Cannot access the gesture control in the web server

Hi,
I tried to access the gesture control in the web server, but it did not show anything. In the terminal that I used to start the robot, it showed those lines

AttributeError: 'SequenceRobot' object has no attribute 'get_time_sequences'

The robot work fine with all of the video example, it just show those errors whenever I clicked on the "Gesture Control"
Finally, I am using VMWare to run the code in Linux.

Thank you,

Pushed the missing functions, they should work now

Sorry for the late update. I just try it again and there is a few things happen

1. there are no errors shows up in my terminal
2. the web browser is just a black page, there is no windows or anythings. (This is different than before you updated the code. Before it, I saw two windows in the browser, but there is no items in those windows)

Try running yarn install in the blossom_web directory?

Hi,
I did run the yarn install. I think that I have not explained my problem clearly.
When I run this line of code python start.py -n woody.

• A new tab pop-up in my browser.
• I could see the six videos, and when I click on the video, the robot reacted to the video.
• When I want to create new action and click on the "Go to gesture control", all I see is the black space, which is different than before.

This is the versions of the software that I used, in case you want to know, Node 8.11.3, Yarn 1.9.2, Python 2.7.15, and Anacondo instead of virtualenv

Thank you,
~Duy

Edited: additionally, I tried it in both Firefox and Chrome.

I'm running similar versions, apart from a slightly newer version of Node (10.7).

You can't create new movements in Gesture Control, it's only there for playing gestures similar to typing them in the command line interface.

I added the code for the Expo application so that you can control the robot using the phone and make / record new gestures:

I downloaded the new code and tried to run it.
Every time I turned the "Control Robot" on, I got this error on my terminal:

Additionally, would you mind make a quick tutorial video on how to use the app? I only saw controlling button for the height and ears of the robot. I would love to learn how to control the other DOF of the robot.

Thank you

Pushed updates to the control files; I'm currently out of town so I don't have an actual robot to test with but it seems to not throw errors testing just the app connected to the server.

To control the robot with the app, just move the phone around (screen up, with top of the screen pointing in the same direction as the front of the head so the robot should be facing away from you) and the head should follow the movements. The height and ears are controlled with the sliders. Press 'Reset Height' until the head and phone are aligned. You can also turn on 'Mirror' under 'Settings' to make it easier to control with the robot facing you instead of away.
