The robot

Here are some photos of Svbot.


As it is showed in the pictures the robot is made with Lego and it has a shoulder, elbow and a hand. The elbow and the hand are moved by two CC motors situated on the back of the arm. The CC motor that moves the shoulder is situated on the base of the robot. To move the wheels there are two stepper motors situated on the bottom of the basis. There is also a CC motor that moves a camera in the arm. Anyway the electronics to transmit the video signal is not placed on the robot yet.



To have a feedback about the arm position there are placed two potentiometers on the axles that move the shoulder and the elbow. On this way, using and analogue-digital converter is possible to know the arm position. Regarding the hand, there are an encoder and an end carrier sensor. To know the position the software will have to count pulses and store the value in the eeprom.




In the next chapter I'll write about the electronics.
