Exercise 7.2 7 The Hybrid Deliberative/Reactive Paradigm
Decide whether each of the following is deliberative or behavioral: path planning,
resource allocation, map making, avoiding obstacles, navigation.

Exercise 7.3
Name and evaluate the following architectures in terms of support for modularity,
niche targetability, ease of portability to other domains, robustness.

a. AuRA
b. SFX
c. 3T
d. Saphira
e. TCA

Exercise 7.4
Why do behavioral management and performance monitoring require global know-
ledge?

Exercise 7.5
How does the Hybrid Paradigm address the frame problem and the open world?
Exercise 7.6
List the five basic components of a Hybrid architecture.

Exercise 7.7
Describe the difference between managerial, state hierarchy, and model-oriented styles
of Hybrid architectures and give one example of each.

Exercise 7.8
Describe the use of state (Past, Present, Future) to define behaviors and deliberative
responsibilities in a state-hierarchy architecture.

Exercise 7.9 [Advanced Reading]
Search for technical papers on Cog, Rodney Brooks’ controversial humanoid robot
project. What paradigm best describes the architecture and why?
Exercise 7.10 [Advanced Reading]
Look up technical reports on Shakey. Compare Shakey with the Hybrid architectures.
Now consider the possible impact of the radical increases in processing power since
the 1960’s. Do you agree or disagree with the statement that Shakey would be as
capable as any Hybrid if it were built today? Justify your answer. (This question was
posed by Tom Garvey of SRI.)
