Here you can find the detailed ARX ASURO Documentation and Datasheets of the parts used on ARX ASURO. You will need the Acrobat Reader to view these. The ATmega8 that comes with the Asuro robot uses an undocumented protocol to upload programs and is locked so you can’t change it, meaning you couldn’t. Learn more about Asuro Robot.

After I had removed the motor from the circuit board the problem was gone. The crossroads have a grey colour. The Asuro robot learns the maze and can drive the shortest route.
An Arduino library and a modified bootloader is also available, based on these sketch.
For the flashing I use the Windows version of the flash program via Wine. And the driving speed is also dependent of the battery voltage. The software is a little bit old My modifications to the Asuro robot 1 After assembling the Asuro robot I have tested the sensors. azuro
But a standard linear voltage regulator uses about 2 Volts to do its job. If there is an obstacle, the Asuro robot drives an alternative route.
The connector on the Asuro robot has an extra pin that prevents that the connector from the battery-pack is connected in the wrong way. You can use four normal or four rechargeable batteries. LineData After that I wrote a small program that sends the value of the line follow sensor on the Asuro robot to the PC.
Arduino Playground – Asuro
Fortunately, you can use the ATmega8 from any Arduino board rohot. In reality this was not mm. I have changed the standard value of 61 to Gear on minimum distance 0 mm: The program uses the line follow sensor to stay on the black line.
The playground is a publicly-editable wiki about Arduino. I placed a piece of isolation tape on the circuit board and the problem is solved.
This has an effect on the measuring values of the sensors. This library has functions for reading the odometer and line following sensors, you can make turns or ride for a certain distance and much more. The normal serial commands from the reference should work. Checkout the Asurino page for further information. If you are getting information from other sensors, the reading of the odometer sensor is halted.
Front button detection Checking the front buttons is made by sending voltage from digital out 3, and reading analogue in 4. I built a small shroud around the line follow sensor.
The program uses the line following sensor to stay asro the black line and switches to detect a collision. Board Setup and Configuration. Replacing the ATmega8 The ATmega8 that comes with the Asuro robot uses an undocumented protocol to upload programs and is locked so you can’t change it, meaning you couldn’t use Arduino to upload programs to it. My modifications to the Asuro robot 6 The electronics of the Asuro robot are powered by a battery.
On the axles with the wheels I installed small spacers to correctly align the gear and wheel. A better solution is to use a switching voltage regulator. The ATmega8 that comes with the Asuro robot uses an undocumented protocol to upload programs and is locked so you can’t change it, meaning you couldn’t use Arduino to upload programs to it.
Connect the USB cable to the Arduino board and the computer. The solution is to make a small circuit that enables the switching voltage regulator only if the input voltage is higher than 4.
I also applied this to the right motor. My conclusion is that the metal cover of the motor caused a short-circuit on the circuit board. You can upload programs straight from the Arduino environment. But I also want to recognise a crossroad.
Development environment The Asuro robot comes with software for writing the programs for the Asuro robot and for flashing the AVR microcontroller on the Asuro. Motor left, white surface: But there is a gobot problem, when the input voltage is between 2. Then I took a small connector 3 pins from an old PC and connected that to the original battery pack.
