Researchers at the University of Washington recently developed a new protocol for training robots and
Working with the Rubik's Cube requires sufficientaccuracy, especially for long manipulation sequences. Therefore, the ability of the robot to correctly and quickly manipulate the puzzle is indicative of high performance. Our protocol requires the robot to complete a sequence of Rubik's Cube manipulations as quickly as possible.

The new protocol evaluates both the speed and accuracy of the robot when solving a Rubik's cube. As part of the study, scientists demonstrated its potential and applicability in a series of tests.
In the first they used it to evaluate twobasic algorithmic methods for improving the manipulative skills of a machine using the PR2 platform. Then the scientists gave another well-known robot named Herb to solve the Rubik's cube. This confirmed that their protocol can be applied to various platforms.
“Robots can get high scores on ourprotocol, successfully performing a large number of manipulations and / or minimizing the time required to perform manipulations, the scientists conclude. “So our protocol establishes a baseline against which other researchers can compare their systems.”
Due to a series of sequential movements, robotsIt's difficult to manipulate a Rubik's cube. This means that individual errors a machine makes can accumulate, affecting its overall performance on a task.
It is the accumulation of errors that is the keya problem affecting the performance of robots in sequential manipulation tasks. Since the Rubik's Cube involves sequential manipulations, they suggest using a puzzle to evaluate the manipulative skills of robots and compare them with those of other robotic systems.
