Sit down, Spot: Robot dog from China's Unitree tops Boston Dynamics rival in payload
Called the A2, the robot dog can withstand an adult standing and even hopping on it, according to a video published by the company on social media on Tuesday.
When in motion, the unit's payload falls to 25kg, but that outperforms rival four-legged robot Spot from US-based Boston Dynamics, which has a maximum payload of 14kg, according to specifications. Unitree said the A2 was suitable for 'logistics, industrial inspection and emergency rescue' in 'extreme and complex environments'.
Constructed from aluminium alloy and high-strength engineering plastic, the machine was designed for demanding environments, Unitree said. In the video, the dog somersaults down stairs, hops on two legs, spins while supporting itself on one leg and rushes down steep slopes.
The unit could operate for three hours when fully loaded, which could extend to five hours when unencumbered, Unitree said. Spot has an average runtime of one and a half hours and a standby time of three hours.
Both models can operate in temperatures between minus 20 and 55 degrees Celsius, but the A2 can climb a slope of 45 degrees, better than Spot's maximum of 30 degrees.

Indian Prime Minister Modi ‘set for first China trip in 7 years' amid Trump tariff row
Indian Prime Minister Narendra Modi will visit China later this month, according to media reports, as the thaw between the two countries gathers pace at a time when New Delhi's relations with the United States have been hit by growing trade tensions. Advertisement Modi will visit between August 31 and September 1 for a Shanghai Cooperation Organisation (SCO) summit in the northern city of Tianjin, according to multiple Indian outlets. Ties between the two Asian giants have seen a steady improvement in recent months after a deadly clash along their disputed border in 2020 brought relations to their lowest point in decades. It comes amid growing strains between India and the US – including this week's announcement of 50 per cent tariffs – that have prompted speculation New Delhi may shift its approach towards China. Advertisement The foreign ministries in Beijing and Delhi have been asked for comment.

Taiwan cyberattacks ‘below average' but widespread, Beijing political advisor says
Taiwan 's collection of cyberhackers may not be sophisticated, but they are 'diligent' when it comes to executing attacks on various mainland Chinese targets, according to one of the country's top cybersecurity experts. Zhou Hongyi, chairman of cybersecurity company Qihoo 360 and a member of the Chinese People's Political Consultative Conference , China's top political advisory body, said in an interview with Hong Kong-based Phoenix TV that aired on Wednesday that Taiwanese hackers operated at a 'below global-average level'. 'They take advantage of the fact that many of our organisations neglect security and fail to apply patches, so even old vulnerabilities can still work for them,' he told the media outlet during an internet security conference in Beijing. 'Their only real advantage is their diligence. They launch attacks on the mainland very frequently and target a wide range of organisations, which is why we've collected the most evidence against them,' Zhou was quoted as saying on the conference's sidelines. Zhou Hongyi, chairman of China's Qihoo 360, speaks to media in Beijing in March: Qihoo 360 was among several Chinese firms added to the US Entity List in 2020. Companies listed on the trade-restriction register have been deemed by Washington as a threat to US national security or foreign policy. Once on the list, the firms cannot receive American goods and technology without a special licence.

China plots pathway to tech supremacy through brain-computer interfaces
China has unveiled a road map to achieve critical technological advances by 2027, with brain-computer interfaces (BCI) playing a pivotal role in the nation's tech rivalry with the United States. Seven ministries, including the Ministry of Industry and Information Technology, jointly released a policy blueprint on Thursday providing innovation and implementation guidelines for China's BCI industry. The document mandates that breakthroughs in key technologies – such as electrodes, chips and integrated products – reach advanced international standards by 2027. While global attention has centred on Elon Musk's Neuralink , China has been quietly advancing a state-backed neuroscience revolution. China aims to position itself among the top global BCI innovators by 2030 and cultivate two to three global industry leaders in the field. The policy frames BCI – a frontier technology merging life sciences and information science – as a critical battlefield in the US-China tech rivalry. Chinese research teams have already established various technical approaches across non-invasive, semi-invasive and invasive BCI categories.
