== Bicycle overtaking experiment ==

Goal of this experiment is to measure how
drivers overtake cyclist.

Using two sonar rangefinders located
on the side of the bike we measure the distance
of the passing car and possibly its speed.

=== Hardware ===

* Velobot Prototype #2
* 2x [http://www.maxbotix.com/Ultrasonic_Sensors/MB1010.htm MaxBotix LV‑MaxSonar‑EZ1]

Two rangefinders are connected to FRDM-KL25Z board
which features ARM Cortext-M0 with 16-bit SAR ADC.

ADC readings are transfered to Raspberry Pi over
USB serial and recorded for further analysis.
