My PI2 will arrive on Wednesday.
What problems can I anticipate with my GoPIGo?
Hey Papa Dilbert,
There is one issue with the motors we solved with software. This is pretty clearly explained in these posts below. I think you should take a look at these two posts:
http://www.dexterindustries.com/forum/?topic=grovepi-firmware-update-v1-2-2
and
http://www.dexterindustries.com/forum/?topic=gopigo-motor-not-working-one-starts-another-doesnt
Other than that, it should be a lot of fun! Be sure to post some pictures of your build!
An update. We’ll have a blog post up tomorrow about this.
For now, you can download an updated Raspbian Image here:

I assembled my GoPiGo with my Pi 2. The only problem with the build is that the power connector from the battery pack to the GoPiGo is a bit too tall. The PI 2 bumps into it. A shorter 2-pin connector would solve this problem but I don’t think this is a show-stopper.
I attempted to run my first example. I got the message:
RuntimeError: This module can only be run on a Raspberry Pi
The following is a clip of the command execution
Traceback (most recent call last):
File “basic_robot.py”, line 23, in <module>
from gopigo import * #Has the basic functions for controlling the
GoPiGo Robot
File “/usr/local/lib/python2.7/dist-packages/GoPiGo-0.0.0-py2.7.egg/gopigo.py”,
line 20, in <module>
import RPi.GPIO as GPIO
RuntimeError: This module can only be run on a Raspberry Pi!
pi@raspberrypi ~/GoPiGo/Software/Python/Examples/Basic Robot Control $
Perfect, glad someone has tried this!
These commands should get you up and going, if you have pip installed:
sudo apt-get install python-dev
sudo pip install -U RPi.GPIO
sudo reboot
I think! Can you give that a shot and see if it heals the issue?
Reset on the pictures I think. They should be gone. Try again?
This image shows the power connector that bumps into the PI2
All the commands suggested above completed successfully.
I retried the example:
pi@raspberrypi ~/GoPiGo/Software/Python/Examples/Basic Robot Control $
sudo python basic_robot.py
Traceback (most recent call last):
File “basic_robot.py”, line 23, in <module>
from gopigo import * #Has the basic functions for controlling the
GoPiGo Robot
File “/usr/local/lib/python2.7/dist-packages/GoPiGo-0.0.0-py2.7.egg/gopigo.py”,
line 30, in <module>
bus = smbus.SMBus(1)
IOError: [Errno 2] No such file or directory
What else do I need to install?
Hey,
You need to add these lines to your /boot/config.txt and reboot:
dtparam=i2c1=on
dtparam=i2c_arm=on
Tell us if this works.
