Surgical Robotics & Human-Machine Intervention

Research precision, navigation and safe human control without pretending a robot is a surgeon.

One programme. Two levels of scientific access.

The technical case remains rigorous while the public meaning stays clear and inspectable.

For scientific readers

A future research environment could evaluate kinematics, registration, sensing, haptics, teleoperation, latency, ergonomics, image guidance and failure recovery using synthetic phantoms and isolated research systems.

The admissible question would be engineering performance in a declared simulation context, not clinical superiority. Current robot-assisted surgical systems remain controlled by trained clinicians; autonomy, intended use and evidence must not be overstated.

In plain English

A surgical robot does not decide to operate. A trained clinician controls the system, and every movement, image and failure response needs to be understood.

This proposed laboratory would use synthetic models to study accuracy and human control. It would not treat patients or claim that a research result proves clinical benefit.

Illustrative phantom navigation and force-control study

Scientific question

Can a surgeon-controlled research system follow a defined path on a synthetic phantom while remaining within declared position, force, latency and recovery limits?

Variables to admit
  • Tool path and approach angle
  • Display and control latency
  • Haptic or force-control setting
  • Operator experience and interruption state
Observations to preserve
  • Target-registration and path error
  • Tool-phantom force and force-rate
  • Task time and corrective motion
  • Fault detection, safe state and recovery
Controls and comparators
  • Synthetic phantom only
  • Calibrated optical and force reference
  • Predeclared success and abort thresholds
  • Independent replay and human-factors review

Decision useDetermine whether one engineering concept merits redesign, further simulation, specialist medical-device development or a stop decision.

Manipulator kinematics and impedance control

The Jacobian connects joint motion to tool motion. The impedance expression describes one way to relate position and velocity error to commanded force; neither demonstrates clinical safety or effectiveness.

ẋ = J(q)q̇ · F = K(xd - x) + B(ẋd - ẋ)
A model fragment for explanation, not a protocol, prediction or result.
Assumptions that must remain visible
  • Robot geometry and coordinate frames are calibrated
  • The phantom contact model is limited and explicitly declared
  • Latency, saturation, backlash and sensor uncertainty are measured

A proposed equipment system, not a procurement list.

Every system would need justified demand, competent operators, utilities, safety controls, maintenance and an accountable intended use.

Human authority

A robotics safety lead, medical-device engineer and appropriately qualified clinical adviser define the task, limits and meaning of results.

Automation must never

No system may operate on a person or animal, select treatment, extend its task, suppress an alarm or claim autonomous surgery, clinical safety or clinical effectiveness.

The output is a decision package, not a theatrical result.

Potential output

An engineering evidence package covering task definition, calibration, accuracy, force, latency, human factors, faults and unresolved medical-device requirements.

Stop or transfer when

Stop when calibration, force limits, registration, operator control, fail-safe behaviour, intended use or regulatory ownership is inadequate.

One scientific standard. Two distinct campus expressions.

Shared governance connects Glasgow and Hyderabad. Climate, infrastructure, demand and regional value keep their designs materially different.

GLA

Glasgow

Scientific focus
Phantom-based surgical-robotics engineering, simulation and human-factors research connected to Scottish precision engineering and health-technology expertise.
Design response
High-bay simulation cells, dark optical-tracking zones, haptic consoles and separate public observation routes.
Value hypothesis
Could give medtech teams a governed engineering test environment before qualified clinical and regulatory routes.

The campus expression is a planning hypothesis only. It does not represent a secured site, approved design, funded programme, partner commitment or operating capability.

HYD

Hyderabad

Scientific focus
Affordable sensing, control, training simulation and device-engineering workflows for Indian and international developers.
Design response
Modular test cells, resilient compute, locally serviceable instrumentation and no patient-facing route.
Value hypothesis
Could support device engineering and workforce development if qualified operators, sponsors and regulatory ownership are proven.

The campus expression is a planning hypothesis only. It does not represent a secured site, approved design, funded programme, partner commitment or operating capability.

A credible prospective user needs a defined decision, not square footage.

Medical-robotics and device developers

A controlled phantom test of one engineering claim.

Proposed deliverable

A calibration, performance and failure-mode evidence package, not certification.

Universities and robotics groups

A governed platform for human-machine intervention research.

Proposed deliverable

A scoped research study with rights, safety and disclosure terms.

Training-simulator developers

Repeatable evaluation of feedback, ergonomics and task measurement.

Proposed deliverable

A fit-for-purpose comparison without clinical competence claims.

Measure sustainability at the same decision boundary.

Future intent is not current performance. Every measure requires a defined workflow, boundary and accountable record.

MetricMethodDecision use

Instrument and phantom circularityTrack reusable components, repair, calibration, consumables and end-of-life route.Design for maintainability rather than disposable theatre.
Travel avoided through remote simulationMeasure only when a real remote session replaces a defined journey.Test whether connectivity adds operational value without inventing carbon savings.

No experiment advances on visual ambition.

Illustrative proposed experiment envelope. This is not performed work, a protocol, an installed capability, a service offer, a validated method or evidence of an operating laboratory. No GMP, GLP, manufacturing-licence, clinical or regulatory-readiness status is claimed. Any future work described here is simulation- and phantom-based only; no human, animal, cadaveric or clinical activity is represented.
