It's the 4th and the last challenges from Lego which is the humanoid type;Alpha Rex.
Well,maybe it's the coolest sample from Lego (and the most boast of from Lego). its also disappointing me with a lot of flaw part.Not to mention that Alpha Rex just dragging it legs to walk.Well,as I said before,it just samples and we must learn to accept it.If you've dissatisfaction with it,use your creativity and go make it yourself.That's what the Lego want actually.
To make a complete Alpha Rex,it require 4 parts to build it (Legs,Arms,Head and Sensors).But don't worry.Once you finished the legs and arms,it'll be no sweat to make the head and sensors.
The first problem I had is,the hand not move smoothly.To encounter that make sure you make the A motor power is 60%.Don't make the motor power to high or you'll break the gear or the worst : motor.
Got problem how to connect the A move blog to the sequence beam(a white stick with a hole)?
I got stuck with it for hours and maybe its so easy as the Lego doesn't write it in the instruction
To Lego-I'm not smart enough to figure it out myself
Just press the SHIFT button and while hold it,click the left mouse and drag it to connect the sequence beam.
Before running the program,make sure you make the right hand(with color sensor equipped) pointed forward.The best one is to make the bar (stick or whatever) that attached to the left hand pointing to you (270").Turn the black gear on the right side of its back to change it.
Maybe you noticed Alfa Rex is steering a little to the left while walking before asking the green ball.
This caused by the C move block to make the Alpha Rex walk.
Note:The C motor move first to different the C motor (left foot) and B motor (right motor) position.It'll make the walking motion when the "CB move block" in action
But don't be annoy with it.It'll steer to the right back after you give the right ball.With this,it'll look like walking on the straight line.
Ok,here how it should work,according to the test guide instruction:
1:Before running the program,the Alpha Rex's hands should be closed and pointed forward.Put your hand in front of the Alpha Rex and it should start walking.
Ok,could you make the Alpha Rex's hands closed and pointed forward?I couldn't make it and wasting time finding the mistake.Then,I realize something from the video.
See?The right hand obviously open when pointing forward.
Ok.ok..next.Alpha Rex should be walking when appointing your hand in front of it.Then,stop,and ask the green ball.If you give the right ball it;ll start "dance".
Actually instead of dancing,it'll walking forward.Look the program back.It'll never dance.
Well,enjoy my Alpha Rex fashion show
Despite it flaws,love Alpha Rex and before I "kill" him to make another projects,I'll teach him a "real dance" .Don't worry,Alpha Rex
