Modify your OpMode to add the motor related code. For now your completed servo code can be dragged to the side of your work space. You may alternatively choose to create a second program.
Just like servos, a motor is a form of actuator. You may picture a dozen different things when you think of a motor, from those used to spin the wheels of a car to the large turbines that allow a plane to fly. For our robots, we will be focusing on DC motors. These are a type of electrical motor that use direct current, or DC, to rotate and produce the mechanical force needed to move an attached mechanism.
Most standard motors are able to continuously rotate in either direction with an adjustable speed or power. Some motors may also include a built in encoder, which allows them to move to a specified position, similar to a servo, or to collect data like the number of completed rotations!
To access the motor snippets in Blocks we need to look under the Actuators dropdown menu:
You may notice there are several options for blocks under the DcMotor menu. For Hello Robot we will be using those found in the DcMotor menu itself and under Dual.
In the next few sections, we will be learning to program our motor to first move automatically in different directions then in response to our gamepad inputs. In our final section we will take a look at using telemetry with our motor's built in encoder.
Below is a sneak peek of our final full code:
As the name suggests, the blocks found under Dual are intended for the use of two motors. We will learn more about them in !
If you do not see the DcMotor menu under Actuators double check your includes a motor and is currently active on the Driver Hub!
