Service Robots for Education, Therapy, & Entertainment


In recent years, high-tech surgical rooms have been getting insightful medical robots, advanced educational institutions have been replacing human teachers with all-knowing AI-based systems, and conceptual restaurants have adopted robots as servers instead of humans. The list of such innovative integrations may go on and on. But we can say for certain - robots are gradually becoming a part of our daily lives.

Mainly, countries with highly developed economies are focusing on smart and robotized systems being quite complex and expensive to implement. But let’s get a bit deeper into the topic and briefly review some of the most iconic examples of service robots.

Social Robotics

Did you know that in South Korea and Alaska, robots are already replacing teachers in some schools? And although currently, most robotized teachers work under human supervision, in a few years, as technology develops, they will certainly acquire much more “teaching freedom”.
For instance, one of the most famous developments in this niche - a social robot named Nao - is able to fulfill a math teacher position. It was first tested in mass education practice back in 2012, in one of Birmingham's elementary schools.

Nao is currently teaching at a Harlem school, helping students develop math skills. The major abilities include the recognition of multiple languages and speech reproduction. However, Nao cannot solve math problems. Instead, it only gives tips that help students find the right solution. It also helps children suffering from autism develop social skills.

Robots for Home Use

As for personal home robots, they are mainly used to help with cleaning, cooking, and caring for children and the elderly. Among home service robots, the one that stands out is a programmable 3D printer that bakes pancakes, which you can purchase on Amazon. Some of the most helpful robots at home are robotized vacuum cleaners, which have become quite popular in recent years.

There is also a more advanced variation of an intelligent vacuum cleaner - a personal home robot Valerie that can wash dishes, discuss various topics with the house owner, and even call rescue services. Valerie is a human-like android, which still may give many users out there creeps.

Then, there are pool cleaning robots that move along the walls and bottom of the pool. Via special brushes, dirty water is thrown into the filter compartment and after the procedure, you just have to wash the filter.

You can also make your domestic routine more comfortable by purchasing an automated table, for example, an angular model. Learn more about such handy tables.

Robotics in Personal Care

Many types of robots for personal use are efficiently used to help people with disabilities. So, in 2017, Toyota conducted the first tests of its Human Support Robot assistant for disabled people at home. The robot was equipped with a manipulator, which was supposed to carry objects of various shapes. The developers also installed cameras on it that allowed for independent navigation in space.

This personal robot has been tested globally in hospitals throughout 2017, after which, the Toyota team of engineers faced a more difficult task: to adapt it for more difficult conditions so that the robot would efficiently operate at home and help disabled people in their everyday lives.

The previous version of the robot was controlled manually via a tablet, but now, the tablet can be fixated to a wheelchair so that the immobilized user could use the stylus to control the assistant. You can learn more about personal robots on our blog and even purchase components for creating one yourself in our store.

Entertainment Robotics

Perhaps the most iconic area of entertainment in which robots have found their application in the restaurant business. At one time, in many Asian countries, restaurants where instead of real waiters, people were served by entertainment robots have blown up. However, in practice, this was not such a good idea, and many restaurant business owners had to return to traditional forms of service.

The problem was that robots used for entertainment were not able to carry soup or other food that required stability (probably, they just didn’t have high-precision linear drives on hand, which would definitely help). Pouring drinks for guests at the table is another near-to impossible task for a mass-production entertainment robot to handle.

Lastly, entrepreneurs were far from being satisfied with the “price of the matter”, because, in order to “hire” a service robot, you had to pay about 8 thousand dollars, and then spend several hundred more every month on maintenance. That’s why to this day, robots in the restaurant business mainly serve as a kind of attraction for curious visitors.

Examples of Robots

Now you know a bit more about some prominent robots in the fields of education, entertainment, domestic life, and care for immobilized people. But we also would like to briefly talk about a more complex development - a robot arm that is able to independently carry out the most complicated surgical operations.

This renowned robot example is named after the famous historical character - Da Vinci. It consists of two blocks - the first is intended for surgical manipulations, and the second, presented in the form of robot-arms, has advanced actuators at its core.

One of the robot arms captures everything that happens on the operation site with the camera, the other two reproduce the movements of the surgeon operator in real-time (the specialized joysticks and a 3D-zoom screen are used to guide the process) and the fourth “hand” assists.

Today, this robot is used in several hundred clinics around the world. You can try to create a robotic arm with your own hands using linear drives which you can profitably buy in our store. Also, learn more about the specifics of hand robots.

Summary

If we talk about kinds of algorithms social robots are based on, anything you can imagine can be implemented. As for the mechanisms for implementing their movement, things are much simpler - as a rule, linear actuators are responsible for setting things in motion.
