Electric Circuit#

On picture below you may see a block scheme depicting how Valera’s electric curcuit is composed. Please note that different versions of the robot uses different microcomputers. Valera v0.1 utilises microcomputer ODROID-N2L whereas Valera v0.2 utilises Orange PI 3B. Some images on this page are not updated to the new version of the robot, so if you see ‘Odroid’ on the picture - it means any microcomputer, Odroid or Orange PI, otherwise the difference should be stated in the text.

That’s how it looks in reality

Please watch the assembling process video or read a full instruction below.


Step 1#

Connect low current voltage converter, two wires and jack cable to the button form one side and XT60 wire from another side. Mind the polarity.

Step 9#

Connect the servo controller to the microcomputer using the SCL, SDA, and GND wires. The pinout is labeled on the controller. Both microcomputers has the same pinout, please see it below, but the pin colors differ for different microcomputers:

Step 10#

Connect the 6 servos to the servo controller using extension wires. Ensure that you connect the data cables to the correct data pins and pay attention to the polarity. Follow a logical order when connecting the motors to the servo controller. For instance, arrange them from top to bottom and left to right. The order would be as follows:

  1. Neck

  2. Left shoulder

  3. Right shoulder

  4. Left elbow

  5. Right elbow

  6. Robot base
