The Way To A Humanoid Robot (1)

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.
