36-508: This concept was introduced to the legged locomotion community in January 1968 by Miomir Vukobratović and Davor Juričić at The Third All-Union Congress of Theoretical and Applied Mechanics in Moscow. The term "zero moment point" itself was coined in works that followed between 1970 and 1972, and was widely and successfully reproduced in works from robotics groups around the world. The zero moment point

72-509: A deal worth US$ 1.7   billion. The deal was subject to federal approval from the U.S. Federal Trade Commission (FTC) and other regulatory agencies. In September 2022, the FTC requested more data from both companies, amid concerns about Amazon's market power and the privacy implications of it gaining information about consumer floorplans. In June 2023, the UK's Competition and Markets Authority cleared

108-465: A docking station to which the robot returns to recharge at the end of its cleaning cycle. They work in conjunction with accessories that use both IR and RF . The company intentionally allows customers to hack the robot because they want people to experiment and improve the product. The API for the serial has been published and the serial port made easily accessible to make modifications easy to perform. In 2015, iRobot released an updated Roomba called

144-578: A full product release in 2006. Early models required either a special non-bleach cleaning solution or white vinegar to wash hard floors. Newer units could use plain water. Several versions were marketed. iRobot discontinued the Scooba line of products in favor of the Braava line of floor moppers in 2016. Dirt Dog was a variant of Roomba designed for workshop use that was released in 2006. The product picks up small objects such as nuts , bolts , dirt, and debris from

180-429: A predefined stability region. The position of the zero moment point is affected by the referred mass and inertia of the robot's torso, since its motion generally requires large angle torques to maintain a satisfactory dynamical postural stability. One approach to solve this problem consists of using small trunk motions to stabilize the posture of the robot. However, some new planning methods are being developed to define

216-648: A range of autonomous home vacuum cleaners ( Roomba ), floor moppers ( Braava ), and other autonomous cleaning devices.

This product, which was meant to look like a human infant, employed animatronic facial expressions and

396-407: Is an important concept in the motion planning for biped robots. Since they have only two points of contact with the floor and they are supposed to walk , " run " or " jump " (in the motion context), their motion has to be planned concerning the dynamical stability of their whole body. This is not an easy task, especially because the upper body of the robot (torso) has larger mass and inertia than

When training data for the Roomba J7 vacuum robot ended up on Facebook, like

720-640: The acquisition, saying it wouldn't lead to competition concerns in the country. The European Commission launched a formal investigation into the proposed purchase in July 2023, citing that it would "allow Amazon to restrict competition in the market for robot vacuum cleaners ('RVCs') and to strengthen its position as online marketplace provider." In July 2023, Amazon reduced the offer price to $ 1.42   billion after iRobot raised $ 200   million in new debt to fund its daily operations. In January 2024, Amazon and iRobot announced they would end their plans to merge in
