This toy combines puppetry, mobility, and utter terror

ADAM Savage of Mythbusters fame discovered something that is both awesome and entirely likely to freak you out.

Hong Kong technology manufacturer Robugtix developed and, briefly, sold a remote-controlled spider with such powerful processing and realistic articulation that it's hard not to get the creeps just watching videos of it.

As Adam explains in the video, the Robugtix T8 is controlled by a sophisticated motherboard that controls the spider's abdomen and eight legs. 

Each leg is motivated by three separate servos, giving the T8 an extremely realistic level of motion all thanks to a state-of-the-art algorithm in the gizmo's processor. 

Besides the servos and motherboard, every part of the body is made from 3D printed material.

This means it's seriously light - weighing around 300 grams.

More importantly than the spider itself is the algorithm powering the movement engine. 

"The Bigfoot Inverse Kinematics Engine handles all the complex math calculations necessary for controlling multi-legged walking robots," says the Robugtix website.

"All computations are safely hidden from the user in the form of a black box.

"This means that the user only has to send short and simple commands to the robot (for example, instructing it to walk forward at a desired speed) and the engine will automatically take care of all the details, including inverse kinematics, leg trajectory planning, leg gait coordination, motor control, etc.

"This makes it quite easy even for absolute beginners to play with advanced robotics."
