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 was 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. Realbotix last listed it from ninety-five thousand dollars, plus 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.
Off Realbotix's site
As of October 30, 2026, Realbotix's site no longer lists Melody or the M-Series. The old robots and Melody pages return "not found" errors, and the pricing page and online store carry only the new Echo line, launched on October 26 with Aria and three other personas, none of them Melody. The last archived copy of the old lineup, from September 20, 2026, still showed the M-Series from $95,000. Realbotix hasn't announced an end to the M-Series, so we haven't marked it discontinued, but confirm pricing and availability with Realbotix before counting on one. The full-body Echo lists the same 39 degrees of freedom Realbotix quoted for the M-Series at IFA 2025, at $59,950, though the company hasn't said whether it is the same body.
Our verdict
The case for
- Far more portable than Aria
- An openly hackable AI platform for builders
- Shares Aria's expressive 17-motor head
The case against
- A six-figure object as last listed
- Does not walk
- A CES headline calling it "walks like a human" was misleading marketing
- No longer on Realbotix's site, and the new Echo line has no Melody persona
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
The paper trail
Dated milestones — announcements, prices, promised ship windows — as they were made. We add to this record; we don't rewrite it.
M-Series dropped from Realbotix's site
realbotix.com/robots and /melody now return 404, and realbotix.com/pricing lists only the Echo line launched Oct 26, which has no Melody persona. The last archived lineup (Sept 20, 2026) showed the M-Series from $95K plus a $199.99/mo plan. No discontinuation notice found.
39 degrees of freedom and an enhanced eye-camera vision system for real-time recognition and gaze awareness.
Price reported around $150,000
Launch coverage put the modular Melody near $150,000; the M-Series has since been listed from $95,000 (see above).
