YEI Technology Division
The Technology Division provides products in robotics, MIDI control, motion control, servo motor control, and show/performance controls. We also provide custom engineered control solutions in these areas.
- YEI 3-Space Sensors
- YEI 3-Space Sensor high-precision Attitude and Heading Reference Systems (AHRS) provide a reliable, high-accuracy, low-cost, small-size solution to movement and orientation challenges. The YEI 3-Space Sensor utilizes on-board processing and filtering algorithms to provide exceptionally accurate attitude and heading information based on the three-axis accelerometer, three-axis gyroscope, and three-axis compass. Orientation can be returned in absolute terms or relative to a designated reference position. The proprietary multi-reference vector mode increases accuracy and greatly reduces and compensates for sensor error. The YEI 3-Space Sensor system also utilizes a dynamic sensor confidence algorithm that ensures optimal accuracy and precision across a wide range of operating conditions.
- ServoCenter™
- ServoCenter™ controllers allow RC servo motors to be easily controlled for uses in robotics, animatronics and other motion control situations, via USB, MIDI, and serial packages, or via on-board programming.
- ServoCenter Downloads
- A library of ServoCenter documentation, including manuals, protocols, schematics, drivers, application notes, source code, DLL programming, ActiveX control, direct serial I/O, firmware updater, control panel utility, sequencer, and other tools.
- SC-BASIC Sequencer / BASIC Interpreter
- SC-BASIC Sequencer / BASIC Interpreter allows ServoCenter 4.1 boards to be programmed to perform various tasks via the use of a simple tokenized BASIC-like scripting language. This feature can be used to implement customer specific logic, I/O, and servo control tasks without the need for a PC or other external command device.
