The ability to wield tools was once considered exclusive to human intelligence, but it's now known that many other animals, like crows, possess this capability. Yet, robotic systems still fall short of matching biological dexterity. In this paper, we investigate the use of Large Language Models (LLMs), tool affordances, and object manoeuvrability for non-prehensile tool-based manipulation tasks. Our novel method leverages LLMs based on scene information and natural language instructions to enable symbolic task planning for tool-object manipulation. This approach allows the system to convert the human language sentence into a sequence of feasible motion functions. We have developed a novel manoeuvrability-driven controller using a new tool affordance model derived from visual feedback. This controller helps guide the robot's tool utilization and manipulation actions, even within confined areas, using a stepping incremental approach. The proposed methodology is evaluated with experiments to prove its effectiveness under various manipulation scenarios.

This paper provides a collision avoidance perspective to maritime autonomy, in the shift towards Maritime Autonomous Surface Ships (MASS). In particular, the paper presents the developments related to the Greenhopper, Denmark's first autonomous harbour bus. The collision and grounding avoidance scheme, called the Short Horizon Planner (SHP), is described and discussed in detail. Furthermore, the required autonomy stack for facilitating safe and rule-compliant collision avoidance is presented. The inherent difficulties related to adhering to the COLREGs are outlined, highlighting some of the operational constraints and challenges within the space of autonomous ferries and harbour buses. Finally, collision and grounding avoidance is demonstrated using a simulation of the whole Greenhopper autonomy stack.

Fully or partial autonomous marine vessels are actively being developed by many industry actors. In many cases, the autonomous vessels will be operating close to shore, and within range of a Remote Control Center (RCC). Close to shore operation requires that the autonomous vessel is able to navigate in close proximity to other autonomous or manned vessels, and possibly in confined waters, while obeying the COLREGs on equal terms as any other vessel at sea. In confined waters however, certain COLREGs rules apply, which might alter the expected actions (give-way or stand-on), depending on the manoeuvrability of the vessels. This paper presents a Situation Awareness (SAS) framework for autonomous navigation that complies with COLREGs rule 9 (Narrow Channels). The proposed solution comprises a method for evaluating the manoeuvrability of a vessel in confined waters, for assessing the applicability of COLREGs rule 9. This feature is then integrated into an already existing SAS framework for facilitating COLREGs-compliant navigation in restricted waters. The applicability of the proposed method is demonstrated in simulation using a case study of a small autonomous passenger ferry.

A new four-wheeled robot designed to carry anything from parcels and drinks to babies and health monitors, has been developed by Hyundai. The Mobile Eccentric Droid (MobED) robot has a low and flat body that is perfect for'stability and high manoeuvrability' tasks, according to Hyundai. It will be officially unveiled at the Consumer Electronics Show (CES) 2022 in January, where it will be shown undertaking tasks in complex and challenging environments. In a promotional video for the device, it can be seen carrying a baby and crossing a hill while loaded with a pyramid of glasses filled with champagne. MobED is 26 inches long, weighs 110lb and would be a useful'mobility device for hte elderly or disabled,' Hyundai explained. No pricing details have been released for the device, and Hyundai is yet to say when it will be commercially available.

Stunning concept images have revealed an Italian designer's unique vision for a retro-inspired flying vehicle. Lazzarini Design Studio has merged futuristic technology with 1920s luxury for its Hover Coupe, which resembles a cross between a Rolls-Royce and something from a science fiction film. According to its creators, the hover car will be able to reach a top speed in excess of 342mph (550kph) using four jet turbines. Stunning concept images have revealed an Italian designer's unique vision for a retro inspired flying vehicle. The concept car is based on the Isotta Fraschini Tipo 8, an Italian luxury car manufactured from 1919 to 1924, which was the main rival to the Rolls-Royce.
