Wireless Manhole Scanning Technology

The SPiDER Scanner is the first wireless and color manhole inspection technology in a lightweight and compact form factor. The SPiDER is a scanner that can calculate its position in the manhole shaft by using its sensor data to measure its incremental motion instead of the payout cable. SPiDER weighs less than 30 pounds and can be hand-carried to easements or other previously difficult to access sites. This wireless portability is possible because the processing computer and battery supply are built into the scanner. 

SPiDER collects millions of 3D measurements during each manhole inspection so the manhole can be measured to less than 5 mm accuracy. The point cloud can be used to evaluate the structural changes in a manhole before and after rehab. The SPiDER also provides live-video stream and recorded MPG video making it an ideal wireless tool for infiltration and inflow studies.
