Sony's aibo robot set the benchmark for autonomous home robotics—packing SLAM mapping cameras, actuators, and cloud AI into a floor-roaming robotic puppy. Yet most people admiring Japanese robotics neither need a multi-thousand-dollar floor robot nor want indoor cameras mapping their apartment. That gap is why compact, tactile companions like Yukai Engineering's Mirumi exist.
Disclosure & scope: Published by mirumirobot.com (where Mirumi Ivory, Pink, and Gray retail for $88.00). Specifications cite Yukai Engineering's published US FAQ and reference docs (checked October 2026).
1. Sony aibo vs. Yukai Engineering Mirumi
| Dimension | Sony aibo (ERS-1000) | Yukai Engineering Mirumi |
|---|---|---|
| Form & weight | Molded hard-shell quadruped (~2.2 kg) walking on floors | Custom Japanese plush charm robot (~155 g; 100 × 110 × 140 mm per US Gray spec) |
| AI, cameras & cloud | Cameras, facial recognition, cloud AI plan, and smartphone app | No AI, no language recognition, no camera, no app or subscription (US FAQ) |
| How you interact | Voice commands, app tricks, autonomous room roaming | Head-petting touch sensor and sound/voice response with tuned head turns and pauses |
| Portability | Home floor bound | Wraps around ~10–15 mm bag straps (US FAQ); USB-C rechargeable |
2. Two Opposite Ends of Japanese Companion Robotics
Where aibo aims to simulate an autonomous pet walking through a house, Mirumi focuses on a single intimate moment: reaching toward your bag handle or desk edge, patting soft fur, and watching a curious head turn. Compare Mirumi Robot Ivory, Mirumi Robot Pink, and Mirumi Robot Gray.
