For example, Stanford’s Junior uses two quad core computers as a cluster to support all the

computation. As the performance of computers has evolved a lot, now we only use a single personal

computer, and possibly migrate the software platform into high-end smartphones. In this case, we

have to simplify some existed algorithms to deduct some calculation task and still re main the basic

functionality. Even we lose some accuracy, we can still make sur e that our system is safe and eﬃci ent

enough for passengers .

In addition, we only use cheap sensors. For instance, the vid eo cameras are low-end webcams

and cameras in smartphones rather than high-end professional cameras. Thus, the deﬁnition of our

sensors is lower and the responding time may be longer. So we have to use multiple sensors to reach

redundancy for robu s tn es s .

3.6 Conclusion

Autonomous driving has always been humans’ dre am. Although this task is hard, ther e are

already some signiﬁcant app r oaches. For most automakers, they are aiming to make automatic and

manual mix ed system, because it is more mature to make a proﬁt. For technical companies and

research institutions, they utilize the most advanced har dware and technologies to reach the best

result as t he y can. Our project do es care about short-term proﬁtability so that we us e low-cost

sensors and computers to make a fully automated car. If we make a success, there would be a big

potential market, and humans’ life will improve a lot. However, there is still a long way to ﬁnally

ﬁnish our prototype and then make it into the market.
