Autonomous Kit
The DFRobotShop Rover Autonomous Kit is intended to help you get started with autonomous control of a
mobile robot which uses sensor feedback. The kit includes the popular “IR compound eye” mounted atop a
simple servo-based pan/tilt system. The eye allows for simple motion tarcking and distance measurement (for
example maze solving and obstacle detection). The kit also includes a buzzer (which can produce simple tones
and auditory feedback) as well as encoders. An IO shield makes for easy connection, and the LiPo battery means
you don't need to invest in AA batteries.
Assembly Guide
 To assemble the DFRobotShop Rover base, please refer to the assembly video above for the Basic Kit.
 To assemble the IR compound eye and pan/tilt kit, please use the printed instructions included in the
package.
 To mount the encoders to the motors, refer to the encoder assembly video.
 We suggest mounting the buzzer to the upper left or right corner of the tilt bracket using the hardware
provided, leaving only two mounting points for the compound eye.
 The double-sided tape is suggested to fix the base rotate servo to the PCB, though the DFRobotShop
Rover Expansion Plate (sold separately) is suggested.
 As is shown in the main image, it is possible to mount the sensor bracket on top of the base rotate
servo, followed by the tilt bracket. Only two out of the four screws can be used. Be careful of the
wiring.
 The ribbon cable provided is to connect the IR compound eye as well as the Ultrasonic sensor to the IO
shield. The wires are intended to be separated.
Power
The Autonomous kit includes a rechargeable 3.7V 1000mAh LiPo battery. To charge the battery, ensure the
Li_Sel jumper located in position 2 on the DFRobotShop Rover PCB is in place, and connect a USB cable from
your computer to the board. Alternatively, you can use the included 4xAA battery pack, though the jumper
needs to be removed.
Motion
The DFRobotShop Rover Basic Kit uses two tank tracks, each connected to their own DC gear motor. Rotating
the tracks at the same time in the same direction produces forward motion. Rotating the tracks at the same
time in the opposite direction causes the robot to move in reverse. Varying the speed of one of the tracks will
cause the robot to move in a circle. Rotating the tracks in opposite directions causes the robot to turn clockwise
(or counter-clockwise) on itself (zero turning radius).
The kit includes a mini pan/tilt kit which can be used to mount the compound eye, the ultrasonic sensor, the
sensor bracket and the buzzer (individually or all together). The base rotate servo can be stuck to the PCB using
the double-sided tape, or usin the expansion plate sold separately.
