Photos flatter; motion is where realism is won or lost.
Melody is Aria's pragmatic sibling, productised as Realbotix's M-Series. It shares the expressive 17-motor silicone head but answers two different desires: portability and openness. The body uses smoother Dynamixel P-Series servos, disassembles into a carry case for air travel, and watches the world through micro-cameras set in the eyes for real eye contact and object recognition.
The bigger difference is philosophical. Melody is sold as an open platform: run Realbotix's own AI, or wire in your own — ChatGPT or a local model — and build the personality you want. For developers, artists, and tinkerers, that openness is the appeal.
The caveats are Aria's caveats. It still costs ninety-five thousand dollars and up, still carries the monthly AI subscription, and — despite one breathless CES headline — it does not walk; it's expressive from the waist up and stationary below. Think of Melody as the companion for people who want to get under the hood, not just sit across from it.
Our verdict
The case for
- Far more portable than Aria

- A CES headline calling it "walks like a human" was misleading marketing
What it can do
- Expressive conversation with eye contact and object recognition
- Modular, open platform — run proprietary or third-party AI
- Packs into a case and reassembles on the road
