  • Improved impact buffering for contact-rich applications
  • Dual-feedback architecture support for force estimation

Typical Applications

  • Rehabilitation and assistive robotics
  • Service robots with physical human interaction
  • Force-sensitive manipulation and validation platforms

Engineering Focus

  • Spring stiffness selection versus control bandwidth
  • Torque estimation accuracy and sensor calibration route
  • Safety and controllability in collision scenarios

Key Evaluation Matrix

MetricTypical RangeWhy It Matters
Stiffness option window100-500 Nm/rad (project dependent)Defines system compliance and closed-loop force behavior.
Torque sensing strategyDual encoder + deflection estimationSupports predictable impedance and force-control performance.
Continuous torque classApplication dependentEnsures compatibility with mission duty and safety envelope.

Compliance and Trade Guidance

CE, RoHS, and REACH documentation support is available by project scope. HS classification should be treated as reference guidance only and must be confirmed by importer/broker based on destination rules and final product configuration.

  • Confirm required compliance document list before sample planning.
  • Include destination market and declaration scope in your RFQ message.
  • Review detailed guidance in Resources / Compliance.

RFQ Checklist

  1. Target force/torque range and control mode
  2. Desired stiffness window and compliance behavior
  3. Encoder/sensor architecture requirements
  4. Validation test plan and pass/fail thresholds

Risk Controls

  • Unsafe or unstable interaction behavior: Run staged bench validation for stiffness, impact, and control response.
  • Inconsistent torque estimation across lots: Define calibration records and acceptance checks before pilot release.

Buyer FAQ

Can spring stiffness be customized for our payload target?

Yes. Stiffness and control-side assumptions can be co-defined for sample validation.

Do you support force-control-focused integration discussions before PO?

Yes. We can align architecture and validation checkpoints during RFQ review.
