With the development of technology, four-wheel cars with autonomous driving have become common. Have you ever seen a two-wheel driverless bicycle?

According to media reports, recently,Mu Lang, a senior three student from Hangzhou No. 9 Middle School, made a bicycle that could be driven by no one and won the first prize in the Chinese division of qiu Chengtong Middle School Science Award.

As you can see from the video, the driverless bike as a whole is similar to a normal bike, and even simpler and cooler. The difference is that there are depth cameras on the handlebars and lidar on the seat.

Using depth cameras and lidar, the data can be beamed back in real time to the bike above the rear wheel. Central brain & RDquo; .So as to control the balance of the bike, but also to choose the optimal path.

According to Shi Mulan, the most difficult part of the self-propelled bike is keeping the vehicle balanced. In addition, because a bicycle cannot turn freely like a car, it is necessary to analyze the kinematic constraints of front and rear wheels while satisfying the kinematic characteristics of a bicycle.

Finally, in nearly a year, By writing codes, doing simulation experiments, and constantly debugging the system, Shi Mu Lang successfully completed the whole bike project at the end of March last year.

At present, the bike. Central brain & RDquo; Path planning and decision module,The level of the control algorithm is between L2 and L3, comparable to Tesla's autopilot assistance level.
