SENSORS: With versions weighing only 11.5 gm, MicroStrain® Inc.’s 3DM-GX3TM-25 AHRS is the first of the 3DM-GX3 family of miniature inertial systems to be released into the market. It will enable the development of the next generation of wearable tracking devices and smaller, lighter unmanned vehicles and robots. The 3DM-GX3-25 AHRS combines 12 sensors - triaxial accelerometers, gyroscopes and magnetometers with three embedded temperature sensors and an onboard microprocessor running a sophisticated sensor fusion algorithm to provide static and dynamic orientation and inertial measurements. Improved performance under vibration is achieved by over sampling the sensors at 30 KHz, digitally filtering and performing coning and sculling integrals at 1 KHz and outputting deltaAngle and deltaVelocity. Each 3DM-GX3-25 AHRS is individually calibrated to compensate for gyro-G-sensitivity and sensor misalignment. Full temperature compensation for bias and sensitivity of all nine sensors ensures performance over the full operating range of the sensor. A new mounting system provides precision alignment of the sensor. The 3DM-GX3-25 AHRS is supplied with routines that enable the user to carry out hard and soft iron field calibrations, where appropriate. Units are available with USB 2.0, RS232 and TTL serial interfaces.
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
Clean diesel continues to be the fuel of choice for transportation authorities in major U S cities, in spite of competitive options aimed at reducing emissions, according to a nonprofit agency that represents diesel engine and equipment manufacturers.
A panel at this year's Consumer Electronics Show in Las Vegas discussing upcoming FAA regulations for non-military drones brought out many of the issues that concern both industry and federal regulators.
