Research #10

I have design the base for the robot structure out from the paper.

The figure below is the one that I have designed as a part  base will be the leg for the four-legged robot which supported each leg by 2 servos.

 Next, I will combine all the part with the servo motors and we shall see the assembling results on next week.

Design Printed Circuit Board (PCB) using Proteus

Function this Circuit to use for Servo Controller  SC08A. input for Lippo Baterry is 7.2V 1800mAh and output for this circuit is 5V 3000mAh. if we used normal regulator the output current only 1000mAh but if we use IC regulator 78T05 the output is 3000mAh. for SC08A the max input voltage is 6.4V so we need to step down the voltage and maintain the current output.

Research #8

As I mention previously, the infrared sensor is to detect the obstacle when the robot start to walk and it will send a message to the motor to move the robot as to avoid from any obstacle ahead.
