“…Power consumption figures correspond to peak measured values. The mean power consumption value is decreased via an ad-hoc power management of the sensing modules designed using formal methods [25]. Remind that we designed each sensor module as a stand-alone one for its partner’s owner to explore other exploitation routes.…”

Environment perception is crucial for the safe navigation of vehicles and robots to detect obstacles in their surroundings. It is also of paramount interest for navigation of human beings in reduced visibility conditions. Obstacle avoidance systems typically combine multiple sensing technologies (i.e., LiDAR, radar, ultrasound and visual) to detect various types of obstacles under different lighting and weather conditions, with the drawbacks of a given technology being offset by others. These systems require powerful computational capability to fuse the mass of data, which limits their use to high-end vehicles and robots. INSPEX delivers a low-power, small-size and lightweight environment perception system that is compatible with portable and/or wearable applications. This requires miniaturizing and optimizing existing range sensors of different technologies to meet the user’s requirements in terms of obstacle detection capabilities. These sensors consist of a LiDAR, a time-of-flight sensor, an ultrasound and an ultra-wideband radar with measurement ranges respectively of 10 m, 4 m, 2 m and 10 m. Integration of a data fusion technique is also required to build a model of the user’s surroundings and provide feedback about the localization of harmful obstacles. As primary demonstrator, the INSPEX device will be fixed on a white cane.

“…In Razavi et al 8 and Banach et al, 9 preliminary experience of the modelling of the data pathway was reported; this was subsequently extended to the lower level models included in the present paper. The paper 10 presents an overview of the project, and of early experience in the application of formal techniques, for a mixed commercial/technical audience. In Banach et al, 11 the role of formal techniques as experienced in the INSPEX Project is discussed as an element of a formal development review strategy.…”

INSPEX is an INtegrated Smart sPatial EXploration system. It relies on a family of sensors, like automated vehicles do, to provide enough information to a digital system for it to make reliable inferences about the location of obstacles and other impediments in its environment. Unlike the automated vehicle case, INSPEX is minaturised, because it is intended for lightweight applications and for portable use by humans, for example, visually impaired persons navigating outdoors (among many similar use cases). The complexity of this hardware-focused system merited the introduction of formal methods during its (essentially conventionally structured) development. The aim was to improve the dependability of parts of the implemented system and to estimate system characteristics via modelling and calculation that could not be obtained experimentally within the scope of the project.The paper overviews the experience of the very much human-in-the-loop use of formal techniques in the INSPEX Project and focuses particularly on the human issues that impacted the cooperation between the conventional techniques and formal methods.
