Hello everybody,
Wish you a very happy new year 2011.
A brief: We are developing Indoor robot which needs good localization technique. We do have Laser Range finder and Encoder but we are still lacking in getting a good localization.
We are looking out for a sensor IMU gyro which can tell us about X, Y, Z location of Robot in map.
We are using dsPIC for interfacing.
We saw Atomic IMU 6 Degrees of Freedom - XBee Ready module. Does this module suffice our requirement? How can i interface this module to our existing dsPIC? We are new to this sensor so need some guidance to choose a proper module.
Hello,
Thank you for your reply.
Is “Atomic IMU 6 Degrees of Freedom - XBee Ready” module directly attachable by USB? We are using Intel Atom processor board and dsPIC is also attached to the same board. If IMU can be attached through USB then i can directly make connection between Intel Board and IMU.
I can surely provide information about dsPIC if above solution is not possible.
Thanks,
Prasad
I am planning to purchase it from you so clarifying my doubts a bit more. As i said in my previous thread about USB port;even now serial port is fine for me. I have open serial ports for Intel Atom board. So according to your answer, do you mean i can directly attach IMU sparkfun to serial port and make it work for my robot?
I only have a concern with my choice. I saw “Analog Device” Sensors and “Sparkfun” sensors. Which company would you suggest for the selection of IMU, knowing my scenario (mentioned in first thread)?
Also, do you have 9 Degrees of Freedom - Razor IMU - AHRS of Sparkfun available?
Are there any other accessories need to buy along with the Sensor?
What about 9DOF board? Is it directly attachable by USB? or need break out board in between?
So, is it something like, 9DOF razor will be attached to the break out board and break out board attached to main computer USB?
like, 9DOF razor => breakout => main computer’s usb
There is no USB port on the Atomic IMU 6 Degrees of Freedom board, so you either need a USB to serial adapter or an XBee module. The specifications indicate the board uses 3.3V but tolerates up to 5V. We suggest using a 3.3V serial cable.
We welcome new posts - no need to apologize. If you want to connect the sensor directly to your serial port, you may need a few additional electronics such as a resistor. We still suggest using a serial breakout board to help with wiring. “Sparkfun” is not the manufacturer of the chip itself - they produce breakout boards, so you should select the board based on your required specifications rather than the chip itself. We will be adding the 9DOF Razor shortly (RB-Spa-393). If you would like to order it before it is live on the RobotShop website, submit a ticket to the sales department via the Support Center requesting a quote for this product number, and provide your telephone number and complete address. Once again this sensor does not have a direct serial or USB connection, so we suggest using a breakout board.
Correct, the 9DOF razor also does not include a serial or USB port and would also need something between it and your computer. Since direct connection seems to be important to you, consider the Phidgets USB 9DOF IMU which is powered by USB.
An IMU will provide you information regarding the attitude (roll, pitch and heading) of the robot as well as information regarding shocks of if it is falling.
As for the compatibility with dsPIC, it is hard to say since we are not familiar with it. Could you please provide a link to some further information or some specification about it? We can try to help you assess the compatibility.
