MS / 2001
Architecture of the MechSense rotary encoder

MechSense is a 3D printed multi-material rotary encoder designed in collaboration with the Human-Computer Interaction Lab in MIT CSAIL. The design of the encoder allows it to be fabricated in a single step, both removing the need for complex assembly and enabling the sensor to be fabricated in volume constrained systems where an off-the-shelf encoder would not fit.

The floating design of MechSense removes all parts of that would readily wear out and greatly simplifies the process of embedding rotary sensing in 3D printed designs. MechSense is a stepping stone towards a toolbox of 3D printable sensors, working towards a future where entire systems with structural, sensing, and computational elements can be taken directly off the print bed.
