Controlledcontact

Controlledcontact is a framework for regulating physical contact between humans and machines to ensure safety, consent, and effective interaction. It is used in robotics, prosthetics, rehabilitation devices, and medical technologies where touch or contact is integral to function. The term encompasses design principles, control strategies, and safety mechanisms that govern when and how contact occurs, how much force or restraint is allowed, and how the system responds to changes in human intent or motion.

Core components of controlledcontact include explicit consent modalities, safe-by-design hardware and software, and systematic risk assessment. Technical implementations often rely on impedance or admittance control to create compliant interaction, along with force/torque limits, power-and-force limiting, and hand-guiding capabilities. Safety interlocks and monitored-stop modes provide immediate disengagement if contact becomes unsafe. Sensor suites—such as force and torque sensors, tactile arrays, and vision systems—support reliable detection of contact state, while data logging and telemetry support accountability and post-hoc analysis.

Controlledcontact practices align with broader human-robot collaboration standards and device safety frameworks, including ISO 10218 and ISO/TS 15066, and influence medication and clinical device guidelines in contexts where touch is involved. Applications span surgical assist devices, rehabilitation exoskeletons, smart prosthetics, and assistive robots for elder or disability care. Ongoing challenges include latency, sensor reliability, user variability, privacy considerations, and balancing intuitive guidance with user autonomy. Research in this area focuses on adaptive contact policies, user modeling, and multimodal consent verification to enhance safety, trust, and acceptance.
