This shield makes it easy to build an Arduino-controlled Zumo robot. The shield mounts onto an assembled Zumo chassis, connecting directly to the chassis s battery terminals and motors, and the Arduino plugs into the shield, face down. The shield includes dual motor drivers, a buzzer for playing simple sounds and music, a user pushbutton, and a 3-axis accelerometer and compass. It boosts the battery voltage to power the Arduino, and it breaks out the Arduino I/O lines, reset button, and user LED for convenient access and to accommodate additional sensors for things like obstacle and edge detection.
This 1.46″ x 0.79″ x 0.79″ gearmotor is a brushed DC motor with 120: 1 metal gearbox that has the power to deliver both speed and torque. These units have a 0.276″-long, 4 mm-diameter D-shaped output shaft.
This motor driver shield can drive up to 4 DC motor with 2 servo motors or 2 stepper motors with 2 servo motors. This motor driver shield uses 2x L293D motor controller chip with a 74HC595 shift register for all of its functions.
You can read this wire with an analog input such as those on an Arduino, to get the servo’s position. That information can be used in robotics to improve stability or even allow ‘recording’ of servo motion. The dimensions of this analog feedback motor are 11.57 x 22.75 x 29.45mm. The operating voltage for this motor ranges between 4.8 to 6V. Servo horns and associated hardware are also included in the package.
This 1.46″ x 0.79″ x 0.79″ gearmotor is a brushed DC motor with 65: 1 metal gearbox that has the power to deliver both speed and torque. These units have a 0.276″-long, 4 mm-diameter D-shaped output shaft.
