## RVR Sphero Mini-Robot # RVR Sphero
### sphero_rvr ## Sphero RVR
This ros modules contain an experimental ROS Node for the Sphero RVR.
It is based on Rud Merriam's "RVR CPP" (see rvr++ folder) and
running on a Jetson Nano 2GB running a minimal Ubuntu 20.04.
Currently a very rough base_controller that responds to cmd_vel/Twist. This ros modules contain an experimental ROS Node for the Sphero RVR.
The cpp version is based on Rud Merriam's "RVR CPP" (see sphero_rvr_hw/src/base_controller.cpp). The python(3) version is based on the official Sphero RVR Pyhton SDK (see sphero_rvr_hw/scripts/
Both version use /cmd_vel and publish to odom.
There is still no real ros_control package (the stubs are already there - see sphero_rvr_hw/src/sphero_rvr_*).
### Lynxmotion 4DoF arm ### Startup
To run the python version:
- source ~/minibot/catkin_ws/devel.setup.bash
- start a roscore
- python3 ~/minibot/catkin_ws/src/sphero_rvr/spehro_rvr_hw/scripts/
To run the cpp version
- source ~/minibot/catkin_ws/devel.setup.bash
- catkin build
- roslaunch sphero_rvr_hw rvr_ros.launch
