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

The ServoCenter™ family of embedded servo controllers allows RC servo motor control from any USB, serial RS232, MIDI-capable device.  ServoCenter is also available in DIP and TQFP chip packages.  The ServoCenter 4.1 Sequencer allows complex tasks to be programmed via a script sequencer in addition to other programming options that are standard in the ServoCenter products.

ServoCenter allows amazing and unsurpassed control of the seek position and seek speed of up to sixteen connected servos -- independently and simultaneously, with simple, logical commands.  Up to 16 (32 for MIDI version) ServoCenters may be chained together to control up to 256 RC servos (512 for MIDI version), with completely independent movement, from only one serial, USB, or MIDI port!  Independent control allows you to  move one servo to a position slowly, while another is moving to a different position at a faster speed, and group moves allow you to synchronize multiple servos easily. ServoCenter controllers are especially useful for applications such as robotics, animatronics, motion control, automation, retail displays, and other areas where independent and coordinated fluid servo motion is desired. ServoCenter can be programmed using a simple raw packet protocol or using the included ActiveX control or Win32 DLL. Sample programs illustrating all programming methods are included in the documentation and examples CD. The ServoCenter Command Protocol allows complex servo movement commands to be issued by constructing and transmitting simple command packets.
