how to start(compile) for a newbie #63

Closed liwenz closed 3 years ago

liwenz commented 3 years ago

I hope to start the project. I have installed ros kenetic on ubuntu16 in vmware and learned tutorial for ros. I could not find ubuntu 16 for pi 3B and install pi os and compile ros kenetic on it(ok). Now I try to compile on ubuntu 16 at first. in ~/catkin_ws/src

leon@ubuntu:~/catkin_ws/src$ git init Initialized empty Git repository in /home/leon/catkin_ws/src/.git/ leon@ubuntu:~/catkin_ws/src$ git pull https://github.com/mike4192/spotMicro

now the file and directory is as follow: `leon@ubuntu:~/catkin_ws/src$ ls ros-i2c*

The following CMake error indicates that you either need to install the package with the same name or change your environment so that it can be found.

I tried: https://github.com/dheera/ros-pwm-pca9685 sudo apt-get install libi2c-dev done

how to resolve no 'i2cpwm_board'?

wget from url = https://gitlab.com/bradanlane/ros-i2cpwmboard.git then : leon@ubuntu:~/catkin_ws/src$ unzip -l r*.zip Archive: ros-i2cpwmboard-master.zip 9d5b00da8dbdbc542343b65f87f505b0ddb33f8f

liwenz commented 3 years ago

I make a new dog_ws workspace. cp ros-i2cpwmboard-master => ros-i2cpwmboard

then i2c is ok but -- Could not find the required component 'joy'.

liwenz commented 3 years ago

sudo apt-get install ros-kinetic-joy sudo apt-get install ros-kinetic-rplidar-ros sudo apt-get install ros-kinetic-hector-slam

then joy is ok but

git submodule command should be in src folder: At first, it said some is not free. I mv it,then it's ok as follow:

The compile process for step by step At first, you should install ros on ubuntu Then make a workplace as dog:

sudo apt-get install ros-kinetic-rplidar-ros sudo apt-get install ros-kinetic-hector-slam sudo apt-get install libi2c-dev

They should be installed, I have done them before.

leon@ubuntu:~/dog/src$ cd .. leon@ubuntu:~/dog$ catkin_make

Then compile 100% finished.

liwenz commented 3 years ago

I tried to compile on raspberry os PI b3, ros--geometry-msgs needed. and
sudo apt-get install ros-kinetic-joy sudo apt-get install ros-kinetic-rplidar-ros sudo apt-get install ros-kinetic-hector-slam can't be found I only compiled the core version ros and no vision.

mike4192 commented 3 years ago

I wouldn't recommend trying to compile ros from source on raspbian OS, I tried it early on and ran into issues. It also takes very long to compile. I'm impressed you got as far as you did. The issues can be overcome but it will probably be tedious and a long drawn out process. If you wanted to continue this way, you would also need to compile those packages from source as well in your catkin ws src directory (joy, rplidar, hector-slam, etc...). You'd need to download their source from their respective github pages (making sure to download the ros kinetic versions if they have a kinetic specific branch).

Why not just utilize premade ubuntu 16.04 RPi images from ubiquity robotics like I recommend in the documentation? These come preinstalled with ROS kinetic basically all ready to go, and then you can install the required packages via sudo apt-get no problemo.

You just need to follow the instructions to modify the wifi settings so it will connect to your local wifi network, then you wont have to directly wifi connect to the RPi.

liwenz commented 3 years ago

Thanks for your reply. before, I tried ubiquity robotics, sometime it will be dead and I don't like the face. I tried the ubuntu,but only find the 20.04, it could not boot.

As your recommand, today I tried them again.

I tried ubiquity robotics, but sudo apt-get install ros-kinetic-rplidar-ros fail. I tried to catkin_make but some error(need something).

lots of people said 20.04 could not boot, I boot to choose language, but it can't know my keyboard and mouse. Sb said 20.10 could boot, I did . 20.10 could boot,but firefox is too slow. I got ubuntu 18, it work well . I install ros/melodic. That's ok. https://releases.ubuntu-mate.org/archived/18.04/arm64/

I tried to compile as I did in ubuntu16. Everything seem fine, until compile to 78%. dog/src/ros-i2cpwmboard/src/i2cpwm+ccontroller.cpp 5559:13: error /i'i2c_smbus_write_byte_data' was not declared in this scope

lots of such error

liwenz commented 3 years ago

I have compiled it 100% on ubuntu18 (download from: https://releases.ubuntu-mate.org/archived/18.04/arm64/) ros/melodic ( I install it as http://wiki.ros.org/melodic/Installation/Ubuntu)

it is almost same as I did last post. except: sudo apt-get install ros-melodic-joy sudo apt-get install ros-melodic-rplidar-ros sudo apt-get install ros-melodic-hector-slam

the i2ccpwm need change as git: https://github.com/EricWiener/ros-i2cpwmboards/commit/9ae9556a043ac2fe75a3251c9b28318b5383e744

Next I need test and let it walk.

liwenz commented 3 years ago

I don't know how to test at first.

Yesterday I run follow cmd, and it told me no i2c_pwmboard. Today I installed the i2c_pwmboard ( and no serve connected )and run again:

roslaunch spot_micro_motion_cmd motion_cmd.launch

I got lots of follow error and never stop:

Hmm, I sometimes see this error but to be honest I'm not sure what causes it. I think you may need a servo connected.

Looking into the source for the i2cpwm_board package, it looks like this is an error resulting when the actual i2c writing operation fails. For example, from the source code:

  555     if (0 > i2c_smbus_write_byte_data (_controller_io_handle, __CHANNEL_ON_L+4*channel, start & 0xFF))
  556         ROS_ERROR ("Error setting PWM start low byte on servo %d on board %d", servo, _active_board);
  557     if (0 >  i2c_smbus_write_byte_data (_controller_io_handle, __CHANNEL_ON_H+4*channel, start  >> 8))
  558         ROS_ERROR ("Error setting PWM start high byte on servo %d on board %d", servo, _active_board);
  559     if (0 > i2c_smbus_write_byte_data (_controller_io_handle, __CHANNEL_OFF_L+4*channel, end & 0xFF))
  560         ROS_ERROR ("Error setting PWM end low byte on servo %d on board %d", servo, _active_board);
  561     if (0 > i2c_smbus_write_byte_data (_controller_io_handle, __CHANNEL_OFF_H+4*channel, end >> 8))
  562         ROS_ERROR ("Error setting PWM end high byte on servo %d on board %d", servo, _active_board);

Make sure you can see the pwm board on your RPi. See the following page, section "Testing I2C": https://learn.adafruit.com/adafruits-raspberry-pi-lesson-4-gpio-setup/configuring-i2c#testing-i2c-2724591-14 For example, running the command like: sudo i2cdetect -y 1

Also, you are running the i2cpwmboard on the raspberry pi right? And not on your PC?

Usually if I see it I try relaunching, or power cycling everything. I would verify you are powering all the boards with the correct voltages and have a common ground for everything.

You can also try running the python script for moving servos with the i2cpwmboard library. roslaunch servo_move_keyboard keyboard_move.launch

You can run the code somewhat like a simulation by launching the following:

On either the raspberry pi or a computer: roslaunch spot_micro_motion_cmd motion_cmd.launch run_standalone:=true

On a computer: roslaunch spot_micro_keyboard_command keyboard_command.launch run_rviz:=true

You should then be able to control the robot software and see it walk around in the visualization.

Thanks， I'll try tomorrow. I'm in Canada. It's 23:15

I will change this issue as how to start (compile) and open a new issue as how to start (test and run it)
