Indonesia is ancient human hominid residing in Indonesia.
There are six types of early humans in Indonesia, namely:

    Meganthropus paleojavanicus
    Pithecanthropus Erectus
    Pithecanthropus Robustus
    Pithecanthropus Mojokensis
    Homo soloensis
    Homo Wajakensis
Characteristics

    Meganthropus paleojavanicus
        It has a thick cheekbones
        Having a strong chewing muscles
        It has a prominent brow ridge
        Has a bulge behind the sharp
        It has no chin
        Has a well-built physique
        Eating plant species
    Pithecanthropus

        Pithecantropus Erectus
        Meaning: the human ape walking upright. Discovered by Eugene Dubois in Sandpipers in 1891. The fossils were discovered in the form of the upper jaw bone skull, jaw and leg bones. This fossil was found in the middle Pleistocene.

        Height of about 165-180 cm
        Brain volume ranged from 750 - 1350 cc
        Body & strapping limbs, but not setegap Meganthropus
        Equipment and tools chewers powerful neck
        Graham great shape with very strong jaws
        Forms a thick brow ridge across the forehead from side to side
        Thick nose shape
        The back of the head seemed to stand like a lady berkonde
        Face thrust forward, backward sloping forehead
    Homo
Homo soloensis
Soloensis Homo fossils found in Ngandong, Blora, at Sangiran and Tigers Connect, Sragen, by Ter Haar, Oppenoorth, and Von Koenigswald in 1931-1933 from Upper Pleistocene layers. Soloensis Homo, which lived about 900,000 to 300,000 years ago. Brain volume reached 1300 cc.
According to Von Koenigswald this being higher level than Pithecanthropus Erectus. Estimated that this creature is an evolution and Pithecanthropus Mojokertensis. By some experts, classified as Homo Homo neanderthalensis soloensis which is a type of hominid Homo Sapiens from Asia, Europe, and Africa come from the Upper Pleistocene.

    Brain volume between 1000 - 1200 cc
    Height between 130-210 cm
    Neck muscle shrinkage
    Not face thrust forward
    Stand up straight and walk more perfect

How to make a line follower robot

  Making Follower Robot Line Analog (free)

 willing to share on how to make a robot line follower analog, analog No matter what he meant and what is the difference with digital .... analog line follower robot does not need any software robot programming (software) while the line follower micro (digital) involves software ... it sich cuman one basic difference, for difference whores ... what was it ... anyway it Dech, hehe ...for you who just got interested in the world really want to make a robot and the robot is first learned from the base, making nach analog line follower robot is the basics of designing a robot ... (q first learning of analog ...) course will develop to digital ...what are the basic components of the system sich robot that ....? My Setau robot consists of component inputs (insert, eg sensors), processing, and output (output), nach analog line follower robot system is not complex if dibandikan with humanoid robots such as ASIMO example, ... to make the robot base we do not need to make a robot Asimo , hehe .... really hard time, too dah analog line follower robot can be said, because if the object is said to have the robot can stir atw run itself automatically without operator assistance.the basic components of the robot system:
 hmmm wrote what else ya .... q immediately wrote dech nich share any set of analog line follower robot ....
 Analog Line Follower circuit above there are 3 main parts, namely the sensor, comparator and driver. For the sensor used photodioda as a light sensor, while komparatornya using IC LM 324 as a voltage comparator and for drivers to use H-Bridge transistors.The workings of circuits Analog Line Follower is as follows:A. Sensor Working PrincipleThe sensor used consists of photo diodes. This sensor resistance value will be reduced when exposed to light and work on riverse bias conditions. To use the light sensor LED Superbright, this component has a very bright light, so it is enough to supply light to the photo diode.
 Image sensor circuitHow it works:
 Image sensor is not exposed to lightIf the photo diode is not exposed to light, the resistance value will be large or can we assume infinite. So that the current flowing in the comparator is very small or can be assumed to logic 0.
 Image sensor is exposed to lightIf the photo diode is exposed to light, the photo diode will be a source of voltage and resistance value will be small, so there will be no current flowing to the comparator and logic 1.B. Working Principle ComparatorThe comparator in this rangaian using IC LM 324 which contains a series of Op Amp is used to compare the input from the sensors. Where the input will be compared from the Op Amp IC LM 324 the high pulsed output. So it is not necessary to pull up the output. This IC can work pad range 3 volts to 30 volts and can work with the normal starting voltage of 6 volts.In this series there are 4 LEDs, which serves as an indicator. To set tagangan in comparison, connect Variable Resistor (VR) between the two OP Amp IC LM 324. For LM324 datasheet please download here.
 Picture comparator circuit► If no current flows from the sensor circuit to circuit the input voltage for this circuit is 0 volts, resulting in IC voltage at terminal 1 (+)> (-), then the LED-A on, while on the opposite IC 2 LED -B off.► If there is a current flowing from the sensor circuit to circuit the input voltage to the circuit is close to Vcc, resulting in IC voltage at terminals 2 (+) <(-), then the LED-B on, whereas the IC 1 otherwise the LED- A off.Conditions between points A and B will always invertibility.C. Working Principle Motor DriverDriver is a circuit made up of transistors that are used to drive a DC motor. Where the main components are installed according to the transistor characteristics.
 Figure H-Bridge driver circuit TransistorAt the time of input A logic 1, then there is current flowing in the circuit, resulting transistors 1 and 4 on the basis of bias because, so the motor rotates. So when the input A logic 1 then the input B will be a logic 0, so the transistor 2 and 3 will be off.At the B input logic 1, then there is current flowing in the circuit, resulting transistors 2 and 3 on the basis of bias because, so the motor spins but in the opposite direction.Reference: Electronic Engineering Polytechnic Institute of Surabaya, Training Line Tracer, ITS, 2006.for a fuller explanation of the circuit, you can memdownload analog line follower robot paper here ... Good luck ...ni nach analog him my robots photo gallery .... (old school ... but this tenan beginning of everything .....)

Authorities asked residents to stay at home during a snowstorm.
Five states along the east coast, Massachusetts, Rhode Island, Connecticut, New York, and Maine declared emergencies. Millions of residents in the five states it is recommended to remain in the house.
Fuel shortages have been reported ranging from Connecticut to New York City after city car owners lined up to buy oil at public refueling station to fill the tank of a vehicle, generator and snow blower.
Nearly all flights in areas affected by the snow storm canceled and train services are also suspended.
Meanwhile, cities in eastern Canada, Ontario, New Brunswick, Nova Scotia and Newfoundland was also hit by a snowstorm.
Local media reported there were 200 traffic accidents in Ontario so far. At least three people were killed.
