A Review: The LEGO Adventure Book: Robots, Planes, Cities, & More...


     The LEGO Adventure Book: Robots, Planes, Cities, & More. by Megan H. Rothrock, is the third book in the series. When volume 2 left off, The Destructor had been caught and was off to jail leaving the world’s AFOLs (Adult Fans of LEGO) safe to continue to create…

Oh no, he’s escaped!

     Once again Megan Rothrock, Meg, takes us on another adventure with the storyline written in text bubbles with cartoon LEGO characters as she is in pursuit of
“The Destructor” and along the way she introduces the reader to some of the world’s amazing LEGO builders. The featured builders are seriously talented AFOLs from all walks of life - a Postman, a Science teacher, Aircraft Parts Manager, IT Developers, Police Constable, and a Historic Preservation Advisor. A mini profile, with a custom minifigure, is given for each builder with web links showcasing their models.
     As in the previous books, Rothrock features some awesome models with amazing details. There are 40 step-by-step breakdowns on how to build the models such as a classic movie theater, an ice cream truck, and even sushi, plus nearly 150 example models in full color. Also, included are building tips from the builders themselves.
     The LEGO Adventure Book: Robots, Planes, Cities, & More. (Vol. 3) by Megan H. Rothrock, No Starch Press 2015, is another great read to add to your LEGO book collection. With the purchase of a printed book , come a free eBook. It may also be purchased at Amazon

     Of course, our heroine catches up with Destructor and he is captured, again… but wait, what is this???

FLL - Trash Trek: Ultrasonic vs. IR Sensor...

As you may know, sometimes the FLL field mat does not quite fit properly on the recommended tabletop. So, in this year’s rules it is stated that, “Slide and align it so that there is no gap between the South edge of the Mat and the South Border Wall, then center the Mat east-west, with equal gaps at left and right.”

With the mat flush against the South Border Wall, a team may be able to use an Ultrasonic or IR Sensor accurately to detect the South Border Wall. 

So, this became a test challenge for the members of the Brics~2~Bots Academy. Brandon assisted in the tests by designing a test robot, writing programs in NXY-G and EV3 to test the NXT Ultrasonic sensor (on an EV3 brick), EV3 Ultrasonic, and an EV3 IR Sensor. We made a chart to record the results.

Using:
EV3 brick and software, at Power Levels 20-75, measuring a stopping distance of 10 centimeters


Trials
NXT Ultrasonic
EV3 Ultrasonic
(less than or equall to)
EV3 IR Sensor -Proximity
(measure in Centimeters)
(equal to)
1
5.5 centimeters - 20 power 10 centimeters - 20 power 10 centimeters - 20 power
2
5.5 centimeters - 30 power 10 centimeters - 30 power 10 centimeters - 30 power
3
2.5 centimeters - 40 power 10 centimeters - 40 power 10 centimeters - 40 power
4
2.5 centimeters - 50 power 10 centimeters - 500 power 10 centimeters - 500 power
5
3.5 centimeters - 75 power 10 centimeters - 75 power 10 centimeters - 75 power




Conclusions:

NXT Ultrasonic - Seems to work with the EV3, but the response time is off. Measuring for 10 centimeters, it stops much closer and at different distances for the different power levels. See chart. This may be because the response time for the NXT Ultrasonic is slower than the EV3 sensor.

Ev3 Ultrasonic - AT powers 20-75 the EV3 stops accurately. Since the Ultrasonic senses a sound wave that is reflected out to the object; one might wonder, if surrounding sound would have an effect? Testing under noisy conditions didn’t seem to effect the performance of the EV3 Ultrasonic. However, at the  NYC FLL finals at the Javits Center, the noise level is so high that it might cause a problem for the Ultrasonic.

EV3 (IR) Inferred - Used in the Compare - Proximity mode measures in centimeters. AT powers 20-75 the EV3 stops accurately. Since it measures light waves it would not be affected by loud sounds that will be apparent at the NYC FLL finals at the Javits Center tournament.

Note: Power levels above 75 does not allow a long enough response time for the Ultrasonics and IR Sensor to detect an object (however, you could try to push it to 80).

FLL - Trash Trek: The Color Sensor and the Field Mat...


     This year’s FLL Field Mat is of nice quality; teams need to be aware that the high gloss of the mat may cause faulty readings for the color sensors. Depending on the type of light source and angle of that light source, some lighting situations may cause bright reflections on black lines causing the color sensor to read the line as a color value less than black.

Students at Brics~2~Bots Academy ran a test on the FLL Trash Trek field mat, under normal house lighting, to see how an EV3 Color sensor would respond to the mat and this is what they observed…
  1. When line following with one color sensor and using Compare Reflected mode detecting the black line, lighting could be an issue where glare is being reflected off the mat depending on the angle of the lighting. You might get various readings at different parts of the same line. However, using Compare Reflected mode detecting the White bordering the Black line seems to work fine. For those who plan to use Compare Color mode it seems to work fine as long as the robot’s motor power is 30 or less and detects the line at an angle of about 20 degrees; more than that or greater power may cause it to miss or go off the line. For a smoother moving robot (less zig zag) use a power combination of 30 and 10.
  2. When using duel color sensors, the power of the True Value motor can be as high as 40-45, while
    the other motor has a power of 10-20. This allows the robot to move in a smooth straight line.
  3. This year’s mat is very colorful, so when detecting a white line or a black line you need to be aware of the part of the mat the robot has to move across to get to that White line or black line. 
Moving over a light colored area to detect a white line, in Compare Color Mode, the robot might stop or will hesitate over white (duh!) and light colors, but tends to move on to detect the pure white area. 

When detecting black in Compare Color Mode there seems to be no problem as long as the motor power was 50 or less; greater power can cause the robot to over shoot the line; it is moving too fast to have the sensor read and respond to the line.

Moving over dark colored areas to detect a white line, in Compare Color Mode, the robot might stop or hesitate.  When detecting black in Color Mode the robot might hesitate over dark colors and stop on black spots of .5 cm thickness. The thin black lines did not prove to be a problem with motor power of 50 or less. 

When detecting a white line, in Compare Color Mode, the sensor will read light colors mixed in and may hesitate or even stop. 

If you use the Compare Reflected Mode to detect white and moving over a multi-colored area, use GREATER THAN/EQUAL TO the threshold and a motor power of 50 or less. 

If you use the Compare Reflected Mode to detect black and moving over a multi-colored area, use LESS THAN/EQUAL TO the threshold and again a motor power of 50 or less.

It is recommended that teams run similar tests using different lighting situations before you start programing your missions. Note, we did not test the NXT Color sensor, but we suspect that the results would be similar.

FLL - Trash Trek: Scoring Apps


There are two FLL Trash Trek Robot Game Scoring apps for i-devices available:

FLL Trash Trek Scorer - Asha Seshan

FLL Trash Trek 2015 - Raymond Pang

Of the two, FLL Trash Trek Scorer - Asha Seshan is accurate. It has a Timer and Stopwatch. It starts with the 96 points that is given to the team in Black Bars and then adjusts the score as missions are accomplished or penalties are given. Scores can be saved.

The other scorer, FLL Trash Trek 2015 - Raymond Pang has a couple of errors, such as, scores for 5 animals when there are only 3. It looks as if the developer basically copied last years scorer; changing the words.

They are both free at the App store.

FLL - Trash Trek: Field Mat Revisited...


So this year, in addition to BASE, there is a SAFETY zone. 

BASE is where you will launch your robot (with its attachments and cargo), which MUST be COMPLETELY IN BASE. 

When your robot is returning to BASE the robot, its attachments, and cargo only needs to be COMPLETELY IN SAFETY,  before you may touch the robot; and as you know touching the robot or parts thereof is an Interrupt/Touch penalty. A penalty is worth minus 8 points, but the maximum for Interrupt/Touch penalties minus 32 points - that's nice.

However, there are other deductions:
     1. A Junk Penalty is for elements used and left PARTIALLY or COMPLETELY Out of SAFETY.
     2. Minus 8 will also be deducted for BLACK bars left on the mat or in SAFETY, that are not in their original state, not in the proper green bin, not in the black bin, or made into a flower pot with the compost.

Notice, the key word this year is "COMPLETELY." In previous years "IN" meant just crossing the line. This year the robot+ or models must be COMPLETELY IN! In a few cases the word PARTIALLY is used, read that rule carefully for the conditions. 

One last word about the BLACK bars...
     Technically, a team has 96 points at the start of the game for the 12 BLACK bars not in play yet.

1. So, 8 BLACK bars is in its original state, plus the ref 's 4 BLACK bars, that have not been used as a penalty yet = 12 Black bars
2. BLACK bars are worth plus 8 pts each = 16 pt, if you make a Flower pot with the compost.
3. They are worth plus 3 pts each, if they are in the proper Green Bin or Black Landfill Bin.

B2B - Academy: Our Duplo Pull Toy...



The creative talents @ Brics~2~Bots Academy have made a fun toy for toddlers. It's called the Buggy Pull Toy and it is made from Duplo(R) elements from LEGO(R) Early Simple Machines set and A Growing Caterpillar set. Not only is it fun to build and play with, but it shows toddlers (and some parents) what a gear is and how a linkage mechanism works - early STEM/STEAMThe linkage mechanism gives the illusion of the bug hopping and makes a slight clicking noise (kids love noise)



We submitted it to LEGO Ideas, so check it out and if you like it join and vote for it:

FLL - Trash Trek: The Field Mat...

FIRST LEGO League Trash Trek Field set-up is now on route to teams; so let's take a look at the mat…

First impressions, the mat is made of a good quality material and is very smooth. It is colorful with various shades of light and dark which “might“cause a problem for color sensors seeking for the black lines for line following; similar to the problems that were caused with the Food Factor and Nature’s Fury mats; but there are solutions to it. It will prove interesting how teams use their color sensors. Notice also, there are no color lines (red, green) as in Learning Unleashed, Senior Solutions, Climate Connections, No Limits, (Wow, I’ve been around that long? Even longer!)
And what’s this, a curved triangular shape for the Base area? How does it compared to the old square Base area? It is a slightly larger area and the curved outside will be helpful placing your robot in any direction you want to leave the base. Notice a second curved line. I wonder why? What do you think it is for?

B2B Academy: Animated Mosaics..

What is a mosaic?  Well, it is a design, picture, or pattern that is constructed by putting small colored bits of material onto a surface.  Architectural Mosaics can be made of colored glass, ceramic, or stone pieces, set in a type of mortar or cement. Mosaic art can also be made out of paper, bottle caps, popcorn; whatever.  The size of the pieces used determine the resolution (the fineness of detail that can be seen in an image); the smaller the pieces the greater the detail of the picture.

LEGO mosaics are made with plates of various sizes or bricks attached to a building plate. LEGO Animated Mosaics uses a MinuteBot® baseplate with bricks, plates with holes, beams, pins, and gears to create a design with moving parts. It could be manually operated or possibly be “motorized” with LEGO® Power Functions, if the movement is a continuous motion. It can also be “robotized” with LEGO® Mindstorms robotics.

Here is Olivia’s and Jonas’ Animated Mosaic project is of a Mimon MC and a Two Man Band in a concert.
