Abstract:
1. An electrical specific resistivity probing robot, comprising: a frame; a driving means including a power supply installed under the frame; a pair of insulating caterpillars installed to both sides of a lower portion of the frame and driven by the driving means, each of said insulating caterpillars including rollers at opposite ends of the caterpillar, a track encircling said rollers to define a track circumference, and wheels between the rollers and adjacent the track; a plurality of probing electrodes installed along track circumferences of the caterpillars at regular intervals; a slip ring continuously electrically slip-connected to the probing electrodes one by one and adapted for continuously providing electrical current to, and measuring potential differences among, the probing electrodes; and a cable electrically connected to the slip ring.
