Aim of this project is to build a low-cost and reliable distance sensor. Commercial devices are either unreliable (Sharp IR distance sensors, SRFxx ultrasonic rangefinders) or way too expensive (SICK / Hokuyo devices). 

Basic idea is described in [[http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4543666|[1]]]. 


===== Status =====
  * Find suitable cheap CMOS sensor and optics [TODO]
  * Find suitable laser module [TODO]
  * Make stationary mounting frame [TODO]
  * Design DSP circuit for fast image processing [TODO]
  * Make rotary platform for 360° planar scanning [TODO]
  * Use in robots! [TODO]
