Hello, I am a newbie here, my first robot design. I have made a robot( Arduino Uno R3 ATmega328P+ motor shield L293D+2 IR sensors+ 4 DC 3-6V Motors+ultrasonic sensor+9v Battery+ servomotor SG90) Schematics: Imgur: The magic of the Internet instead of that power supply I got an Duracell Basic, 9V, Al…

Thanks a lot Tom! What if I connect 2 batteries like those in the image in parallel? Should this make enough power? Or should I change the power source?

Hi, Change power source. What are your motor and servo specifications? Tom... :grinning: :+1: :coffee: :australia:

SERVO MOTOR: Weight: 9 g • Dimension: 22.2 x 11.8 x 31 mm approx. • Stall torque: 1.8 kgf·cm • Operating speed: 0.1 s/60 degree • Operating voltage: 4.8 V (~5V) • Dead band width: 10 μs • Temperature range: 0 ºC – 55 º 4 DC MOTORS: Voltage:3-6V Torque 0.8kg*cm RPM: 3V:125rpm, 5V:200rpm, …

Hi, Try 9V worth of AA 1.5V batteries in series. That is 6 batteries in series. Tom.... :grinning: :+1: :coffee: :australia:

Thanks a lot for your help Tom! Have a good day!
