Kinematics functions of the Aleph 0 Rover. The logic is a little bit mixed up. This class should only compute the kinematics, but it also is used to publish messages to ROS.

danielsnider / set_robot_as_ROS_master.sh
Last active August 26, 2017 17:43
Team R3 has developed a script to automatically set your ROS_IP environment variable and to detect an online robot using ping and set your ROS_MASTER_URI environment variable (assumes a static IP for your robot). If your robot is not online your own ROS_IP will be used in your ROS_MASTER_URI. To use this script run 'source ~/set_robot_as_ROS_mas…
#!/bin/bash
# Get my IP
MY_IP=$(hostname -I | grep 192.168.137 | cut -f1 -d' ')
exit_status=$?
if [ $exit_status -eq 1 ]; then
echo "ERROR: you do not have an IP on the robot network (192.168.137.x). Please set one. Aborting..."
return 1
