It should be noted that, in this proposed control method, the spring and the damper in the electroadhesion model are not required, as the gap change is directly estimated by the gap sensor.
The popular capacitive sensor platform, for example, is susceptible to the erroneous effect of electrode tilting and high noise floor, both of which are exacerbated by the small form factor required of a nano-precision gap sensor.
Magnets with the same polarization are separated by a small gap d S whereas magnets with opposite polarization are separated by a gap d B. The sensor is placed on a lift which moves the sensitive volume constituted of a thin slice at a well-defined position through the object by varying the distance between the sensor and the object see Fig. 1d.
Construction and characterization of a SAW-based capacitive gap sensor to measure a 200 Hz gap frequency are described.
The gap is hidden and is normally in the order of micro meters, which can be hardly measured by using typical gap sensors.
A prototype that uses: a rotary table supported by ball bearings, non-contact gap sensors and a computer system that collects and process sensor readings has been developed.
In their work, the lateral wheel rail force was obtained from the wheel deformation by several non-contact gap sensors, while the wheel rail vertical and longitudinal forces were obtained from the deformation of axle box spring and the strain of swing arm.
With the Roomba, I was able to work around the issue by taping pieces of paper over the gap sensors and walling off the open stairwell to the basement with one of its virtual wall emitters.
We allow for gaps in the maps by assigning a gap penalty that penalizes gap insertions between highly interacting residues.
Activated, like most of the works here, by a motion sensor, its rapid-fire movements unnerve.
