Exploded parts and connection routing.

The numbers match the printed-parts table. Lettered hardware groups show the electronics and purchased parts. Colored lanes show what connects mechanically, electrically, and by USB/data.

Mechanical: bolts, heat inserts, slots, standoffs

Power: battery, fuse, bus, bucks, drivers

Data: RP5 USB, Wi-Fi, LoRa, touchscreen

Servo: claw boards to claw and light servos

Lighting: nine protected RGB ground-effect modules

Wet-use: glands, drip loops, covers, splash guards

The map uses numbered callouts to keep the illustration readable. Match each number to the printed-parts inventory below for the exact STL file, dimensions, and connection point.

Connection order

Build from the frame outward.

The order below keeps the heavy parts low, the serviceable electronics accessible, and the claw/lighting harnesses away from moving joints.

Step 1

Frame and tray

Parts 1-7 bolt together as the sealed chassis: skid plate, battery tray, side rails, front/rear crossmembers, and electronics deck.

Step 2

Motors and driver covers

Parts 13-14 protect the IBT-2 boards and motor corners. Four direct-drive motors fasten at the rail/crossmember corners.

Step 3

Electronics bay

Parts 8-12 install on the electronics deck. The RP5, relay HAT, buck converters, fuse bus, and LoRa USB bridge stay inside the sealed bay.

Step 4

Top-shoulder claws

Parts 15-25 build the shoulder bridge, round shoulder mounts, left/right claw bases, wrists, palms, fingers, link bars, and gear covers.

Step 5

Screen and hood

Parts 27-31 mount the 7 inch USB touchscreen above the electronics bay with left/right uprights, top bar, bezel, and rain hood.

Step 6

Ground-effect LEDs

Nine RGB LED star modules mount under the chassis. Side servos sit in parts 26 and tilt the light rails from spare claw-board channels.

Step 7

USB and radio

RP5 USB goes to left claw board, right claw board, 7 inch touchscreen, and LoRa bridge or powered hub. Pi Wi-Fi remains available for setup/API.

Step 8

Remote transmitter

Parts 36-38 house the Raspberry Pi Zero 2 W, Pico Voice, and remote LoRa bulkhead. No Pro Mini and no nRF24L01+ are used.

Real component photos

These photos are the real part references already saved in the GAR-BOT project.

H1 RP5 + Relay HAT

Bolts inside electronics bay 8 and receives 5.1V buck power.

H3 IBT-2 motor drivers

Four covered drivers connect RP5 GPIO to the four 24V motors.

H5 claw boards

Left and right USB servo boards drive the claws and side light servos.

H12 LED modules x9

Sealed underbody ground-effect modules in three banks.
