Modular accessories for off-the-shelf robots

Robot addons

Each addon is a small, focused module — a charging dock, a payload tray, a behavioral companion — designed to bolt onto an existing robot rather than replace it. Real BOMs from AliExpress, parametric OpenSCAD CAD, install steps, and compatibility list.

Utility(1)

Universal magnetic charging dock for quadruped robots

Wall-mounted dock with magnetic alignment, 5A USB-C PD output and a contact pad that fits Unitree Go2, Spot and Anymal. The robot drives onto the pad and charges without a tether.

Companion(1)

Pet companion module for quadruped robots

A removable rear-mount module that turns a quadruped robot into a temporary mate-stand-in for pets that have residual mating instinct after spaying/neutering. Anatomical silicone insert, body-temperature heating pad, dog-appeasing pheromone reservoir, self-cleaning cycle when docked.

Clip-on motorized tail for companion robots

Loona, AIBO, Pari and Vector look almost-alive but tail-less, which kills the uncanny gap. This addon clips a 14cm articulated silicone tail onto the rear of the robot, with three servos for wag/curl/posture and an open API that lets the host robot control it as an emotional output channel.

Cat saddle for Roomba and other robot vacuums

A grip-padded ergonomic saddle that bolts onto the top of a Roomba, Roborock or Dreame robot vacuum. Cats already ride these — the saddle gives them a proper seat with claw-friendly fabric, a low rim and an emergency 'meow alert' button on the rim that pages the owner if the cat panics.

Drop a one-liner ("a heated payload tray for cold deployments", "a thermal camera mount for Anymal") and the AI will spec it out.
