Mesh Robot - ViVi

A WiFi mesh network based robot, which controlled by phone and is programmable.

Similar projects worth following
ViVi is a Robot developed by DOIT, in Shenzhen, China. ESP8266 is utilized as MCU for ViVi. We developed a Mesh network library for this robot, so several robots can construct a Mesh network automatically when they power up. Messages or commands can be broadcast to each robot in this Mesh network. What's more, you can send messages (commands) to one or more specified robot(s) in the Mesh. We use phone (Android and iPhone/iPad are both support) as controller. You can control all the robots in the Mesh at the same time by sending commands from ViVi App on your phone.

Each robot plays as a node in the Mesh. When new robot power up, he will join the Mesh he found automatically as a new node, and then
he can receive message from other node in the Mesh.

Features:
* ESP8266 inside, support STA+AP mode, 4MB flash size, utilizing SPIFFS
* Mesh network supported
* Provide App for both Android and iOS devices
* Lowcost
* Open source (App excluded), fit for Geeker

Dear Wang 

It is perfect robot, but I have some questions. I want to buy vivi board,but I wonder if it is controlled by arduino joystick shield wirless(nrf module). I have looked at board and I noticed a connection Rx TX for programming pins. So Can I plug in a nrf24 it . So Can I  make WiFi Communication between  robot and joystick. I will write software.

  Are you sure? yes | no

I have read about this case before , so I have bought new battery and fully charge out of the robot and connect them after charged. They still acting the same as I have mention.  I thought may  be , I will buy new control board and test. what you think? that will be solve the problem or not? Thanks and best regards.

@tossaporn.tik  Hi, can you provide the link you bought this robot? Maybe you can send it back to the seller. If you bought the robot from the links we provided as we mention above, we will be able to receive your robot and then solve the problem for you. Thanks.

Dear Sir

I have bought Vivi robot from Aliexpress, I have control the robot with android mobile phone.But they always disconnected even we have test with many mobile phone.
And sometime they can work ,when we push bow ,the robot operate and fall down. If we control the step forward  continuous they hang out and disconnected. Sometime , when we start the robot push on the switch all the servo twist. I need your help suggest what to do , this happen cause of hardware (board) or software?

@tossaporn.tik Hi, I think the problem is that your battery has not enough power. I faced the issue before. When power is not enough, the robot will not act as normal.
