Precision in motion. Vishay Precision Group, Inc. (VPG) to Introduce Custom Sensing Capabilities for Humanoid Robotics at RoboBusiness 2026

As humanoid robots move from research labs to factories, warehouses, homes and other shared spaces, accurate physical feedback becomes crucial. These machines are designed to mimic human dexterity, balance and decision-making, but require precise, real-time feedback from their environment to perform well in unpredictable situations.

At RoboBusiness, Vishay Precision Group, Inc. (VPG) will showcase its expertise in custom force and torque sensing solutions designed to address the complex mechanical, thermal and electrical challenges of next-generation robotics. VPG provides precision sensing and measurement system solutions that help improve product performance in many industries, making the world safer, smarter and more productive.

Meet us at RoboBusiness.

Advanced vision systems and artificial intelligence handle overall perception and path planning, but force and torque sensing determine how safely and smoothly a humanoid robot interacts with its environment. These robots use powerful actuators, artificial intelligence models, and real-time controls, but still require accurate physical measurements to perform well. Humanoid robots need constant, high-quality data to monitor joint torque, balance, foot pressure, grip force and contact pressure, especially when working closely with people.

Stationary industrial robots work on fixed tracks in controlled spaces, but humanoid robots must move through changing environments, handle unpredictable loads, and handle many points of contact. They need force sensing solutions that go beyond standard hardware. These sensors should be integrated into the robot’s structure from the beginning, transforming basic mechanical parts into intelligent, responsive systems.

Many engineering teams start with off-the-shelf components for rapid prototyping, but encounter major integration problems as designs develop. Off-the-shelf sensors are often too large for robots’ small limbs, and their shapes or mounting needs can force engineers to redesign parts just to fit the sensor. These catalog sensors also have measuring ranges that are too wide, which reduces the accuracy of the signal. They often lack multi-axis measurements and require bulky external electronics that add to the size, wiring and electrical noise of the system. Additionally, standard parts lack the thermal and environmental adjustments needed for the temperature changes and vibrations found in compact robotic joints.

VPG designs custom force and torque sensors integrated directly into the robot structure. These sensors use precise strain gauge technology attached directly to mechanical parts, so even the smallest deformations under load create measurable changes in electrical resistance. Using a Wheatstone bridge circuit, these changes are transformed into accurate analog or digital signals. The sensors can measure one or more directions simultaneously, providing detailed tactile feedback, joint torque data, and multi-axis information from wrists or feet, all with the precision needed for real-time control.

“At VPG, we focus on delivering precision sensing solutions exactly where they are needed most: at key points of performance, safety and control in today’s advanced intelligent systems,” said Ron Zukerman, Director of Innovation at Vishay Precision Group, Inc. “With six decades of aerospace-grade force sensing experience, we connect experimental mechanics with intelligent system integration, helping engineers test, validate and add sensors with exceptional accuracy and reliability.”

At RoboBusiness, VPG highlights custom strain gauge-based solutions that address four key performance areas in humanoid robot design:

Miniature tactile force sensors they are made for very small, low-capacity uses such as humanoid fingertips, knuckles, and joint mechanisms. They use flexible designs and are extremely lightweight, so they do not affect the movement of the robot. They can measure both tension and compression and respond quickly, with natural frequencies at kHz levels. This high-speed feedback is essential for delicate grip, detailed manipulation and precise tactile control.

Multi-axis force sensors they are built for complex joints such as humanoid torsos, shoulders and wrists. They use sensitive strain gauge designs, crosstalk compensation, and strong thermal stability to measure multiple directions simultaneously in a compact design. This accurate data is critical for real-time balance, coordinated movement, walking and safe human interaction.

Joint torque sensors they are made to manage loads in moving joints such as shoulders, elbows and knees. Custom-fit to each joint, they measure torque directly and in real time, without adding additional weight or complexity. By obtaining accurate torque data from inside the actuator, VPG helps robots move smoothly, respond quickly, and keep actuators lightweight.

Circuit sensors with force feedback they are designed to provide real-time feedback directly to the robot’s control system. They provide fast and stable data even when loads change rapidly, allowing humanoid robots to gently grasp objects, adjust their resistance, recognize gestures and work safely with people in factories or healthcare facilities.

To help robotics OEMs move from concept to full-scale production, VPG offers comprehensive technical support. VPG manages the entire process internally, from requirements definition and deformation optimization with FEA, to prototype testing, thermal adjustments, design changes, manufacturing tooling and final quality checks. Depending on the project phase, VPG collaborates with engineering teams through flexible partnerships, including full development, co-development or production according to customer specifications.

At RoboBusiness, robotics engineers, CTOs, and R&D leaders can meet with the VPG team to learn about custom sensor integration, bending designs, and technical resources.
