Gumstix in MAVs – the 2014 IMAV competition

September 10, 2015 | Uthra Krishnan

Drones are gaining more and more popularity in today’s world and not just for recreational use. The small size and ease of use of micro air vehicles (MAVs) make them ideally suitable in aerial reconnaissance, search and rescue and post-disaster area exploration.

The 2014 competition, held in Delft, the Netherlands invited research teams from countries across the world to compete in a search and rescue mission in a post-disaster village using MAVs. The competition featured obstacles like the following:

  • Map stitching and route planning using aerial photography
  • Navigation in a enclosed two-story building
  • Identification of various objects using computer vision
  • Precision flight navigation

The team from the National University of Singapore won the championship with their quadrotors outfitted with a Gumstix Overo Fire to implement algorithms such as sensor fusion, servo driving, and automatic control. Read more about their work here.

Powerful Handheld Kits Now Support Smart Home, Automotive and Industrial Designs

September 10, 2015 | Uthra Krishnan

New Android/Linux Touchscreen Development Kits

We’re excited to announce two new Pepper Single Board Computers (SBC) based handheld kits. Both boards now support Android™ in addition to Yocto Project Linux®, providing engineers and designers everything needed to prototype with the world’s most popular operating systems.

Gumstix development kits have helped launch some of the world’s coolest products – from phones to drones – and can be found on commercial, university, and hobbyist workbenches in over 45 countries. The additional support for Android opens up our development kits to a wider designer base and a varied list of innovative, Gumstix-prototyped products.

Pepper Development Kit Features

Featuring wireless connectivity provided by Texas Instruments’ (TI) WiLink™ 8 combo-connectivity module (Wi-Fi® + Bluetooth®), the Pepper handheld development kits are ideally suited for smart home, mobile display based, and other industrial and DIY applications.

The Pepper 43C Handheld Development Kit includes the Newhaven 4.3” Capacitive Multi-Touch LCD touchscreen that is ideal to applications requiring quick response time and multi-touch functionality.

Meanwhile, the Pepper 43R Handheld Development Kit includes the Newhaven 4.3” Resistive LCD touchscreen that is ideal for applications such as a handheld gaming console or applications requiring non-capacitive touch. (Read full release here)

We’d love to hear about what you do with our Pepper Handheld Development kits.

Extended Temperature Embedded Components

August 11, 2015 | Uthra Krishnan

Extended temperature requirements are found in a variety of mission critical applications. From military applications and industrial applications to applications in outer space, extended temperature means different things in different circumstances.

For example, embedded computer vendors can support temperature ranges such as 0 °C to +60 °C, -40° to 70°C or -20° to 70°C . Few vendors actually support the full range of -45 °C to +85 °C expected by the more rugged applications.

Why is this important?

Semiconductors can experience a condition called thermal runaway when they operate in very high temperatures. The increase in temperature causes the semiconductor to release energy which further increases the temperature, ending in destructive results. On the opposite side of the spectrum, lower temperatures cause components to run less efficiently, creating errors such as timing errors and changes in values, among others, which ultimately impact computing reliability.
