The RollBot is a handy workshop assistant. Being able to measure things where a regular measuring tape might have a problem. Curved surfaces, winding paths, cylinder diameter, area and a few others. The Rollbot from iGaging uses a simple serrated ring around its circular edge to roll like a wheel across any flat, curved, or irregular surface with the measurement appearing in a digital display on the front of the tool.

The Rollbot can easily measure linear dimensions like the length of a board. But, it can also calculate the square inches of a board face, or calculate board feet (the way sawmills price lumber with a bd ft = 1’x1’x1″), or calculate the round area and diameter of cylinders such as tree trunks or turning blanks by measuring the circumference. Plus, it can do corner and inside measurements such as from one end of a bookshelf to the other by merely adding its dimension to the measurement it rolls.

Loaded with great features:

  • Roll it over a surface to measure it
  • Starts and stops measuring at the touch of a button
  • Measures in either decimal or fractional inches, or decimal metric increments
  • Easy-to-use mode settings to compensate for measuring into corners
  • In addition to linear measurements, you can determine the surface area of rectangular objects like tabletops and can measure lumber in board feet
  • For turning blanks, tree limbs and any other cylindrical object, you can quickly determine the diameter of the cylinder, as well as calculate the surface area
  • Smaller than a 12′ rule, the RollBot measures up to 144″ with 1/32″/0.01″ resolution in either direction. Accuracy is +/- 0.1% of calculated value. Auto powers off in 30 minutes.
