Test: The LEGO Mindstorms Quiz
Category: Robotics
Description: This test determines your knowledge of all things LEGO Mindstorms (RCX/NXT)
To compute "gear ratio" you must:
Divide the number of teeth in the drive gear by the number of teeth in the driven gear
Multiply the number of teeth in the drive gear by the number of teeth in the driven gear
Add the total number of teeth in all gears in the system and multiply by 3.14 (pi)
Divide the number of gears by the number of axles in the geared system
At which University was the LEGO RCX platform invented?
MIT
RPI
Harvard
Cornell
An RCX touch sensor is triggered by:
The simple press of a button
Detection of g-forces by its accelerometer
The closing of a circuit when a cross beam is lifted
The RCX kit does not have touch sensors
The RCX requires 6 AA batteries while the NXT requires only 4 AA batteries.
True
False
NQC is:
"Not Quite C" programming language for the RCX
The beta version of the NXT
A graphical toolkit for programming the NXT
A common error message displayed on the RCX
The NXT supports Bluetooth.
True
False
The NXT sound sensor has been designed to only be able to detect sounds which are in the audible range of humans.
True
False
lejos supports recursion, multi-threading and synchronization.
True
False
The NXT firmware has been "open sourced" by LEGO.
True
False
lejos is:
A LEGO competitor that makes high quality sensors
Java for RCX and NXT bricks
A proprietary programming model used in most of Europe
A large gear box used in robotics competitions
The main difference between the light sensor in the RCX kit and the NXT kit is that the NXT light sensor has the ability to "see" in color.
True
False
The NXT came out before the RCX.
True
False
Generally, which is more compatible with traditional LEGO pieces?
RCX
NXT
The motors that come with the RCX kit are 'geared-down' by LEGO.
True
False
A LEGO Mindstorm robot must be remote controlled.
True
False
Which of the following is NOT an official LEGO Mindstorm sensor?
Compass
Temperature
Sound
Humidity
The NXT motors have a built-in rotation sensor.
True
False
The NXT ultrasonic sensor can be used for:
Determining proximity to objects
Building an in memory picture using infrared
Listening to other NXT audio signatures
Linking two NXT bricks together on a common carrier frequency
In March of 2007, the WiigoBot:
Was featured on G4TV's Attack of the Show
Bowled a perfect game on the Nintendo Wii
Was blogged on gizmodo and engadget
All of the above
To increase speed and reduce torque you would:
Use a larger drive gear coupled to smaller driven gear
Use two large gears with a worm drive
Cross-pin an axle transmission with an overhead gearbox
Use a small drive gear coupled to larger driven gear
The difference between the RCX 1.0 and the RCX 2.0 is:
For the RCX 2.0 a power adapter was added
The RCX 1.0 had a power adapter
A USB 2.0 interface was added to the RCX brick for the RCX 2.0
There is no difference, it was a marketing trick
In which year was the LEGO Mindstorm RCX released?
1990
1988
1995
1998
NXT-G is:
The next generation of LEGO Mindstorm currently under development
The official revision of the NXT that is in production
An NXT-only (g) shock sensor
A graphical programming environment for the NXT
