A robotic dog that can dance, flip and jump is made by a team of students – and they encourage people to build their own dog.
The robo dog detects when it is out of position and uses & # 39; virtual springs & # 39; to jump upright.
It was created for the purpose of being reproduced by everyone and the team has published their designs and blueprints online to encourage people to make their own robots.

The makers of Doggo wanted to share their joy so much that they made the plans, code and a delivery list available for free on GitHub, a specialized platform for developers to share computer code.
On the Stanford Doggo project Github blog, the students describe themselves as students and graduates in the Stanford Student Robotics club and part of the & # 39; Extreme Mobility team & # 39; from the club.
The students wrote: & # 39; We have been working on legged robots for the past year and a half.
& # 39; Our newest robot, Stanford Doggo, is a four-legged robot with a shoe box that can walk, trot, show off and jump around. & # 39;
Nathan Kau, a 20-year-old machine builder and leader of Extreme Mobility, said: “We had seen these other four-legged robots under investigation, but they were not something you could bring into your own lab and use for your own projects.
& # 39; We wanted Stanford Doggo to be this open source robot that you could build yourself with a relatively small budget. & # 39;
Club members estimate the cost of Stanford Doggo at less than $ 3,000 (£ 2,364), a figure they say includes manufacturing and shipping and that and almost all components can be purchased directly online.
The four-legged robot is designed to navigate through different terrains using motors that detect external forces and determine how much force and torque each leg must respond to.

HOW DOES & # 39; DOGGO & # 39; WORK
A team of Stanford students has created a robot dog that can dance, flip and jump.
It is a four-legged shoe in shoe box format designed to navigate through different terrains.
The motors detect external forces and determine how much force and torque each leg must respond to.
With a speed of 8,000 times per second, it is the power source behind the & # 39; spring & # 39; of the robot.
Doggo can jump off the ground three and a half feet (1.1 m) at the moment.
The robot costs less than $ 3,000 (£ 2,364), including production and shipping costs.
Almost all components can be purchased directly online, the makers say.
The plans, code and a supply list to recreate your own robo dog are available for free on GitHub.
By pushing the limits of the robot's software, Stanford Doggo expanded its jumping range and can now initially jump three and a half feet (1.1 m) off the ground, from two feet (0.61 m).
The smart motor is also the power behind the characteristic dance of the robot, says its creator.
The engine recreates at a speed of 8,000 times per second and is the essential powerhouse for the jumpy boogie that can be run without springs.
Instead, the engines act as a system of virtual resources that send the robot back in the right form when they feel it is out of position.
& # 39; At that time we realized that the robot performed better in some respects than other four-legged robots used in research, even though it was very cheap, & # 39; Mr. Kau added.
To make Stanford Doggo replicable for everyone, the students completely rebuilt it.
This meant spending a lot of time researching easily accessible supplies and testing each component as they made it, without relying on simulations.
The students wrote on their blog: & # 39; Many of the custom pieces are 3D printed or waterjet, which means that you only have to do post-processing work.
& # 39; The primary links on each leg assembly (which are water jets) require that you drill a hole for a set screw and then tap it. & # 39;
Natalie Ferrante, 19, a mechanical engineering student and member of Extreme Mobility, said: & It is about two years since we first had the idea to make a four-legged friend.
Many of the custom pieces that have gone into the robot use advanced technology such as 3D printing or water jet cutting. The image shows how Doggo does a backfiip
& # 39; We certainly made several prototypes before we actually started working on this iteration of the dog & he said.
The Extreme Mobility also works with Robotic Exploration Lab from Zachary Manchester, assistant professor of aerospace engineering at Stanford, to test new control systems on a second Stanford Doggo.
It is hoped that such a robot would one day have wider applications and would even be used to replace people in dangerous scenarios.
Patrick Slade, a graduate student of aviation and space travel, said: & We hope to be able to offer a basic system that everyone can build.
& # 39; Suppose, for example, you wanted to work on search and rescue; you could equip it with sensors and write code on top of ours that would make the rock climb or dig out through caves.
& # 39; Or maybe grabbing stuff with an arm or a package. & # 39;
MIT has also developed a robot the size of a small dog that can perform back-flips with the agility of a champion gymnast. The four-legged machine (photo) that the & # 39; mini cheetah & # 39; is virtually indestructible, according to the makers
to this end, the team has already finished building a robot that is twice the size of Stanford Doggo and can carry around 13 lbs (6 kg) of equipment and has been named Stanford Woofer.
Recently MIT also has one a small dog sized robot can perform back flips with the agility of a champion gymnast.
The four-legged machine, the & # 39; mini cheetah & # 39; is, according to the makers, virtually indestructible.
It ties in with a number of similar projects that seek to create nature-inspired technology for human use, known as biomimetics, that also contains potential for military use in the future.
The MIT robot runs twice the speed of an average person and can easily run over bumpy, uneven terrain.
It has flexible metal limbs that provide stability and the robot can quickly raise itself with a swing of its & # 39; elbows & # 39; if he ever falls over.
WHAT IS BIOMIMETICS?
Biomimetics is the process by which ideas from nature are adopted and used in technical design.
It uses nature's facial expressions and wildlife adaptations to different environments and conditions to create solutions to human problems.
It is an interdisciplinary field in which principles of engineering, chemistry and biology are applied to the synthesis of materials, synthetic systems or machines that have functions that mimic biological processes.
Biomaterials are all natural or synthetic materials that interact with every part of a biological system. Biomimetic designs could be used in regenerative medicine, tissue manipulation and drug delivery.
