Highlights in this issue include an interview with Kongsberg Maritime's marine robotics manager Bjorn Gjelstad. Our dossiers detail the UAV Works VALAQ tail-sitter and the Suter Industries TOA 288 naturally aspirated two-stroke boxer engine. The focus articles look at the subjects of cable harnesses and AI systems. Our insight looks at the latest uses of USVs and we have an update from a selection of exhibitors due to be displaying at the delayed AUVSI Xponential event. Our digests feature the MARIN modular AUV and the Vtrus Autonomy Brain Implant, which fits on a variety of vehicle platforms to provide navigation in GNSS-denied environments. And also we explore the operation of the Vitirover UGV, plus we provide details of our newly launched Unmanned Systems Engineering Network.
