The HRLV-MaxSonar-EZ4 is the narrowest beam width sensor that is also the least sensitive to side objects offered in the HRLV-MaxSonar-EZ sensor line. The HRLV-MaxSonar-EZ4 is an excellent choice when only larger objects need to be detected.
The MaxBotix low voltage MB1040 LV-MaxSonar-EZ4 offers very short to long-range detection and ranging, in an incredibly small package with ultra low power consumption. The MaxSonar-EZ4 detects objects from 0" to 254".
The MaxBotix high resolution, low voltage MB1033 HRLV-MaxSonar-EZ3 is a narrow beam sensor with good side object rejection.
This robot uses custom length sides and 13 inch tires with IG52 136 RPM motors. We have included everything to make it ready to run including batteries, chargers, and a controller.
SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader.
