A Method for Calibrating Work-Piece Orientation : Using a Dual-Axis MEMS Inclinometer

• An accelerometer based alignment system designed to align robotic tools and work-pieces in a Cartesian coordinate system is presented, with potential applications within the automated production industry. An overview of the underlying theory, used hardware, micro-controller implementation and performed experiments is presented. The developed theoretical model and prototype hardware is veried against both simulations and experiments, evaluating their performance and practical limitations. For a set of 2000 random initial misalignments with an amplitude in the range of 0° to 10°, the system achieved an alignment accuracy with a 3-sigma bound of 0.023° in the XY plane and 0.14° along the Z-axis. On average the used robot needed 20.86 s to align the used tool to stated accuracy.
