kernel. You can still create another boot loader entry for your older kernel. In the next example, the grub.conf file contains entries for two Linux kernels, one for the kernel installed with 7.2, 2.4.7-10, and one for a more recent kernel, 2.4.12. With GRUB, you only have to add a new entry for the new kernel. If you are using LILO, just add a new image segment for the new kernel in the /etc/lilo.conf file. Be sure to execute the lilo command to update LILO.

n the preceding chapters we had no xed destination for the robot to go to. The robot just moved around whether randomly, or following a line drawn on the oor, or around an object, but with no nal destination in mind. This kind of behavior has been useful in applications such as mowing or sweeping areas that the robot can visit. There are many applications where the robot will need to go from one point to another. It would be simple enough to make the robot go to a point, as you have seen in Chap. 4, if there are no obstacles in the way. However, if there are obstructions between the robot and its target destination it will become necessary for the robot to circumnavigate the obstructions while making headway toward the target. In this chapter, we will address two general methods for indicating to the robot where to go: Using a marker beacon that hangs over the target position. The robot can see and home in on this beacon. Giving the robot a GPS (global positioning system) unit and a compass along with destination coordinates so it can calculate a path to the target and follow it.

If your system requires certain modules to be loaded when you boot, you may have to create a RAM disk for them. For example, if you have a SCSI hard drive or CD-ROMs, the SCSI drivers for them are often held in modules that are loaded whenever you start up your system. These modules are stored in a RAM disk from which the startup process reads. If you create a new kernel that needs to load modules to start up, you must create a new RAM disk for those modules. When you create a new kernel, you also need to create its modules. You place the modules needed for startup, such as SCSI hard drive modules, in a new RAM disk. In the lilo.conf file, add an entry to load this RAM disk. You only need to create a new RAM disk if your kernel has to load modules at startup. If, for example, you use a SCSI hard drive, but you incorporated SCSI hard drive and CD-ROM support (including support for the specific model) directly into your kernel, you needn't set up a RAM disk. Support for IDE hard drives and CD-ROMs is already incorporated directly into the kernel. If you need to create a RAM disk, you can use the mkinitrd command to create a RAM disk image file or create a RAM disk device. See the Man pages for mkinitrd and RAM disk documentation for more details. mkinitrd takes as its arguments the name of the RAM disk image file and the kernel that the modules are taken from. In the following example, a RAM disk image called initrd-2.4.7-10.im is being created in the /boot directory using modules from the 2.4.7-10 kernel. The 2.4.7-10 kernel needs to already be installed on your system and its modules created.

Once the robot knows its path it will proceed toward the goal. When it encounters obstacles it will have to momentarily abandon progress toward its destination and deal with the obstruction. We will assume that there is at least one path that can lead from where the robot is to the goal position. We will deal with situations where there might be no path in

# mkinitrd /boot/initrd-2.4.7-10.img 2.4.7-10

In the lilo.conf segment for the new kernel, you would place an initrd entry specifying the new RAM disk.

Linux and Unix systems use the same standard underlying graphics utility known as the X Window System, also known as X or X11. This means that, in most cases, an X-based
