What is the name of Tesla’s humanoid robot launched in October 2022?

Correct — D, Optimus. Optimus, also called Tesla Bot, is the general-purpose humanoid robot Tesla, Inc. is developing. Elon Musk announced it at Tesla's first AI Day on 19 August 2021 with no hardware at all — only a person in a robot suit — showed a display model at the Cyber Rodeo event at Giga Texas on 7 April 2022, and unveiled semi-functional prototypes at the second AI Day on 30 September 2022. One prototype walked unaided across the stage; a sleeker version built around Tesla's own actuators was wheeled out and moved its arms. That event closed late on 30 September in the United States, and the world read about it on 1 October 2022 — the BBC's report is headed "Tesla boss Elon Musk presents humanoid robot Optimus" — which is why a question written in India can reasonably date the launch to October 2022. The contemporaneous reporting fixes the detail: the robot waved to the audience and raised its knees; a video showed it watering plants, carrying boxes and lifting metal bars; Musk said the robots would be mass-produced at a cost below USD 20,000 and be available in three to five years, spoke of "a future of abundance" and said Tesla was building in safeguards including a stop button that could not be tampered with, adding "we always want to be careful we don't go down the Terminator path". From the presentations, Optimus is designed to stand about 5 ft 8 in (173 cm), weigh around 125 lb (57 kg) and carry up to 45 lb (20 kg), and the pitch is that it runs the same AI system Tesla built for the driver-assistance software in its cars — a car that already perceives the world with cameras and neural networks is, on Tesla's argument, most of a robot already. Musk has said Optimus has the potential to be more significant over time than Tesla's vehicle business.

Why the other options are wrong — (a) The humanoid Indian newspapers have covered most, which is exactly why it is placed first. Sophia is a social robot built by the Hong Kong company Hanson Robotics, activated on 14 February 2016 and first shown publicly at SXSW in Austin the following month. It became famous for being granted Saudi Arabian citizenship in October 2017 — the first robot given legal personhood anywhere — and for being named the UNDP's first Innovation Champion in November 2017, the first non-human to hold a United Nations title. Structurally it is a conversational face and torso whose engineering budget went into expression and speech, not a walking general-purpose worker, and it has nothing to do with Tesla.  (b) Atlas is Boston Dynamics' bipedal humanoid, unveiled on 11 July 2013 with funding and oversight from the US Defense Advanced Research Projects Agency (DARPA) for search-and-rescue work; one of its hands came from Sandia National Laboratories and the other from iRobot. It is the robot in the parkour and backflip videos, and in April 2024 the hydraulic version was retired with an all-electric Atlas announced the next day. In 2022 it was a genuinely more capable machine than Optimus — which is precisely what makes it the strongest distractor here for a candidate who remembers a walking humanoid but not whose it was.  (c) Pepper is a semi-humanoid service robot from Aldebaran Robotics, later SoftBank Robotics, introduced in Tokyo on 5 June 2014 by SoftBank founder Masayoshi Son and marketed as the first personal robot that reads emotions. It has a wheeled base rather than legs, was deployed in SoftBank stores and other retail settings, and was manufactured until 2020. Two things rule it out at once: it is not bipedal, and it is not Tesla's — and its 2014 date puts it eight years before the event the stem describes.

Concept: "Humanoid robot" is a shape, not a capability, and the four names on this page cover three very different design goals. Social robots such as Sophia and Pepper put their engineering into the face and the conversation — expression actuators, speech, emotion recognition — because their job is interaction; Pepper does not even have legs. Locomotion and manipulation platforms such as Boston Dynamics' Atlas put it into balance and power density: a bipedal machine is unstable by construction and must recompute its footfall many times a second, which is why hydraulics dominated that class for a decade before electric actuators caught up. Tesla's Optimus is pitched at a third target, general-purpose labour, and its distinctive claim is not mechanical but computational — that the perception stack trained for autonomous driving transfers to a robot moving through a factory, so the hardest part is already paid for. Where the mechanical work does show is in the details: Optimus uses linear actuators built on planetary roller screws rather than ball screws, because a walking machine has to survive repeated shock loads, and the hand is where the generations are counted — 11 degrees of freedom on the Generation 2 hand shown in December 2023, 22 on Generation 3 in 2024. The bottlenecks in the field are the same everywhere: actuators with enough force per kilogram, batteries that last a shift, hands dextrous enough for unstructured objects, and onboard compute fast enough for real-time perception.
