MIT researchers have built a wearable sensor system that
automatically creates a digital map of the environment through which the
wearer is moving. The prototype system, described in a paper slated for
the Intelligent Robots and Systems conference in Portugal next month,
is envisioned as a tool to help emergency responders coordinate disaster
response.
In experiments conducted on the MIT campus, a graduate student wearing the sensor system wandered the halls, and the sensors wirelessly relayed data to a laptop in a distant conference room. Observers in the conference room were able to track the student's progress on a map that sprang into being as he moved.Connected to the array of sensors is a handheld pushbutton device that the wearer can use to annotate the map. In the prototype system, depressing the button simply designates a particular location as a point of interest. But the researchers envision that emergency responders could use a similar system to add voice or text tags to the map indicating, say, structural damage or a toxic spill.
"The operational scenario that was envisioned for this was a hazmat situation where people are suited up with the full suit, and they go in and explore an environment," says Maurice Fallon, a research scientist in MIT's Computer Science and Artificial Intelligence Laboratory, and lead author on the new paper.These Linear electric actuator slow down the movements and ensure there is stability while functioning;it also ensures that the output delivered is accurate. "The current approach would be to textually summarize what they had seen afterward 'I went into this room on the left, I saw this, I went into the next room,' and so on.Today, there are a variety of Robot system that are used for enhancing the overall efficiency levels of the packaging industry. We want to try to automate that."
