Stanford's popular all-round housework robot is upgraded and releasedSecond generation version ALOHA2! This time, not only housework, but alsoWear contact lensesThey all dare to challenge. Still ableCarefully remove the wallet from the human pocket, took out a few banknotes from it, and put them back intact.



Opening a Coke and pouring a Coke smoothly are all trivial cases:


evenConvenience store milk without strawCan be opened easily and successfully:


Not to mention the simple operation of putting toys into three different bowls:


And you can also play the tossing game:


Netizens called excitng after seeing it!


According to the author, the cost of this set of equipment is $27,000.


Specific papers and online tutorials have been released so far.


What are the new upgrades?

ALOHA2 first improves the robot's gripper so that they can grip stronger and more stable.


The low-friction track design can output twice the original force to the top of the holder.


At the same time, the layout of the grip strap has been changed to improve the ability to grasp small objects.


It also replaces ALOHA's original scissor rail manipulator design and adopts a low-friction track design to reduce mechanical complexity and make remote control operations smoother.


Secondly, the gravity compensation of the forearm is improved. Using a constant-force tractor and a spring pulley system, the robotic arm can move and hover in more space and is stronger than the original rubber band.


Finally, the work cell around the frame has been simplified while retaining the necessary camera mounting points, which leaves more room for robot-robot collaboration.


At the same time, an ALOHAsim model was also released this time, which can use ALOHA to complete complex tasks in Mujoco without hardware equipment.


What is ALOHA?

ALOHA was originally launched by Stanford et al. as a low-cost open source hardware system for remote operation of dual manipulators.

In January this year, the Stanford team upgraded its robot control solution MobileALOHA. It was able to do various household chores and became a hit on the Internet at the time.


ALOHA supports two working modes: human remote control operation and fully automatic operation.

The recently released MobileALOHA is in a complex environment full of furniture. The robot system has learned various complex mobile manipulation tasks, such as calling an elevator, opening cabinet doors, wiping tables, etc., with only a small amount of human teaching.


During the learning process, manipulation information such as the speed of the moving base and the 14 degrees of freedom of the hands are used as input to the demonstration algorithm, and the system is jointly trained with ALOHA static data.

Moreover, the system is not only compatible with a variety of teaching and learning algorithms, but it is also very easy for users to master the teaching methods.

And if real people are used to operate it, more complex dishes can be made.


It is worth mentioning that after MobileALOHA became popular at that time, the collection of rollovers released by the author also attracted huge attention.

"Apparently robots are not ready to take over the world yet"


But now with the latest upgrade of ALOHA2, everyone has more expectations for robots doing housework~
