It explains that, “engineering employers should encourage their staff to share their skills and knowledge.” The use of high precision gears is often critical in robotics, aeronautics and aerospace applications. Here, lightweight and compact gears, featuring zero backlash and high reduction ratios, improve the efficiency and cost effectiveness of development. However, teaching it is not always mandatory on relevant degree syllabuses. For instance, The Guardian recently highlighted the importance of gearing in the field of robotics, featuring comment from Graham Mackrell, managing director of Harmonic Drive UK. The industry has already taken the manufacturing world by storm and is now diversifying for future use in public and home applications. “The most direct way of addressing this issue is by directly talking to and informing young people faceto face,” explained Graham Mackrell, managing director of Harmonic Drive UK. “To make sure that the engineers of tomorrow are equipped with the knowledge and expertise required to face these new challenges, we’re currently developing material to be delivered during a series of guest lectures and campus visits. “If any universities, lecturers or organisers are interested in enhancing the delivery of their course modules with the latest developments in the robotics, aeronautics or aerospace industry, we urge them to get in touch.” Harmonic Drive specialises in high precision gears and servo actuators for mission critical industries including offshore oil and gas, aerospace, defence, industrial automation and defence applications.

Harmonic Drive http://harmonicdrive.de/en Programmable magnetic sensor IC in kit Melexis is now supporting its MLX90393 programmable magnetic sensor IC with an evaluation board (EVB), only 30 by 30mm, which gives engineers a platform for testing a wide variety of human machine interfaces. Applications go all the way from relatively simple slide, push/pull and linear swipe switches right through to more complex 3D sensing systems, such as joysticks or rotary knobs with push functions included. Relying on Melexis’ proprietary Triaxis® technology, the 16-bit resolution MLX90393 sensor IC on each EVB has the capacity to deliver a digital output proportional to the detected magnetic flux density along 3 perpendicular axes (X, Y and Z). In addition, there is also provision for thermal measurement. The IC acts like a building block for position sensing systems in a broad spectrum of applications. It presents engineers with a wide array of configurable parameters, allowing them to optimize their system for either high speed measurement, elevated signal integrity or low power consumption. Both SPI and I2C interfaces are featured on the EVB, making it easy to integrate with an external microcontroller. There is also a pad incorporated onto the board for the connection of a decoupling capacitor if required, as well as pads for optional pull-up and pulldown resistors for I2C addressing and bus line supply. An operational temperature range spanning from -20°C to +85°C is supported. The EVB is supplied with a MLX90393 IC soldered directly to the PCB, along with 3 extra ICs to accompany it. A QR code link printed on the underside of the board permits immediate access to all the relevant documentation available on the Melexis website.
