Beta install

The current Beta application features recording movements in the gigabrain.io cloud where you can analyze and share the movement. In the beta version only the verified movements are shared.

Movement install instructions

1. Read Instructions

Read the full instructions and decide if you will be using PiBlaster Software PWM from GPIO pins or PCA9685 external board

Read : Instructions

2. Prepare your device

Movement will use by default the Vorpal configuration for the movements by using a Raspberry Pi as controller board.

Write : Feedback

7. Plan new movement

In the beta test you can plan your own movement in an planning Excel and you can send the Excel as attachment with email to info@gigabrain.io and ask to add the movement.

Plan : Download movement planning Excel

Currently tested with versions Raspberry PI 3 B V1.2 model and 3+ model. Raspbian 4.9 Please test with your Raspberry device and send feedback.

How to install with a script ?

DOWNLOAD INSTALL SCRIPT

Download the Install script in your Raspberry Pi Terminal Console window in your home folder and run it with an example below.

wget http://gigabrain.io/demo/movement/GigaBrainInstallMovement.sh -O ~/GigaBrainInstallMovement.sh
chmod +x ~/GigaBrainInstallMovement.sh
~/GigaBrainInstallMovement.sh

Here are instructions on the gigabrain.io with the newest Raspberry Pi Buster kernel version. The Buster kernel version has a default for Java version 11 and currently the Pi4J project that we user depends on the Java version 8. We will upgrade to the new version as soon as it is released. To get the software running please downgrade the Java to version 8 with following instructions from Downgrading Java 11 to Java 8

The service start takes around 8 seconds. Wait for that amount at least. You can use the following command to see from the log when the service has fully started. tail ~/gigabrain/logs/movement.log

In the HOME folder the script creates folder ~/gigabrain downloads the GigaBrain Movement version and creates three scripts for running the service. The log files are created in ~/gigabrain/logs You can launch the Movement version with script startMovement.sh PCA9685_startMovement.sh or LX16A_startMovement.sh The service runs in a port 5800, open up a web browser http://RPI_IPADDRESS:5800 or http://localhost:5800

GigaBrain Source code uses the following library dependencies: Spring Boot, Pi4J, AngularJS

How to connect with PiBlaster ?

Setup suggestion for Micro Servos (DEMO version uses pins 4,17,18,27,21,22,23,24)

Install the PiBlaster from

https://github.com/sarfata/pi-blaster

PiBlaster by default has 9 output GPIO pins 4,17,18,27,21,22,23,24,25 and the default PWM output is 100Hz 
using one GPIO pin verified by testing with an oscilloscope.
If you are running with Pi Blaster make sure that you do not use any GPIO pins for input devices.
The reserved GPIO pins for output are 4,17,18,27,21,22,23,24,25
Note that you have to restart the Raspberry Pi Raspbian or shutdown the operating system or 
the application from the interface "Shutdown" Button to release the output GPIO pins for other use. 
Do not attach any input sensors or other devices to these output reserved GPIO pins
unless you have restarted the Raspberry Pi.
You can also release the PiBlaster pin by calling release for the pin number from command line:
echo "release 4" > /dev/pi-blaster
echo "release 17" > /dev/pi-blaster
echo "release 18" > /dev/pi-blaster
echo "release 27" > /dev/pi-blaster
echo "release 21" > /dev/pi-blaster
echo "release 22" > /dev/pi-blaster
echo "release 23" > /dev/pi-blaster
echo "release 24" > /dev/pi-blaster
echo "release 25" > /dev/pi-blaster


The configuration parameters for PiBlaster pins:
CONTROLLING_ENABLE_PIBLASTER = Boolean (true or false) Turn on Raspberry Pi PiBlaster configuration
CONTROLLING_PIBLASTER_OUTPUT_TAGS = String separated with , List the hashtags that are mapped to pins in the same order as PINS (not used in demo), default r1,r2,r7,r8,l1,l2,l7,l8
CONTROLLING_PIBLASTER_OUTPUT_PINS = String separated with , List the pin numbers that are mapped to output GPIO ports in the same order as TAGS (not used in demo), default 4,17,18,27,21,22,23,24
CONTROLLING_STOPTIME = After the movement cycle how long to wait before the movement stop signal is sent, default 500 ms 
CONTROLLING_DELAYTIME = How much delay there is between single movements, default 10 ms
CONTROLLING_SHUTDOWNTIME = How long the controller is on from the last control movement, default 300000ms 5min

Run command:
java -jar ~/gigabrain/movement-0.0.5-SNAPSHOT.jar --CONTROLLING_ENABLE_PIBLASTER=true > /home/pi/gigabrain/logs/movement.log 2>&1 &

The pins to control for PiBlaster in this DEMO version is 18, GPIO pins 4,17,18,27,21,22,23,24. The user interface has 18 controls, 9 for right and left side. The pins to control for PCA9685 in this DEMO version is 18, one board in 0x40 bus is configured automatically. The user interface has 18 controls, 9 for right and left side.

How to secure the controller ?

This version does not secure the controller interfaces, so make sure to use it only with a secured Wifi connection. Currently the security with username and password is disabled in this version. Contact us and ask about the premium version where the security can be enabled.

How to setup configuration for your robot ?

The DEMO version has Two controllers one for right side (r1 - r3) and one for left side (l1 - l3) for X, Y and Z directions. Actual GigaBrain controller touch interface has 3 controllers on right (r1 - r9) and 3 controllers on left (l1 - l9) for X, Y and Z directions.

Example configuration for Vorpal robot in DEMO for PCA9685

The image shows first the Controller movement id then the PCA9685 board pin number and then Vorpal leg number Controller movement id = PCA9685 board pin number -> Vorpal leg number

Example configuration for Vorpal robot in DEMO for PiBlaster

Because there is only 9 pins used in piblaster the configuration has changed to use 8 controllers, 2 legs on each side.

How to use GigaBrain ?

Make sure that you have Raspbian 4.9 installed on your SD card Install the newest Raspbian official installation

Share the Wifi hotspot with iPhone or iPad, Android phone or tablet, PC with a touch screen and after that connect your Raspberry Pi to the same Wifi with your mobile phone

You can also connect your touch screen and Raspberry Pi with the same Wifi hotspot device, as long as the devices see each others IP addresses.

One option also is to create a Wifi hotspot with your Raspberry Pi and connect your mobile device to that Wifi. This is an advanced option

Find the IP address of your Raspberry Pi with Command line command: host raspberrypi

Install GigaBrain to your Raspberry Pi and setup the device. If you are running with Pi Blaster make sure that you do not use any GPIO pins for input devices. The reserved GPIO pins for output are 4,17,18,27,21,22,23,24,25

Open up the browser from your mobile phone and type the address for example: http://192.0.1.23:5800 Make sure that the port number :5800 is added after the IP address of your Raspberry Pi

Stop the application with the interface "Shutdown" button or restart your Raspberry Pi Operating system before using any input pins for other devices.
