student finally question car relay

Jane Medium ： According to the students' questions , This paper combs the problem of double car relay in Sancha road in detail , Help students understand the relay process at the three fork road .

` key word ` The smart car race , Two car relay , A fork in the road

# §01 3、 ... and Switch relay

Question 1 ： What is the definition of the no ball relay of the two car group ？ It's in the Trident area , A car stopped , Does the other car start ？ Or the front car, pat the rear car's ass , Then the rear car starts ？

`▲ chart 1.1 Pat your ass for a no ball relay `

`▲ chart 1.2 Double fork Ballless relay mode `

Question two ： What is the definition of three differences in completion ？ Because the trident of the original rule is one in and one out , It is divided into three forks and three forks . If a four wheeled vehicle has just entered the Trident , Then it's three minutes , Is it a score ？ There is also a double car set. The catch car must be placed in the Trident at the beginning , How does this count ？

Question 3 ： How is Trident calculated for a double car set ？
If two cars are taken as a whole , Two times before and after the Trident is really no direction , But if you look at only one car, the tricycle only goes on the three pronged road , The upright car has to get off the road , Is this a trident ？

If possible , Could you please give us a detailed description of the double car Trident

## One 、 The first question is

First , The relay with the ball must be in the same fork ,“ Pat your ass ” Finish the relay .

For the no ball relay , The following three relay modes are allowed ：

• At the same fork ,“ Pat your ass ” Relay mode ;
• At the same fork , One in one out relay mode ;
• At different turnouts , One in one out relay mode ;

With the ball relay 10 branch ; The no ball relay is 5 branch ; Plus the completion of the entrance and exit fork , You can have 5 branch ;

Two models are not allowed to run at the same time during the competition . The boundary line of the Trident intersection is taken as the standard for the model to enter and exit the Trident .

If it's just a bike passing through a fork in the road , No relay process , Can only get 5 branch ;

## Two 、 The second question is

To complete a trident passing, a model car needs to enter the Trident intersection , A model car drove out of a fork in the road . If it's game time （ Like three minutes ） A car model just enters three intersections , The other car hasn't left yet , I think this Trident is not successful .

At the beginning , A car stands at a fork in the road waiting for the ball . As long as the first serve car drives into a fork in the road , When the receiving car drives out of the three fork road, it can complete a ball relay process , have to 15 branch （10 There is a ball relay +5 Three forks ）.

## 3、 ... and 、 Third question

For two cars , There are three modes for crossing a fork in the road ：

• Pattern 1： Both cars pass through a fork in the road , Finish the ball relay , score 15 branch ;
• Pattern 2： Both models cross a fork in the road , Finish the no ball relay , score 10 branch ;
• Pattern 2： The two cars pass through the two sides of the fork in the road , Finish the no ball relay , score 10 branch ;
• Pattern 3： A model car stopped at a fork in the road , Another car passed the other side of the fork in the road ; score 5 branch .

therefore , What you said if the two cars are taken as a whole , Two times before and after the Trident is really no direction , But if you look at only one car, the tricycle only goes on the three pronged road , The upright car has to get off the road , It's normal to cross the trigeminal intersection .

# §03 repair Fill the regulations

At the beginning Track design of the 16th smart car competition finals online race The regulations for two car competition need to be supplemented . The rules that need to be improved are ：

• The two car relay must complete a ball relay in the competition , Or no ball relay ;
• Double car relay allows multiple ball relay , The relay ball is passed from the moving model to the stationary model ; Completing the multi ball relay allows the model to carry multiple balls , Or use mechanical means to move the ball from back to front ;
• The course of the game , Both cars must be on the track , Only one car is running . If a car rushes off the track , Then you're not integrating . Unless the car model out of the track returns to the track .

# ※ ask Summary of questions ※

In fact, the rules are not absolutely perfect , Only the questions asked by the students The more , The rules can be more perfect .

I hope to use your question , This document can form the detailed rules of the two car race .
