$ roslaunch simple_drive drive_teleop.launch joy_dev:=/dev/input/js0 The button mapping was tested on an Xbox 360 controller and should require little or no modification for similar controllers. Typically the servo is used to move a camera so that the teleoperator can look around the robot. This node simply sends commands to other nodes. This node converts sensor_msgs/Joy messages from the joy node into a variety of commands to drive the robot at low, medium, and high speed, look around with a servo, and cancel move_base goals at any moment. This diagram is also available in Visio format. The microcontroller must also be connected to the computer running the simple_drive ROS node by a serial connection (ex.

Install the drive_firmware onto a microcontroller connected to motors and wheels by PWM. $ roslaunch simple_drive simple_drive.launch serial_dev:=/dev/ttyACM0ģ. $ roslaunch simple_drive cmd_vel_mux.launch Launch ROS nodes: $ roslaunch simple_drive drive_teleop.launch joy_dev:=/dev/input/js0 $ sudo apt-get install ros-kinetic-simple-driveĢ. Package created by Ryerson University students for the University Rover Competition, summer 2017. Microcontroller software that controls your motors. Send motor commands to your microcontroller. Motor commands from multiple sources are forwarded with a preference for human control over autonomous commands. Left joystick thumbstick controls left wheels, right thumbstick controls right wheels.
