A collapsible steering column assembly comprising a steering shaft that is supported within a steering column shroud, the shroud comprising an upper shroud portion and a lower shroud portion, in which the upper shroud portion is located towards the end of the steering shaft that is nearest the steering wheel and the lower portion is located towards the end of the shaft furthest from the steering wheel, the upper portion being at least partially received within the lower portion so that the upper portion can telescopically collapse into the lower portion during a crash, a support bracket that in use is secured to a fixed part of the vehicle and includes two support bracket arms that depend from a base portion to embrace the shroud, a clamp rail that is releasably secured to the upper shroud portion, the clamp rail including a slot that extends generally horizontally, and a clamp pin that extends through an opening in each of the arms of the bracket and through the generally horizontal slot in the rail, the clamp pin carrying a clamp mechanism that is movable between an unclamped position in which the rail can move freely relative to the clamp pin and a clamped position in which the rail is fixed relative to the clamp pin. The rail is secured to the upper shroud portion by a deformable tab which protrudes from the upper shroud portion to hook onto a part of the rail that faces the steering wheel end of the shroud. In use of the assembly with the cam mechanism in the clamped condition the tab is deformable under a predefined load applied to the upper shroud so as to unhook from the rail allowing the upper shroud to move axially relative to the rail and hence relative to the clam pin to permit collapse of the steering column shroud.

Autonomous robots, capable of independent and intelligent navigation through unknown environments, have the potential to significantly increase human safety and security. They could replace people in potentially hazardous tasks, for instance search and rescue operations in disaster zones, or surveys of nuclear/chemical installations. Vision is one of the primary senses that can enable this capability, however, visual information processing is notoriously difficult, especially at speeds required for fast moving robots, and in particular where low weight, power dissipation and cost of the system are of concern. Conventional hardware and algorithms are not up to the task. The proposal here is to tightly integrate novel sensing and processing hardware, together with vision, navigation and control algorithms, to enable the next generation of autonomous robots. At the heart of the system will be a device known as a vision chip. This bespoke integrated circuit differs from a conventional image sensor, including a processor with each pixel. This will offer unprecedented performance. The massively parallel processor array will be programmed to pre-process images, passing higher-level feature information upstream to vision tracking algorithms and the control system. Feature extraction at pixel level results in an extremely efficient and high speed throughput of information. Another feature of the new vision chip will be the measurement of time of flight data in each pixel. This will allow the distance to a feature to be extracted and combined with the image plane data for vision tracking, simplifying and speeding up the real-time state estimation and mapping capabilities. Vision algorithms will be developed to make the most optimal use of this novel hardware technology. This project will not only develop a unique vision processing system, but will also tightly integrate the control system design. Vision and control systems have been traditionally developed independently, with the downstream flow of information from sensor through to motor control. In our system, information flow will be bidirectional. Control system parameters will be passed to the image sensor itself, guiding computational effort and reducing processing overheads. For example a rotational demand passed into the control system, will not only result in control actuation for vehicle movement, but will also result in optic tracking along the same path. A key component of the project will therefore be the management and control of information across all three layers: sensing, visual perception and control. Information share will occur at multiple rates and may either be scheduled or requested. Shared information and distributed computation will provide a breakthrough in control capabilities for highly agile robotic systems. Whilst applicable to a very wide range of disciplines, our system will be tested in the demanding field of autonomous aerial robotics. We will integrate the new vision sensors onboard an unmanned air vehicle (UAV), developing a control system that will fully exploit the new tracking capabilities. This will serve as a demonstration platform for the complete vision system, incorporating nonlinear algorithms to control the vehicle through agile manoeuvres and rapidly changing trajectories. Although specific vision tracking and control algorithms will be used for the project, the hardware itself and system architecture will be applicable to a very wide range of tasks. Any application that is currently limited by tracking capabilities, in particular when combined with a rapid, demanding control challenge would benefit from this work. We will demonstrate a step change in agile, vision-based control of UAVs for exploration, and in doing so develop an architecture which will have benefits in fields as diverse as medical robotics and industrial production.
