since i am newbie and i am going to ask simple questions any help will be appreciated.
i have a project where i have to create maze solving robot using "Left Hand Rule" , i bought the component and finished the assembling ,
( 3 ultrasonic sensors HC-SR04 , 4 wheel robot )
i have a serious problem is the robot after a complete 5 ends ( solve the maze 5 times ) it kind of start moving slowly
my connection is like that
3 battery of ( 3.7V , 3800MAH) connected Sequentially forming ( 11.1 V ) connected directly to L298N dc drive and the 5+V I/O from L298N goes to the arduino Vin
my question :
- is the slow of the robot movement after X no. of times normal ? if yes , how could i prevent that ?
- does the ultrasonic take a lot of power ?
