Build Profile

Sealed body, serviceable electronics, real claw mechanics.

GAR-BOT keeps the Raspberry Pi 5, relay HAT, Wi-Fi/LoRa radio hardware, buck converters, and motor drivers behind covers, glands, and gasketed access panels.

The drivetrain is four-motor direct drive: each 24V gear motor drives its own wheel. Chain, sprockets, and exposed reductions are not part of the active wet-use design.

The front hardware uses two matching articulated claws based on the real curved gripper reference, with gear guards, forearm wire covers, and protected controller boards.

Robot Systems

Designed around the parts in the GAR-BOT package.

Power

24V battery bus for motors, 5.1V high-current buck for RP5, and a separate servo buck for the claws.

Control

Raspberry Pi 5 local agent, four IBT-2 drivers, Wi-Fi for setup/API, LoRa radio path, and Pico Voice on the 40-pin header.

Motion

Four XD-60GA775-style 24V gear motors direct-drive the wheels, with splash shields and protected wiring routes.

Claws

Left and right front claws, each with its own Keyestudio-style controller board and six servo channels.

Physical Reference

Two claws, covered wiring, protected joints.

The claw system follows the photographed servo gripper: curved fingers, gear-linked jaws, parallel links, round shoulder mounts, and protected wrist servo sections.

Remote Transmitter

RP Zero 2 W plus Pico Voice replaces the Pro Mini.

The handheld transmitter uses Raspberry Pi Zero 2 W Wi-Fi for setup/testing, Pico Voice, and a LoRa transmitter path for long-range control. The older Pro Mini board is reference only.
