Why enable_servos() and disable_servos() should not be used on the CBCv2

NOTE: This article probably does not apply to the new Link controller.

Older KIPR documentation states that enable_servos() is used to turn on the CBC's servo controller, and disable_servos() is used to turn it off. This has been outdated since the CBCv2 came out in 2010, and I do not recommend this anymore for the CBCv2.

The Random Function Library - mrp & bmd - Simple

mrp (move relative position) is a function that will move a motor for a set distance at a set speed. This is probably the simplest way to move a lego robot. mrp starts a motor moving. The motor will stop after the wanted distance is achieved, but the CBC will continue going through the program unless you put a bmd.

Earthquakes and Engineering: Their special connection

Earthquakes, they are really common here in California. What does it have to do with engineering? One cannot realize this, but the way that homes are built in California solely rests on how much a build can resists enough shaking before it falls down to the ground and turn into rubble. Furthermore, it also depends on what type of soil, and how good or flimsy a structure it.

Music and Engineering:Are they like oil and water?

According to my dad, most engineers are photographers and doctors are musicians. Is that true? Because of what I have seen today, musicians can be engineers.Please leave your opinions in the comments area.

1 The Necessity of Discovering Information from Other Regions

Off Season Botball preperation game

This is a game I created for teams to possibly do during the off season this summer/fall.

The game uses the field materials from last years game which keeps the costs to a minimum.

This is a great beginners game to introduce new members to the Botball experience.

iPhone Create Controller - The project that never quite got released

Hello Botball community! My name is Alexander Nabavi-Noori, and I was an acting YAC member last year. Today I am here to release into the wild a really cool project that I, and my friend James Linnell worked on in our spare time last year. Its called the iPhone Create Controller. This was going to be a paper we were going to submit, but as all engineers know: shift happens.

Lego Botguy Replica Instructions for Team Trophys

Here are pdf instructions on how to make a Lego Botguy replica.

This is a cheap little trophy that can be given out to all of the team members at the end of the season.

The cost of Lego's per Botguy is around $9 if you have no Lego's on hand.

It took approximately 2 hours to design Botguy on Lego Digital Design and build him.
