WeRide Robobus in Guangzhou, China
|Manufacturer||Yutong / WeRide|
|Years in operation||Late 2023 (TBC)|
|Emission Standard||NA (Zero tailpipe emissions)|
The WeRide Robobus, also known as the Yutong Xiaoyu 2.0 (小宇2.0), is an autonomous driving shuttle developed through a collaboration between the Chinese start-up WeRide and the bus manufacturer Yutong. The names “WeRide Robobus” and “Yutong Xiaoyu 2.0” are used interchangeably by different entities involved in its promotion and development.
Under an agreement with Strides Mobility, WeRide will be trialling autonomous vehicles such as its minibus, taxi and road sweeper in Singapore later in 2023.
The WeRide Robobus is touted as the world’s first fully-driverless shuttle capable of SAE Level 4 autonomous driving. This means that the vehicle can reliably manage most driving conditions completely autonomously, and is able to automatically stop safely in the event of adverse conditions (e.g. severe weather) rather than requiring an operator to take over. The vehicle is designed and built by
Road trials of the Robobus were conducted in multiple Chinese cities. In January 2022, the service was launched to the public for the first time in Guangzhou, with two routes serving public roads on Guangzhou Bio-island daily. The vehicle speed is limited to 40 km/h during operation. As of 2023, the RoboBus has been deployed to 18 cities across the globe, mostly in China.

Vehicle Background & Onboard Technologies:
In 2019, Yutong introduced the Xiaoyu autonomous minibus, capable of SAE Level 4 autonomous driving. An updated version, Xiaoyu 2.0 (小宇2.0), was subsequently released in 2020. Around the same period in December 2020, Yutong made an investment in and formed a collaboration with the self-driving startup WeRide. This collaboration aimed to further advance the technology, which led to the development of the WeRide Robobus. Functionally, both the Xiaoyu 2.0 and the WeRide Robobus are the same vehicle, derived from the collaboration between Yutong and WeRide.
The bus incorporates LiDAR technology to detect objects in three-dimensional space within a range of 250 meters with no blind spots. High-definition cameras are utilized to identify road markings, traffic signals, pedestrians, and vehicles. In addition, millimetre-wave radar is employed to precisely measure the distance, speed, and directions of surrounding objects, enabling all-weather operation.
Vehicle localisation is achieved through a combination of GNSS (Global Navigation Satellite System), IMU (Inertial Measurement Unit), and LiDAR, resulting in real-time localization with an error margin of less than 10 centimetres. WeRide asserts that the vehicle can effectively operate in adverse weather conditions and navigate through tunnels spanning kilometres, even in the absence of a GPS signal. Beyond onboard sensors, 5G-enabled low-latency V2X communication allows the vehicle to communicate with roadside sensors for enhanced situational awareness.
In 2021, Yutong won the 2021 Red Dot Award for the design of the Xiaoyu 2.0, the first Chinese bus manufacturer to have received this award.
