Android Gym Platform

More contents will be added soon~


Android gym platform is the our project of the embedded system contest held in Southeast University.

We used Allwinner Technology A20(Cortex-A7) based development board to make a gym platform prototype. This platfrom can use the RFID technology to achieve user identification. This platfrom can use the EMG sensor to monitor the musule exercise intensity and use the heart rate sensor to trace the hart rate. And there is a user interface to display all the parameters. And we recompiled the kernel to achieve the camera function. We want the gym member to record their exercise moments when they are working out.

We won the second prize in the contest.

This is the user interface. I can show the camera image and the user data.

Because the camera interface is not correct. So we made the PCB to convert the interface. And we also taught other groups this plan to solve the camera problem.

After the contest

After the contest, we want to do more on our gym platform. So, we designed a larger interface. We used the infrared touch screen combined a 20 inches screen. We used an another developer board (PINE64) and screen driver to build an equipment which can be mounted on the read fitness equipment.

This platform is a user interface between gym member and the fitness equipment. I can help trace the user exercise data and give the user instructions.

We also designed a software prototype. This is my first time to design a software.
