iURIS - Being Independent

After everything was finalized, many designs were thought for iURIS and implemented. 3D files for iURIS were designed using Autodesk. They were 3D printed and assembled. Casing for each component was carefully designed keeping in mind the user's comfort. Also the Li-ion Battery was chosen due to its consistency and better life. The 3D printed product is uploaded.

Till now every test we performed was wired and the device was powered through a laptop. However, this was uncomfortable and there was a need for making the device wireless. We selected HC-05 bluetooth module to add the wireless feature on our device. HC-05 transmitted the x and y co-ordinates obtained from Arduino Pro Micro. Another HC-05 received these co-ordinates and fed it to another Arduino Pro Micro connected to the target device (computer or mobile phone). The first Arduino Pro Micro was used only for processing of x and y co-ordinates where as the second Arduino Pro Micro acted as the HID compatible device.

After properly applying filters to MPU6050, Arduino based Pro Micro was studied. Pro Micro was selected for this because of its HID compatibility. It can act as external mouse as well as keyboard for any computer or mobile phone. The HID compatibility of Arduino Pro Micro was implemented and tested to get reliable results.

MPU6050 was studied and the data obtained from it was analyzed. Application of Kalman and complementary Filters was implemented on the raw readings. With some changes in the formulas for Kalman and complementary filters, thee raw readings were onverted in the for of x and y co-ordinates.
