Well I got some free time while I finish my
obligation….for army. Yup it is a totally new start for my life. I can start to
think what should I suppose to do for next step. Before I make a decision, I will
finish my previous job…. a humanoid robot. Yes, I got all aluminum frame of the
humanoid robot. However there are many mistakes I made, such as difficult to
assemble, no space for the wire and the dimension of the humanoid robot. Well…it’s
my first to design it. That means there is still lots of room need to improve.
It is a little off topic. Let’s back to the topic.
Today I will integrate Raspberry Pi, MPU-6050
and Atmel-based controller. The idea is that RBpi is in charge of the image
processing, MPU-6050 for detecting the status of the robot including gyroscope
and accelerator and Atmel-based controller for managing 20 servos. As you see
in the picture, I made a tiny PCB board to put MPU-6050 connect to GPIO of the
RBpi. I also made two 5v power suppliers and a TTL port for communicating with
controller.
Now I put everything in the body frame of
the robot in below picture. It looks not bad. And my robot finally won’t fall
down…I hope :p So let’s test the MPU-6050 demo. Check out the youtube below. As
you see, I make a mistake which is that the direction of the pitch is opposite.
I will fix it next day.
