESC command CH2. Check board quality, headers and power rails. Linked Adafruit board is a sourcing example. https://www.adafruit.com/product/815 [ ] 52Pi RPi5 PD Power board - EP-0225 | Qty: 1 | Control & power | Add The power board used in the project. Match the bank’s USB-PD profile and distinguish INPUT from OUTPUT. https://wiki.52pi.com/index.php?title=EP-0225 [ ] USB-C PD power bank | Qty: 1 | Control & power | Select & validate Exact bank model not confirmed. Verify the PD profile needed by the board, sustained load, cable fit and mounted dimensions; battery percentage alone is not enough. [ ] USB-C to USB-C power cables | Qty: 2 | Control & power | Check included Bank → board INPUT and board OUTPUT → Pi. Match power ratings and plug clearance; a suitable board-to-Pi cable may already be included. [ ] UBEC DC/DC converter - 5 V, 3 A | Qty: 1 | Control & power | Add / validate load Project converter: Adafruit 1385 / P1385A as discussed. The 3 A budget is shared by servos; combined peak demand still needs checking. https://www.adafruit.com/category/product/1385 [ ] Known-working Pi mains supply | Qty: 1 | Control & power | Bench tool Useful as a reference supply when isolating portable-power problems. Match the Pi 5 requirements. https://www.raspberrypi.com/products/raspberry-pi-5/ [ ] Battery splitter / power takeoff harness | Qty: 1 | Wiring & connectors | Match & rate Branch the car battery to ESC and UBEC. Match actual connectors and polarity; the project used a Deans/T-style connection with an adapter. [ ] Servo extension leads | Qty: 2 as needed | Wiring & connectors | Measure route For camera and steering. Check plug orientation, wire rating, movement and access before choosing lengths. [ ] ESC signal/ground adapter lead | Qty: 1 | Wiring & connectors | Configure correctly With a separate UBEC powering PCA V+, isolate the ESC red BEC output. Signal and ground retain their distinct roles. [ ] I²C/GPIO jumper wires or secured harness | Qty: 1 set | Wiring & connectors | Match headers Pi to PCA and sensor: power, ground, SDA and SCL. Use suitable retention; the motor current never goes through these jumpers. [ ] Insulation and strain-relief supplies | Qty: 1 set | Wiring & connectors | Workshop supplies Heat-shrink, insulated connectors, cable ties and tie mounts. Keep exposed contacts away from boards and moving parts. [ ] Accessible power isolation | Qty: 1 arrangement | Wiring & connectors | Design for both sources Account for the Pi bank, ESC and servo branch. The ESC switch alone does not cut every branch. [ ] V8 front and rear shells | Qty: 1 each | Prints & fixings | Print Two parts in the V8 download. Use supplied notes, inspect the slice and physically fit-check. assets/rover-v8-print-models.zip [ ] V8 battery frame with five risers | Qty: 1 | Prints & fixings | Print Supports the bank and electronics; included in V8 download. Check battery removal and strap clearance. assets/rover-v8-print-models.zip [ ] V8 electronics plate | Qty: 1 | Prints & fixings | Print Included in V8 download. Check real board fixings, insulation and cable-plug access. assets/rover-v8-print-models.zip [ ] Camera cradle, servo holder and horn adapter | Qty: 1 each | Prints & fixings | Reuse / adapt Separate fitted components, not included in the four-part V8 package.

[ ] Camera screws and nuts - M2 × 6 mm | Qty: 4 each | Prints & fixings | Verify cradle Specified for the camera cradle prototype. Confirm screw engagement and clearance on the actual printed assembly. [ ] Shell screws, washers and board standoffs | Qty: 1 assortment | Prints & fixings | Measure stack V8 notes specify HP0554 No.4 × 12 mm for shell features. Do not use them in small PCB holes. Select washers and standoffs for actual clearance. [ ] Battery retaining straps and pads | Qty: As needed | Prints & fixings | Fit to assembly Secure both packs without pressing a power button or blocking cooling, connectors or removal. [ ] 3D printer or print-service access + filament | Qty: 1 access | Tools & software | Workshop resource P1S was used as the design target; choose material and supports for the part. Files are unsliced. [ ] Digital multimeter, calipers and hand tools | Qty: 1 set | Tools & software | Workshop resource Measure voltage, continuity, mounting dimensions and fastener fit. Include suitable drivers and wire/connector tools. [ ] Raised-wheel test support | Qty: 1 | Tools & software | Workshop resource A stable support that keeps all driven wheels clear while testing steering and ESC behaviour. [ ] Computer, Wi-Fi and software access | Qty: 1 setup | Tools & software | Required Pi OS, camera libraries, rover helper, protected interface and an AI agent able to call tools. Hosting and AI usage may have separate costs.
