Choosing the best board

[andryx97]

Hi i'm new in this forum and i hope to write in the right session. Anyway I have to build up a robot for the rcj rescue A competition and I'd like to know what is the best board for raspberry pi 2 model B that can manage motors and sensors in the same board.

Hi!
Welcome to the RPi forum.

I participated in the RCJ 2014 Flanders comptetition with a Raspberry Pi doing video analysis. Maybe read the blog article about my robot.

Because it has all the neccessary features packed in a small form factor, I used the pic Dwengo board (by the way, they've now also one based on an atmel microcontroller which is programmed like the Arduino's).
I used the model 1 B RPi and reached 14fps, so theoretically you should be able to get more than 80fps on the model 2 (haven't tested this yet ... but this would be way better).

If you've some questions, don't hesitate to post them on this forum.

Best regards,
Arne

Have you looked at the GoPiGo?

It's a Raspberry Pi robot. I don't know if it would fit the size parameters for the rescue competition, but I'd really like to know!

If you need a very powerful robot controller, take a look at RoboPi

http://RoboPi.com

- tested and supported with Raspberry Pi Models A / A+ / B / B+ / 2B

- RoboPi is based on an 8 core 32 bit RISC microcontroller

- 24 flexible I/O's (each I/O can be configured as digital input, digital output, servo output, pwm output, ultrasonic range sensor input)

- 8 channels of 12 bit analog input

- all I/O's use 3 pin servo style headers

To program RoboPi, you can use the easy to use C/C++ and Python RoboPi libraries.

You can download the assembly manual and user manual from the product page to see if it suits you.

Here is a link to a simple robot built with RoboPi, including sample Python code:

I'll be updating my Elf article soon, as I just added a Pi camera to Elf!
