Implementation of SSI Interface

Synchronous Serial Interface (SSI) is a widely used serial interface standard for industrial applications especially, rotary encoders. It is a point-to-point connection from a master (e.g. PLC, microcontroller or other control systems) to a slave (e.g. the rotary encoder).

MEMS Inclinometer Specifications

Inclinometers, also called tilt sensors, clinometers, or slope sensors, are designed to measure the angle of an object with respect to the force of gravity. These tilt or level meters determine the pitch and/or roll angle and output these values via the appropriate electrical interface.

Accuracy, Resolution and Repeatability

There are several key terms that are critical to specifying the optimal position sensor for a given application. This application note defines these key terms and how they relate to the sensor’s role in the overall system performance. It is important to consider that precision is very much a system issue and can be dominated by mechanical errors such as eccentricity. This paper discusses the most significant mechanical error for rotary applications (eccentricity) and presents eccentricity tolerant position sensor solutions.

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.
