Military Robots in WW2

There is no doubt about it: Robots are destined for use on the battlefield. Researchers are trying to find the best mechatronic device to fight, investigate, cover rough terrain, survive explosions, and a myriad of other possibilities. Who is to stimulate this research?
For the development of military robots and drones, the government funds many public and private companies. Military ground robots must survive not only under fire but also in harsh environmental conditions. In this special webcast on mechatronics, Design News goes behind the scenes to explore how design engineers at several large and small robot design and fabrication companies tackle the design of these complex mechatronics systems, the design and development tools they use, and how they test their designs.
Broadly defined, military robots date back to World War II and the Cold War in the form of the German Goliath tracked mines and the Soviet teletanks




1. Goliath tracked mine (Nazi Germany)


The Goliath tracked mine was an unmanned German-engineered demolition vehicle. Employed by the Wehrmacht duringWorld War II, this caterpillar-tracked vehicle was approximately four feet long, two wide, and one tall. It carried 75–100 kg (165–220 lb) of high explosives and was intended to be used for multiple purposes, such as destroying tanks, disrupting dense infantry formations, and demolition of buildings and bridges.






Built in three versions; the first (Goliath E) powered by electic motors (2,500 built) was found to lack the power and range (particularly in cold weather) was subsequently replaced by an improved model (Goliath V) powered by a 702cc twin cylinder motorcycle engine. Finally a larger version was built to carry a 100kg explosive charge. In total around 4,500 of all versions were built seeing much service in both demolition and mine-clearing tasks.
Goliaths were used on all fronts where the Wehrmacht fought, beginning in spring 1942. They were used principally by specialized Panzer andcombat engineer units. 
Goliaths were used most notoriously in the Warsaw Uprising of 1944, as Wehrmacht and SS units were deployed to crush fierce Polish resistance by the Polish Home Army (Armia Krajowa). As the Poles had only a small number of antitank weapons, volunteers were often sent to cut off the command cables of the Goliath before it reached its intended target.[citation needed] A few Goliaths were also seen on the beaches of Normandy during D-Day, though most were rendered inoperative due to artillery blasts severing their command cables.
Although a total of 7,564 Goliaths were produced, the single-use weapon was not considered a success due to the high unit cost, low speed (only just above 6 mph, or 9.5 km/h), poor ground clearance (just 11.4 centimeters), vulnerable command cables and thin armour which failed to protect the remote bomb from any form of antitank weapons. However, the Goliath did help lay the foundation for post-WWII advances in remote-controlled vehicle technologies.



2. Teletanks (Soviet Union)


Teletank is a remotely controlled unmanned tank used in combat to minimize human casualties. It was a series of wireless remotely controlled unmanned robotic tanks produced in the Soviet Union in the 1930s and early 1940s. They saw some use in combat during early World War II, referred to as the Winter War in Russia. A teletank is controlled by radio from a control tank at a distance of 500–1,500 meters, the two constituting a telemechanical group


Teletanks were used by the Soviet Red Army in theWinter War and fielded at least two teletank battalions at the beginning of the Great Patriotic War. 


Teletanks were equipped with DT machine guns, flamethrowers, smoke canisters, and sometimes a special 200–700 kg time bomb in an armored box, dropped by the tank near the enemy's fortifications and used to destroy bunkers up to four levels below ground. Teletanks were also designed to be capable of using chemical weapons, although they were not used in combat. Each teletank, depending on model was able to recognize sixteen to twenty-four different commands sent via radio on two possible frequencies to avoid interference and jamming. Teletanks were built on the basis of T-18,T-26, T-38, BT-5 and BT-7 tanks.

Kong, kita kenapa ga jadi orang Jepang aja yah?

Ini cerita wa pas masih kelas 3SD, pas itu wa lg sering banget nonton film2 Jepang, baik film kartunnya juga film2 action sama perang nya. Yang wa liat di film2 buatan Jepang tentang perang dunia II itu, tentara Jepang itu keliatan baik, patriotik, rendah hati, penolong, dll yg baik2 semua dah ... trus kalo pemberontak China keliatan sbg pengacau, rampok, penjahat, dll, begitu juga tentara AS sama Uni Soviet, mereka ditunjukin sbg orang2 licik, sombong, rasis, kejam, dll.

Dulu juga wa itu ga gt bisa bedain Tionghoa sama Jepang biarpun wa sendiri Tionghoa, karena warna kulit, bahasa, trus budaya nya mirip banget jadi gw kira ya Jepang ini saudara kembar Tionghoa dalam segala hal.
Nah, pas itu gw ga tau kalo ternyata engkong wa ini anti-Jepang, karena dulu papa nya engkong gw, yg berarti  kongcoh (buyut) wa, dibunuh Jepang karena berani nentang permintaan Jepang yg pas itu minta sejumlah lahan, uang, dll.

Pernah suatu waktu wa bikin bendera angkatan laut kekaisaran Jepang (Imperial Japanese Navy) trus bilang gini ke engkong wa "Kong, kita kenapa ga jadi orang Jepang aja yah, orang Jepang kan hebat !"
Bendara Angkatan Laut Kekaisaran Jepang
Begini lah lengkapnya, di dialog ini, huruf E berarti engkong wa, huruf P berarti gw.


P: "Kong, kita kenapa ga jadi orang Jepang aja yah, orang Jepang kan hebat !"
E: "Heh !!", bilang apa kamu, hebat apa nya !!!?"
(engkong wa lgsung marah sampe ngebanting piring)
P: "Iya, orang Jepang kan hebat, bisa bikin film2 bagus, bisa bikin robot, bisa bikin kapal induk banyak banget  sama kapal battleship paling hebat sama paling hebat di dunia."

E: "Heh, kamu tau ga Jepang itu penjahat, pembunuh, dulu leluhur kamu itu dibunuh sama tentara Jepang !"
P: "Ah, tentara2 Jepang kan orang2 baik semua kong, trus yang mereka bunuh cuma penjahat, berarti leluhur kita yang penjahat makanya dibunuh."
E: "Apa kamu bilang?" "Coba bilang sekali lagi !"
P: "Leluhur kita itu penjahat makanya dibunuh sama tentara Jepang, tentara Jepang kan orang baik semua kong."

E: "Heh, kalo ngomong dipikir dulu , tentara Jepang itu jahat, waktu perang dunia II itu di Tiongkok, di Korea, di Malaya, di Nusantara, perempuan2 tionghoa itu diperkosa, dijadiin budak seks, dipermalukan, dibantai sama tentara Jepang! " "Kamu masih anak kecil ga tau kalo Jepang itu kejam."
P: "Emang kalo tentara Jepang perkosa perempuan tionghoa kenapa kong, bukannya itu buat hiburan?"
Kalo aku boleh ga perkosa perempuan2 tionghoa?"
(Engkong wa diem aja, trus geleng2 kepala, matanya sampe berkaca2 mau nangis, terus ngelus2 dada)
P: "Kong, aku kalo udah usia belasan tahun kepengen jadi Tentara Jepang kong, terus mau berbuat seperti Tentara Jepang, aku mau perkosa perempuan2 tionghoa juga."
(terus engkong wa langsung berdiri, trus langsung banting piring yg ada di meja makan, trus mau mukul wa, tapi ga jadi)
E: "Dasar anak durhaka pengkhianat bangsa dan leluhur!"  "I ga pernah nyangka bakal punya cucu pengkhianat bangsa dan leluhur  kaya you, udah fanatik Jepang, ga menghargai harga diri wanita tionghoa pula !" "Kalo I udah tau bakal jadi begini sih I gak kasih si I*** (nama panggilan nykp gw) nikah sama si A*** (nama panggilan bokap wa)."


Yah.... begitulah ceritanya, sebaiknya jangan dicoba dirumah, wkkwkw....


*Note: Waktu itu wa blom tau apa artinya perkosa yg asli, gw kira perkosa itu cuman cium2an trus ketawa2 an sperti yg di tampilin di film2 PD II versi Jepang itu.
