zugaldia / android-robocar Goto Github PK

I got a bunch of build error in three modules: libcv, libhardware, and libsoftware. It is the same error in all three, and it looks something like this:

robocar\libhardware\src\androidTest\java\com\zugaldia\robocar\hardware\ExampleInstrumentedTest.java:4: error: package android.support.test does not exist
import android.support.test.InstrumentationRegistry;

The solution that worked for me was to add the following to all three build.gradle files of the above mentioned modules under the dependencies sections

 androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

At the end of http://www.androidrobocar.com/pages/hardware, the link to continue reading points to http://www.androidrobocar.com/pages/pages/build, and I get a 404 error.

Currently we're hardcoding values, like the Bluetooth MAC address, which developer should be able to customize.

We have a fancy new domain (http://www.androidrobocar.com) that we could host here on GitHub, but there's no content yet. Let's build a basic website.

We're currently taking one picture every second, we should take pics more often. For that, we need to keep the camera session open between shots.

Android Things can use a standard speaker to talk to the Robocar user. We'd like to build the following:

• A generic interface that could be implemented by third-party providers (AWS Polly, Google Speech API...).
• A default implementation using core Android's TTS.

Thanks for this code. But, after opening app in device
screen shows searching for robocar. Please guide us..

Let's use the wiki (https://github.com/zugaldia/android-robocar/wiki) to have the basics covered, for example, how to build a basic robocar from scratch and install the demo app on it.

Hi, I'm having trouble building both the mobile and robocar apps, the build project went OK but when trying to run "app", it has the following error in Android Studio. Appreciate your help!

Information:Gradle tasks [:app:assembleDebug]
Error:Execution failed for task ':app:transformNativeLibsWithMergeJniLibsForDebug'.

We should either use the mobile app or the NES30 Pro to set more fine-grained speeds. This would improve the quality of the input we'll provide to TensorFlow. Currently, we only move forward at either 255 or 95 speed.

I'd love to see LIDAR support for the Robocar eventually.

The device from http://scanse.io seems like a developer and budget friendly option that we could start with. It has an open source SDK (https://github.com/scanse/sweep-sdk) and comes with a dummy libsweep.so file that always returns static point cloud data and does not need a hardware device. This allows starting to hack on it quickly, and once you have a device just switch out the libsweep.so lib.

As mentioned on Wikipedia,

If both the wheels are driven in the same direction and speed, the robot will go in a straight line. If both wheels are turned with equal speed in opposite directions, as is clear from the diagram shown, the robot will rotate about the central point of the axis

You are currently only turning on one side of the wheels to turn instead of reversing the other side.

We've added checkstyle support, but we aren't using it during the CI flow.
