The Rollbot Tapeless Measurer


It had to happen eventually. Tape measures went digital some time ago, but those were laser-based. Now there’s a mechanical version that uses a simple serrated ring around its circular edge to roll like a wheel across surfaces – and the measurements appear in a digital diplay on the front of the ‘tape’. The Rollbot from iGaging can measure linear dimensions (the length of a board), are (the square inches of a board face), board feet (the length x width x thickness), round areas and diameters of cylinders such as turning blanks. It can also measure from one end of a shelf to the other simply by adding its own dimension to the measurement it rolls. The Rollbot can handle dimensions up to 144″, and measure at up to about 18 feet per second.
