Two days ago, we finally managed to flash the Gainspan Wi-fi module’s firmware and we can now talk to the module through the SPI interface and I managed to make it connect on a router which was in the room. I am now working on the driver to make it work completely.
As I had finished coding the PD algorithm, Pierre-Hugues worked in order to enable us making real tests of balance with Ball-E. Therefore, I build a system to put the robot on the ball while hanging in the air so that it couldn’t fall on the floor (you may see it on the pictures). We made some tests with several balls and it appeared that we needed to have a center of gravity higher. That’s why you can now see Ball-E with a tall structure. Today we are going to buy a bigger ball to make new tests, it should be easier for the robot to keep its balance with this one.
We hope that in a few days, we will post videos of Ball-E standing up and not falling !
