Multifunctional Robot PR2

Staff at Willow Garage have created a customizable robot called Personal Robot 2 that can perform up to 7 different functions. In its appearance, the robot resembles a human. It has a base, torso, arms and legs. The PR2 can move, operate objects manually, and several sensors and sensors help sense and evaluate the surrounding environment. Because the android software comes with source code, it can be taught to do many things.

The robot finds the best sockets in any room and loads itself. He is also capable of transferring liquid from one glass to another, turning the pages of a book, picking up a pen or plate. The PR2 performs even more human-like operations, but also performs more complex operations.

1. Assemble the Rubik’s Cube

The robot picks up the task very quickly. At first, he carefully scans all the walls of the cube, picks up the cube in his “head” and then starts working. Of course PR2 was not designed to solve puzzles. This is just one of the research tools that make robotic testing possible.

2. Cook a meal

Which housewife would refuse such an assistant? He knows how to shake butter with sugar, break eggshell and bake cookies. Unfortunately, it’s not neat and leaves a mess in the kitchen.

Together with another robot, Rosie PR2 can bake a delicious cake. All he needs is access to the Internet and refrigerator products.

After receiving the task, the robot finds the required recipe and explains the whole cooking process. By scanning the barcodes, the machine selects the right products and starts the production by performing the usual operations of opening / closing the packaging, picking up the ingredients, cutting them, and so on. The price of the PR2 is quite high – 400 thousand dollars. So it is better to run the kitchen yourself and it will be cheaper and of course tastier!

3. Laundry and folding clothes

Many robots handle their various solid objects perfectly. And what about soft ones like a towel? What steps does the robot have to do? Can he handle a large pile of laundry?

Pieter Abbeel, a professor in the Department of Electrical Engineering and Computer Science at Berkeley University, and his students have created a robot that knows how to wash and flex clothes. In order for the robot to do its job correctly, programmers had to create thousands of lines of code. First of all, by holding the garment in its hands, the robot becomes acquainted with its geometry. And two wide-angle cameras – his “eyes” – allow the robot to create a 3D object model. One by one, the processor rejects all hypotheses until he finds the correct “I hold the shirt in the manipulator collar.” Then the “shirt” folding algorithm comes on. Although the robot’s movements are sudden, even slightly daunting, it folds nicely.

4. Read aloud

Employees of the University of Pennsylvania’s GRASP Lab have trained PR2 to recognize words. It can read any note aloud, from simple notes to long alerts on tables.
The robot learns to read just like children. For now, he can read short phrases. But as technology advances, robots will certainly be able to read, for example, tales for children or long stories.

5. Sort products

Stanford University researchers have developed a PR2 program that allows a robot to pick up objects, scan them by barcode, and even place them in shopping bags.

The robot recognizes objects according to the same principle as clothes. First he gets to know the object, explores its shape, and creates a three-dimensional projection. After doing this analysis, the robot decides how to pick things up better with its mechanical hands.

The robot also knows how to measure the size of an object and recognize it by scanning a barcode. So, PR2 can work as a cashier at the mall or as an assistant to a wealthy host while shopping in stores.

6. Sort opaque objects

Jivko Sinapov, a researcher at the University of Iowa’s Robotics Laboratory, will be able to sort opaque objects and determine what’s inside without opening them. He picks up the bottle, takes it from one hand to the other, turns and determines whether there is liquid or solid inside.

7. Play billiards

After all the difficult work, the robot must rest. The creators of Willow Garage taught their work to play billiards.

Built into the PR2’s head, the Polaroid camera helps you locate a ball on the pool table, using the trackpad to control the billiards. And thanks to the software, the robot can choose the most appropriate stroke option by hitting the ball.

It’s no secret that this robot is capable of so much! I think many would like to have one at home or at work. Imagine if this robot were to do all the work for you or fix the faulty stuff? One plug-in and this machine can make your life easier instantly. There is a case where this robot is turned into a workman and uses cordless rotary tools to perform simple tasks such as engraving or grinding. We hope that this robot will continue to be nurtured and refined, thus improving and performing many different life functions.
