A Look at a Project
Following is information about the third project presented in Competitive MINDSTORMS: Zip-Bam-Bot
Version XK2 (see Figure 1-1). As its name implies, there is more than one version of the Zip-Bam-Bot
design. There is XK1, XK2, and XK3, of which the first two are covered in Part Two of

MINDSTORMS are in gray
scale and do not have a

elements are included in

site only for illustrative

We'll begin by examining the construction of XK2. First, there is the chassis (see Figure 1-2); this
chassis is featured in Chapter 3 of
Competitive MINDSTORMS with complete building instructions.
Then there are three subassemblies for XK2: the head subassembly (see Figure 1-3), back skid
subassembly (see Figure 1-4), and the light sensor subassembly (see Figure 1-5). Each of these
subassemblies are attached in a final assembly section with additional pieces, including two touch
sensors. And, of course, there are complete building instructions for everything.

Once everything has been attached and the sumo-bot's construction has been completed,
programming commences.
Competitive MINDSTORMS uses the NQC programming language, created
by Dave Baum and now maintained by John Hansen, and the BricxCC IDE to program all the
sumo-bots. Complete descriptions of all the programs and how to run them are given, and instructions
on how to obtain these (free) programming tools are given as well. How to download programs to the
RCX microcomputer is detailed in a section in Chapter 3.
