17 [build the challenge-bot](http://goo.gl/XgB0xq)
21 Most introductory robots are "dead-end" robots that
22 tend to strand people after they have the first
23 few robot behaviors implemented -- obstacle avoid,
24 wall follow, stay on table, etc.
26 One of the primary goals of the challenge-bot is to try
27 to make it expandable from simple to more complex in
28 reasonable incremental steps.
30 The base is organized around 1-inch x 1-inch grid peg-board
31 which is readily available from locations such as Home
32 Depot, Lowes, and lumber stores.
