ASURO ROBOT PDF

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. We enable science by offering product choice, services, process excellence and our people make it happen.

A comprehensive manual is supplied to assemble the Asuro robot. Odometric speed control Odometric infrared LED: Depending on which button s that are pressed, different resistors are connected on the asuro PCB and an unique analogue signal will return to analogue in 4, defining the buttons pressed. This effects the Asuro robot when driving in a straight line or turning. De distance between the shroud and the surface is minimal about 0,5 mm and that’s aauro the surrounding light has no more influence.

Then I took a small connector 3 pins from an old PC and connected that to the original battery pack. This has an effect on the measuring values of the sensors. In reality this was not mm.

Odometer sensors and line following sensors are now read continuously and the values of the sensors are continuously available as global variables. You can upload programs straight from the Arduino environment. After I had removed the motor from the circuit board the problem was gone. I wrote a small program that continues sends the data from the odometer sensors and the line follow sensor via the infrared transceiver to the PC.

Fortunately, you can use the ATmega8 from any Arduino board instead. Turn After that I wrote a small program that turns the Asuro robot degrees.

The problem is that the battery voltage is not always the same, new or fully charged batteries have a higher voltage than batteries that have been used for a while. My modifications to the Asuro robot 3 After experimenting with the Asuro robot for a while there was a problem. With this system the voltage for the Asuro electronics is now always 5. The Asuro robot learns the maze and can drive the shortest route.

If there is an obstacle, the Asuro robot drives an alternative route. My modifications to the Asuro robot 1 After assembling the Asuro robot Rrobot have tested the sensors. Sources for Electronic Parts. But take a look at “My modifications to the Asuro robot” before assembling the Asuro robot.

I also made a cover for the odometry sensors. In the future I will make assuro battery-pack with capacity of mAh. My modifications to the Asuro robot 4 Not every Asuro robot is exactly the same. I started testing the Asuro robot and the problem happened when the left motor was turning, but not always.

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.

Arduino on other Chips.

For more info pleae look at this Forum Post. The major differences are: When there is strong sun-light the odometry sensors are nor working correctly. This because the supplied Linux version is no longer usable on a modern Linux system due to its age. I decided to make a personal Asuro library based on the Asuro library v2. On the axles with the wheels I installed small spacers to correctly align the gear and wheel.

Related Hardware and Initiatives. 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. A dedicated interrupt routine for detection of the switches and improved routines for turning and driving with the odometer sensors. I discovered that the reading of the odometer sensors was disrupted by other functions.

The odometer sensors are less reliable when the voltage is low. I wanted a little bit more than that and decided to upgrade the battery system. I wrote a program that controls the motors and LEDs with the switches.

Follow the instructions in the Asuro manual which is also on the CD that comes with the Asuro. Every 1 ms one of the four sensors is read, so after every 4 ms all the sensor values are refreshed.
