Building a Full-Sized Self-Driving Car in 5 days (Part 1)
This week (22 May) I have come to GuiYang in China for the Moving Hackathon 2019 Self-Driving Global Challenge and the experience is amazing.
The challenge happens in a factory inside the Technology and science industrial park.
There are two groups of challenge
- Full-sized Self-driving Car
- DIY Robocars Donkey Car
Obviously I am coming to join the Donkey car challenge and I even brought my new shiny Jetson Nano on Donkey Car to join the race. Despite the Donkey Car challenge starts on 25 May, I decided to come earlier to check out the full sized car challenge. It turns out to be really interesting.
Each team is given a full-sized car equipped with an onboard computer, a box developed by PIX Moving that connect the onboard computer to the car computer, a Velodyne LiDAR and a camera.
These are 7 missions for the full size car challenge:
- Traffic Light Recognition
The car should stop before the stop line when the traffic light turns red and should move forward when the light turns into green.
2. Pedestrian Avoidance
The car should slow down to full stop when there is a pedestrian walking on the zebra crossing. After the pedestrian crosses the road, the car continues to drive.
3. Lane-changing, Slow-down and Stop on slope
The car need to switch from the left lane to the right lane and stop for 3 seconds. After that, the car turns right and drives forward.
4. Obstacle Avoiding (Non-stop Driving)
Some road block will be placed on the right lane. The car need to avoid the obstacle without stopping.
Just make a U-turn. Sounds easy but if the computer can’t complete within a single attempt, it probably don’t know how to reverse and complete the turn.
6. Stop Sign Recognition
During the test, two sign (Stop and blank) will be switched interchangeably by the staff. The car will need to recognise the correct sign to do the right action.
7. S-Bend Driving
The car should drive through the area without hitting the traffic cones.
On the first day, the teams were given briefing on the hardware and install ROS and AutoWare. On day two, they start collecting data and working on the challenges. Personally I think the stop sign and traffic light would be the first I would work on as they seems to be the easiest among the missions. I will write more on this later when the teams make some progress.
