Very nice robot! Are the four ultrasonic sensors enough to cover all directions or are there some blind spots?
Also, it would be great if you can control the robot using a phone’s gyroscope sensor.

It depends on objects size, width and structure. I plan to use gyro.

I now can place my robots anywhere on earth and log in and control my robot from anywhere.
I do not need wifi for my robots.
I can connect directly to my phone IP address 
So it now work perfect in 3G and 4G network.
I am quite sure it also work on 5G network and will test it with a 5g phone in a 5G network as soon as I can.
In a 5G setup I can stream high resolution video from the phone on the robot and have almost no latency/delay/lag.
Anyone here want to log in to a robot in Peru and drive around at the inca sites or anywhere else ? 
If anyone have lots of LEGO Mindstorms or NXT or arduino or raspberry pi and have a large space for robots
I can explain how to set up your robots and then people from all over the world can log in and have a driva or a game or solve a problem with your robots.
There is similar games online.
One is in Kiev / Ukrain but it is probably not aktive now.

Sorry I could not understand one thing. What is exactly the function of the mobile phone attached to the robot’s body? Is the phone functioning as an IP camera? Also it looked like there are some Leds on the robot’s body which are blinking in synchronization with your voice. Is it really so or I am just thinking? Thank you.

The android phone is turned to a IP camera with the android app called RoboCam.
The LEGO Mindstorms EV3 have leds that is blinking when it is connected by bluetooth.
It is not in sync with my voice.

Thanks a lot for explaining. So, it is possible to use this robot for monitoring our homes when we are at office or somewhere else, isn’t it?

Yes.
Just build a 2 wheeled robot and tape an android phone on it with a installed google play app called robocam.
Then you need to open port in your router called port forward or open DMZ.
Google it or get back to me if you have problems.
