Robotic surgery is an operation performed with the help of a robotic system instead of a surgeon’s hands alone. In almost every case today, a human surgeon is still directing the robot in real time — the machine translates the surgeon’s movements into smaller, steadier motions inside the patient. A smaller number of experimental systems can now complete parts of an operation on their own, guided by AI trained on video of past surgeries.
What robotic surgery actually is
The most common form is teleoperated, minimally invasive surgery. The best-known example is the da Vinci Surgical System, made by Intuitive Surgical: the surgeon sits at a console a few feet from the operating table, looking through a magnified 3D camera view, while robotic arms holding miniaturized instruments mirror the surgeon’s hand movements through small incisions. First cleared by US regulators in 2000, da Vinci systems have now been used in more than 10 million procedures worldwide, mostly for prostate, gynecological, cardiac and abdominal surgery.
The key point non-specialists often get wrong: the robot does not decide anything. It is a very precise puppet. It scales down tremor, filters out hand shake, and lets a surgeon reach angles a human wrist can’t, but every cut is still a human choice, executed a moment later by the machine.
From remote control to real autonomy
That is starting to change, in two directions at once.
The first is distance, not decision-making. In July 2026, researchers at UC San Diego published results in Nature showing that general-purpose humanoid robots — off-the-shelf Unitree G1 units nicknamed “Surgie,” standing about five feet tall — could be fitted with surgical-instrument adapters and teleoperated by a remote surgeon to complete a live gallbladder removal on a large animal. The robots are a fraction of the size, weight and cost of a fixed da Vinci cart, which matters because it suggests general-purpose robots, not just dedicated surgical hardware, could eventually bring remote surgical expertise to places that can’t afford or house a full robotic suite.
The second direction is genuine autonomy. In 2022, Johns Hopkins’ Smart Tissue Autonomous Robot (STAR) became the first system to complete a laparoscopic procedure — reconnecting two ends of pig intestine — without a human moving the instruments, guided instead by 3D imaging and machine-learning models trained to track the tissue. A follow-on system built on the same kind of architecture used in modern chatbots has since performed complete simulated gallbladder removals — a 17-step procedure — with no human input, adapting in real time to unexpected obstructions like blood.
These autonomous systems are still confined to research labs and animal or simulated tissue, not live patients. Robotic surgery today spans a spectrum: fully human-controlled (da Vinci), human-controlled from a distance (teleoperated humanoids), and, in early research, partially self-directed (STAR and similar systems).
Why it matters
The practical case for robotic surgery is access and consistency. Many regions have too few trained surgeons for procedures like gallbladder removal or hernia repair, and a specialized robotic cart costs well over a million dollars, putting it out of reach for smaller or rural hospitals. Cheaper, more portable teleoperated systems could let a specialist in one city operate on a patient in another. Autonomous systems, if they eventually prove safe on live patients, could reduce the variability between a routine procedure done by an experienced surgeon and one done by someone earlier in their training — the Johns Hopkins team reported its autonomous suturing outperformed human surgeons doing the identical task on the same tissue.
Why it matters for Georgia
Robotic surgery is not a hypothetical for Georgia. Da Vinci systems are already in clinical use in Tbilisi — the Guram Karazanashvili Robotic Center specializes in robotic urological procedures, and Acibadem’s Tbilisi hospital offers robotic-assisted colorectal, gynecological and head-and-neck surgery. As teleoperated and autonomous systems mature, the same argument that applies to rural US hospitals applies here: lower-cost robotic platforms could extend specialist-level surgical care beyond the capital.

FAQ
Does a robot ever operate completely on its own on a real patient today? No. Fully autonomous systems like STAR have only operated on animals or simulated tissue in research settings; every robotic surgery performed on a human patient today is still directed by a surgeon, either at the table or remotely.
Is robotic surgery safer than traditional surgery? For many procedures it offers less blood loss, smaller incisions and faster recovery, but large studies have not consistently shown it beats standard laparoscopic surgery on every outcome — the benefit varies by procedure and surgeon experience.
What’s the difference between “robotic” and “robot-assisted” surgery? They’re generally used interchangeably; both describe a robotic system extending a surgeon’s hands rather than replacing their judgment.
