NASA- Robonaut 2

Robonaut 2 (R2) is a state-of-the-art, highly dexterous anthropomorphic robot. The robot is designed to work with humans and has the ability to use the same workspace and tools.

The robot joints incorporate dual encoders for position and torque feedback while performing in a dynamic application, vibration, shocks, and wide temperature range.

Inductosyn: End of an Era, New Opportunities or Both?

Recently, obtaining the Inductosyn and components for maintenance has become more difficult. For decades the Inductosyn from Farrand Controls / Ruhle Companies sat near the top of the rotary sensor hierarchy. Providing sub 2 arcsec (0.5 mdeg) accuracies, it combined the robustness of a resolver with the performance of the best optical encoders. Despite its shortcomings, it found plenty of customers, from airborne infrared and radar systems, to telescopes, satellite communication antennae (SATCOM), machine tooling and low-pressure vacuum chambers.

Inductosyn vs Modern Rotary Encoders

An Inductosyn is type of inductive position sensing device from Farrand Controls/ Ruhle Companies. Inductosyns work using the same basic physics as a transformer using planner arrays of inductive windings.

LVR, a Temperature Independent Alternative to LVDT’s in Harsh Environments

The LVR sensor (Linear Variable Resonance), is a new patented non-contact linear position sensor that is a potential replacement for the LVDT sensors in harsh environments.
