Unmanned Systems Technology 036 February/March 2021
- Intro - Closing a project doesn’t mean it was a failure – it should be seen as a learning process for engineers of the future
- Platform one: Mission-critical info - New localisation software cuts power requirements, sensor helps multi-rotor UAVs keep flying if a motor fails, module unveiled that shuts off vehicle electrical systems in microseconds, and more
- In conversation: Geoff Cathcart - Orbital UAV’s CTO explains how a progressive early education system influenced how he approaches problem-solving
- Dossier: Saab Sabertooth - Acting as a type of permanent janitor for deep-sea infrastructure, this craft blurs the boundaries between an ROV and a AUV
- Focus: IMUs - As accelerometer and gyro technologies advance, distinctions between them and what they can do are becoming less important
- Insight: UUVs - If creature diversity is good for underwater ecosystems, then as engineers have realised, it’s good for UUV designs
- Report: Oceanology International - The 2020 edition of this show had to be held virtually, but thanks to AI it still drew a lot of companies with plenty to announce
- Digest: Flybotix ASIO - While not the first UAV to have a protective cage, this bi-copter does not need GNSS for navigation, which with its unusually long endurance makes it ideal for inspecting industrial assets
- Dossier: Hirth 3507-01M - We chart the development of Hirth’s 3507 inline two-stroke workhorse, culminating in this latest version, which has been modified primarily to run on heavy fuels
- In operation: Aurrigo shuttle - Yet another event affected by the Covid pandemic was the 2020 Wales Open golf tournament, but it still went ahead thanks to the deployment of this self-driving vehicle
- Focus: Additive manufacturing - Unmanned systems designers take note – AM technology is becoming faster at producing components while developing the ability to make them from combinations of materials
- Digest: Zepher Flight Labs Z1 - Hydrogen fuel cells make this VTOL-transitioning UAV quiet and give it long endurance, making it suitable for a range of military as well as commercial applications
- PS: AriAscend UAV ID system - UAVs will soon have to be fitted with technology that broadcasts their identity and location. We look at one system for enabling that
