Step by Setp Assemby of the Bluetooth module on Robobuilder

[PedroR]

Hi all

As I had previously mentioned, I also got a BT module for Robobuilder myself and decided to document the process.
(The original instructions of the manufacturer can be found here http://robosavvy.com/RoboSavvyPages/Rob ... ctions.pdf)

Here are the pics of my experience:

Step 1: Open the RBC box


Step 2: Removing the top part to expose the battery.

The battery seems to be glued to the plastic box so I just disconnected the battery cable to release the top.

This is one of the sides of the PCB, before inserting the headers for the BT module.
Just FYI, the screwdriver that's included in the Robobuilder kit is not appropriate for removing the small screws that secure the PCB. This same model of screws is also used in the Robobuilder head.
I don't really know the reason why they chose to do this. All other parts of Robobuilder can be assembled and disassembled with the included screwdriver.


Here is the other side:


Step 3: Inserting the headers for Bluetooth.
Please note you need to insert the 3 pin header in the right position to avoid connecting the RESET pin of the BT module.


Step 4: The soldering
I am not proud of my soldering but it works, so I'm happy for my achievement!


Step 5: Inserting the BT module into the headers


Step 6: The board, connected to the battery for testing and ready to be assembled back into the box


I must say it works very well and I've been having a lot of fun controlling it wirelessly using the software available here http://robosavvy.com/forum/viewtopic.php?t=3269 and the karate motion files that are here http://robosavvy.com/forum/viewtopic.php?t=3301

I intend to post a video on that soon

Hi there,

could you tell me if we could change the baudrate and what is the latency of the communication ?

Thx
