Asuro educational robot
This is an educational robot kit produced by Dagu electronics based on the atmega 8 processor. The kit comes with all parts including a manual, CD, serial cable and IR serial link for wireless programming / data transfer. The robot comes with sensors for line following, oddometry (measuring the distance travelled by each wheel) and 6 bumper switches.
You will need soldering skills and a knowledge of "C" programming. An optional USB interface is available. Arduino users should be able to program this robot easily as earlier Arduinos used this processor.
There are add on modules available that allow for things such as ultrasound.
