Giant scorpion robot that can stab victims with its tail
5 March 2016, Nirapad News: It is one of the most terrifying robots ever made.
Students have developed a 3D-printed scorpion to demonstrate the ‘intuitive and complex mechatronic functions’ of the technology – and it can even stab people with its tail.
The Scorpion Hexapod is designed with six-legs that moves in all directions, responds to interactions and has a tail that leaves a ‘mark’ when it attacks.
The students from Ghent University in Belgium created the robotic scorpion as part of the ‘Mechatronics Design and Embedded Prototyping’ course, with the goal of re-designing the Stigmergic Ant Hexapod Robot – a previous student’s creation, reports 3ders.
‘Our goal was to design an impressive, digitally designed robot with lots of possibilities towards interaction and functionality,’ said Robbe Terryn, one of the three creators of the Scorpion Hexapod.
‘The scorpion seemed the appropriate animal as an inspiration for this robot, because the tail and claws could be given all kinds of functions.’
‘Another goal was to improve its design using multiple digital production techniques.’
‘Unlike the original ant, which used only laser cutting, the scorpion robot consists of a body, six legs, two claws and a tail, all of which were produced suing 3D printing, laser cutting, and CNC milling.’
A majority of the electronic parts from the ant-bot were re-used for the scorpion, except an Arduino Nano replaced the Mega board and a more power battery pack was implemented.
The modules for the legs and tail were 3D-printed, the two sheet ABS body was laser cut, and the shell, claws, leg ends and tail stinger were made from thermoformed polystyrene, reports Gizmag.
‘These foam models were afterwards used as a mold to thermoform a polystyrene copy of these parts,’ explained Terryn.
‘The body frame exists of two 6mm plates, including all holes for cable management, etched codes, snap fits, etc.’
And a red marker pen was added instead of the tail to leave a stamp on the scorpion’s prey.
The system was designed with different moves and a few auto responses to interaction, although it can be controlled through a computer.
It can walk in all directions, step over elevated surfaces and perform movements a real scorpion would such as, move its claws and strikes its tail.
It uses a long range IR sensor and three short range ones positions in the upper shell so it can detect user proximity and there is also a front-facing camera.
Because the team used advanced digital production technique, the scorpion is lighter and more durable than the ant-bot – and it has more ‘advanced autonomous functions’.
