d. Cheetah

ANSWER: Cheetah
 
Now, a robotic cheetah!Scientists have developed a lightweight robotic cheetah. It efficiently uses its energy to replicate the movements of the fastest land animal in the world.

The scaled-down robotic version moves using only about 15 per cent more energy than a real cheetah.

While walking robots tend to be large and heavy, taking cumbersome steps that use a lot of energy, the cheetah runs swiftly and smoothly.

The research provides valuable knowledge that can be used to optimise the robots of the future, designed to support us in areas such as healthcare or housekeeping.

The knowledge gained from the project can also be put to good use in rehabilitation robots or advanced prosthetics that are equipped with robotics.

The backbone proves crucial to the power this big cat generates. Bending and extending its spine enables the cheetah to move efficiently, run exceptionally fast and make huge leaps.

The main difference between existing walking robots and the cheetah robot is therefore the backbone.

Cheetahs are also able to store a lot of energy in their muscles for later use. This too is something one would have imitated by fitting carefully selected springs in our robot's legs.

The prototype weighs in at 2.5 kg and is 30 cm long–twenty times lighter than a real cheetah and four times smaller.

Taking into account the weight difference, the robot moves using only about fifteen per cent more energy than a real cheetah.

The robot can currently reach a speed of about one kilometre per hour.
