Japan electronics giant Hitachi unveiled a pint-sized roller-skating robot yesterday that can negotiate uneven surfaces, respond to voice commands and could work as a tour guide or security guard.
Dubbed the EMIEW2, the humanoid has complex spring-loaded shock absorbers in its legs that allow it to move across minor bumps and wires on the floor without tripping, a world-first for a robot of its kind, the company said.
“It can control its posture the way humans do when we stabilize ourselves after jumping on inline skates,” Yuji Hosoda, chief researcher at Hitachi’s transportation systems department, said at the robot’s Tokyo launch.

The machine, 80cm tall and weighing 14kg, has 14 microphones fitted into its helmet that can pick out human voices from background noise such as music or the clatter of footsteps.
Fitted with wheels on its two legs, it moves at a maximum six km an hour, a fast walking speed for a human adult.
The red-and-white robot could be used as a receptionist and visitors’ guide in office buildings, Hosoda said.
“It could also be used for security, such as patrolling and surveillance as it could find a suspicious person hiding in blind spots out of range of fixed security cameras,” he said. “This adorable EMIEW could lead to a new form of surveillance.”
The company has not yet announced plans to commercialize the robot.
The name EMIEW — although its sounds like Australia’s flightless bird the emu — is short for “excellent mobility and interactive existence as workmate,” Hitachi said.
The Chien Feng IV (勁蜂, Mighty Hornet) loitering munition is on track to enter flight tests next month in connection with potential adoption by Taiwanese and US armed forces, a government source said yesterday. The kamikaze drone, which boasts a range of 1,000km, debuted at the Taipei Aerospace and Defense Technology Exhibition in September, the official said on condition of anonymity. The Chungshan Institute of Science and Technology and US-based Kratos Defense jointly developed the platform by leveraging the engine and airframe of the latter’s MQM-178 Firejet target drone, they said. The uncrewed aerial vehicle is designed to utilize an artificial intelligence computer
The Chinese Nationalist Party (KMT) caucus yesterday decided to shelve proposed legislation that would give elected officials full control over their stipends, saying it would wait for a consensus to be reached before acting. KMT Legislator Chen Yu-jen (陳玉珍) last week proposed amendments to the Organic Act of the Legislative Yuan (立法院組織法) and the Regulations on Allowances for Elected Representatives and Subsidies for Village Chiefs (地方民意代表費用支給及村里長事務補助費補助條例), which would give legislators and councilors the freedom to use their allowances without providing invoices for reimbursement. The proposal immediately drew criticism, amid reports that several legislators face possible charges of embezzling fees intended to pay
REQUIREMENTS: The US defense secretary must submit a Taiwan security assistance road map and an appraisal of Washington’s ability to respond to Indo-Pacific conflict The US Congress has released a new draft of the National Defense Authorization Act (NDAA), which includes up to US$1 billion in funding for Taiwan-related security cooperation next year. The version published on Sunday by US House of Representatives Speaker Mike Johnson removed earlier language that would have invited Taiwan to participate in the US-led Rim of the Pacific Exercise (RIMPAC). A statement on Johnson’s Web page said the NDAA “enhances U.S. defense initiatives in the Indo-Pacific to bolster Taiwan’s defense and support Indo-Pacific allies.” The bill would require the US secretary of defense to “enable fielding of uncrewed and anti-uncrewed systems capabilities”
Renewed border fighting between Thailand and Cambodia showed no signs of abating yesterday, leaving hundreds of thousands of displaced people in both countries living in strained conditions as more flooded into temporary shelters. Reporters on the Thai side of the border heard sounds of outgoing, indirect fire yesterday. About 400,000 people have been evacuated from affected areas in Thailand and about 700 schools closed while fighting was ongoing in four border provinces, said Thai Rear Admiral Surasant Kongsiri, a spokesman for the military. Cambodia evacuated more than 127,000 villagers and closed hundreds of schools, the Thai Ministry of Defense said. Thailand’s military announced that
