Is there a mechanism to connect the structure sensor to Linux (Ubuntu in my case) via wireless?
Not currently, you will still need to connect Structure Sensor directly to some device first – are you attaching it to an iPad?
No. I am using it in a robot.
You can attach a phone to the robot and use some remote desktop like apps to control it, or you might use a small sized computer on the robot, attach the sensor to the computer, and then use wifi to transfer the data realtime to process somewhere else.
