This is a bracket and articulating mount for the QTR-8A / QTR-8RC line sensors from pololu.com. This parametric bracket holds the line sensor at the optimum distance from the line and isolates the sensors from one another with fingers. This bracket was used on the basic robotics platform from digilentinc.com and performed flawlessly in a recent line following robot competition.


the QTR-8A sensor should click into place in the sensor mount. All parameters are adjustable via the openscad file.
