Stella Juva, a solar vehicle built by Eindhoven University students, functions as a mobile clinic that powers its own medical equipment using sunlight in remote areas.

'I ran because I knew I would die': Russian drones target medics in Ukraine Inna Lytvynenko always puts on her bright orange body armour when she's out on an emergency call. Last June, the paramedic was sent out in Kherson to treat a woman injured in a Russian drone attack, when an FPV drone smashed into her ambulance. Seconds later, she heard a buzzing sound in the sky. Another drone was flying straight towards her, fast. I grabbed my trauma bag and started running, she recalls.

Simulation plays a key role in scaling robot learning and validating policies, but constructing simulations remains a labor-intensive process. This paper introduces ReGen, a generative simulation framework that automates simulation design via inverse design. Given a robot's behavior -- such as a motion trajectory or an objective function -- and its textual description, ReGen infers plausible scenarios and environments that could have caused the behavior. ReGen leverages large language models to synthesize scenarios by expanding a directed graph that encodes cause-and-effect relationships, relevant entities, and their properties. This structured graph is then translated into a symbolic program, which configures and executes a robot simulation environment. Our framework supports (i) augmenting simulations based on ego-agent behaviors, (ii) controllable, counterfactual scenario generation, (iii) reasoning about agent cognition and mental states, and (iv) reasoning with distinct sensing modalities, such as braking due to faulty GPS signals. We demonstrate ReGen in autonomous driving and robot manipulation tasks, generating more diverse, complex simulated environments compared to existing simulations with high success rates, and enabling controllable generation for corner cases. This approach enhances the validation of robot policies and supports data or simulation augmentation, advancing scalable robot learning for improved generalization and robustness.

While simulators exist for vehicular IoT nodes communicating with the Cloud through Edge nodes in a fully-simulated osmotic architecture, they often lack support for dynamic agent planning and optimisation to minimise vehicular battery consumption while ensuring fair communication times. Addressing these challenges requires extending current simulator architectures with AI algorithms for both traffic prediction and dynamic agent planning. This paper presents an extension of SimulatorOrchestrator (SO) to meet these requirements. Preliminary results over a realistic urban dataset show that utilising vehicular planning algorithms can lead to improved battery and QoS performance compared with traditional shortest path algorithms. The additional inclusion of desirability areas enabled more ambulances to be routed to their target destinations while utilising less energy to do so, compared to traditional and weighted algorithms without desirability considerations.

In Figure 9 we provide bias and MSE analysis of different algorithms on the domains that exhibit passive non-stationarity.

Kyiv, Ukraine – As luck would have it, emergency doctor Elina Dovzhenko was far enough from her vehicle when a Russian drone struck it, breaking the windshield and splattering pieces of shrapnel around. It was getting dark on July 9 in the bombed-out, nearly-abandoned city of Kupiansk which sits less than 5km (3 miles) from the front line in the northeastern Ukrainian region of Kharkiv – and just 40km (25 miles) west of the Russian border. But there was definitely enough light left for the Russian drone operator on the front line's opposite side to see that Dovzhenko's vehicle was a white ambulance with red stripes parked near a shelling-damaged hospital where she and her colleagues were. "We heard the drone move, it swirled and swirled around [the building], then we heard the blast," Dovzhenko, 29, told Al Jazeera. She and her colleagues were shocked and angry – but not surprised.

Nine people have been killed after a Russian drone hit a bus transporting workers in Ukraine, officials say. The attack occurred on Wednesday morning in the south-central city of Marhanets. Serhiy Lysak, regional chief of Dnipropetrovsk, said at least 30 people were injured, adding that "the number of victims is constantly growing". The attack comes as diplomats from the UK, France, Germany, the US and Ukraine are preparing to hold talks in London aimed at securing a ceasefire in the conflict. Russia launched a full-scale invasion of Ukraine on 24 February 2022.
