This specific weapon unlike the others does not seem to exist outside of Samurai Jack. I've done a lot of research around many types of weapon that could be related (rope,wire,string,exploding) to name a few.
The only real mention to wire weapons anywhere is the Garrote and it's many other names.
The wire weapon looks to be similar to a line of explosive gun powder so I went down the route of explosive weapons.
I then found this the Bangalore Torpedo, now this is actually a charge placed in several connected tubes which is then used to remove obstacles at a distance and keep the detonator out of harms way. The way it lies on the ground and it's appearance are the most similar things I've found to the wire weapon used by the ultra bot.
As for exploding rope weapons, I found Bolas whilst not inherently similar they could have aided in inspiration for an exploding rope/wire weapon.
