A Segway is a two-wheeled, self-balancing personal transporter device invented by Dean Kamen. It is a registered trademark of Segway Inc. It was brought to market in 2001 as the Segway HT, and then subsequently as the Segway PT.HT is an initialism for "human transporter" and PT for "personal transporter."

Contents

Ninebot, a Beijing-based transportation robotics startup rival, acquired Segway Inc. in April 2015, broadening the company to include other transportation devices. In June 2020, it was announced that it would no longer make the Segway PT. [1] [2]

History

Independent company

The Segway PT, referred to during development and initial marketing as the Segway HT, was developed from the self-balancing iBOT wheelchair which was initially developed at University of Plymouth, in conjunction with BAE Systems and Sumitomo Precision Products. [3] The first patent of human transporter was filed in 1994 and granted in 1997, [4] followed by others, [5] including one submitted in June 1999 and granted in October 2001. [6]

Prior to its introduction, a news report [7] about a proposal for a book about the invention, development, and financing of the Segway PT [8] led to speculation about the device and its importance. John Doerr speculated that it would be more important than the Internet. [9] South Park devoted an episode to making fun of the hype before the product was released. Steve Jobs was quoted as saying that it was "as big a deal as the PC", [9] (he later expressed a negative opinion, saying that it "sucked", presumably referring to "the design" – but also referred to the (presumably high) price point, asking, "You're sure your market is upscale consumers for transportation?") [10] The device was unveiled on 3 December 2001, following months of public speculation, [11] in Bryant Park, New York City, on the ABC News morning program Good Morning America , [12] [13] with the first units delivered to customers in early 2002. [14]

The original Segway PT models featured three speed settings: 6 miles per hour (9.7 km/h), 8 miles per hour (13 km/h) with faster turning, and 10 miles per hour (16 km/h). [15] Steering of early versions was controlled using a twist grip that varied the speeds of the two motors. The range of the p-Series was 6–10 miles (9.7–16.1 km) on a fully charged nickel metal hydride (NiMH) battery with a recharge time of 4–6 hours. In September 2003, the Segway PT was recalled, because if users ignored repeated low-battery warnings on the PTs, it could ultimately lead them to fall. [16]

In August 2006, Segway Inc. discontinued all previous models and introduced the i2 and x2 products, which were steered by leaning the handlebars to the right or left, [17] had a maximum speed of 12.5 mph (20.1 km/h) from a pair of two-horsepower (1.5 kW) Brushless DC electric motors with regenerative braking and a range of up to 15–25 mi (24–40 km), depending on terrain, riding style and state of the batteries. [18] Recharging took 8–10 hours. The i2 and x2 also introduced the wireless InfoKey which could show mileage and a trip odometer, and put the vehicle into security mode, which locked the wheels and set off an alarm if it was moved, and could also be used to turn on the PT from up to 15 feet (4.6 m) away. [15]

Segway Inc. was acquired by British businessman Jimi Heselden from its U.S. inventor Dean Kamen in December 2009. A year later, Heselden died after he "plunged into the River Wharfe while riding a rugged country version" of Segway PT. [19] [20]

Versions of the product prior to 2011 included (in order of release): [21]

In March 2014, Segway Inc. announced third generation designs, including the i2 SE and x2 SE sport, new LeanSteer frame and powerbase designs, with integrated lighting. [23]

Subsidiary of Ninebot

Ninebot, a Beijing-based transportation robotics startup and a rival of Segway Inc., acquired Segway Inc. in April 2015, having raised $80M from Xiaomi and Sequoia Capital. [24] [25] The acquisition came months after the U.S. International Trade Commission agreed to investigate Segway Inc.'s claim that Ninebot and other companies were infringing on its patents and copyrights. [26] [27] [28] Segway Inc. requested the blocking of imports of competing scooters into the United States. [26] [27] [28]

In June 2016, Segway Inc. launched the Segway miniPRO, a smaller self-balancing scooter. [29]

End of production

Only 140,000 units were sold during the lifetime of the product, and in the later years the Segway PT only made up 1.5% of total company profit. [1] Factors contributing to the end of production include the price (US$5,000 at launch), and the learning curve in learning to balance on a Segway PT which has led to notable accidents involving Usain Bolt, George W. Bush, Ellen DeGeneres, Ian Healy, and the Segway Inc. previous owner Jimi Heselden. [2] While the Segway Inc. has remained popular for security and tourism, electric scooters have been more popular for personal mobility. [1] [2]

UTVs

In February 2022, Segway entered the UTV (Utility Terrain Vehicle) market.[ citation needed ]

Products

At the end of production in 2020, Segway Inc. was selling these five self-balancing scooters:

Technology

The dynamics of the Segway PT are similar to a classic control problem, the inverted pendulum. It uses brushless DC electric motors in each wheel powered by lithium-ion batteries with balance achieved using tilt sensors, and gyroscopic sensors developed by BAE Systems' Advanced Technology Centre. [35]

In 2011, the Segway i2 was being marketed to the emergency medical services community. [36]

In 2018, the police of Stockholm adopted Segway i2 as a permanent transportation method for the patrollers of the old town. [37]

The Segway miniPro is also available to be used as the mobility section of a robot. [38]

Disability Rights Advocates for Technology [39] worked to supply Segway PTs to veterans who had trouble walking. (Segway Inc. cannot market its devices in the US as medical devices. Kamen sold the intellectual property rights for medical purposes to Johnson & Johnson, makers of the iBOT, a self-balancing wheelchair). [40]

The maximum speed of the Segway PT is 12.5 miles per hour (20.1 km/h). The product is capable of covering 24 miles (39 km) on a fully charged lithium-ion battery, depending on terrain, riding style, and the condition of the batteries. [41] The U.S. Consumer Product Safety Commission does not have Segway-specific recommendations but does say that bicycle helmets are adequate for "low-speed, motor-assisted" scooters. [42]
