【ICRA2019 AI Challenge Live Text Tutorial Session with Q&A】

Should all the processing take place on the robot itself?

3.        Test the robot driver on the onboard PC, make sure the robot is placed in the OPEN and SAFE area:

suraj, question received, will answer it later.

Can we know the exact size of the Manifold2, worrying about the choice of other onboard computers?

a)        According to the tutorial, install the software dependencies, compile the robots packages and configure the udev rules on your onboard PC.
b)        Stay on manual mode for remote controller, run the roborts_base_node with Rviz under ROS. Use the remote controller to control the robot, and check if you can get the correct odometry and transform topics.
c)        If everything goes well, publish topics for gimbal or chassis control and switch remote controller to autonomous mode. Check if the robot moves correctly.

how to win the champion ^_^

Here is some new information for the competition:

1.        In the mid-February, we will release detailed mechanical drawings about game field including projectile supplier and protective perimeter wall. And the wall of the projectile supplier will be attached with the certain marker.
2.        RoboMaster organization will not provide a standard simulator for the game this year.
3.        The communication between robots through the referee system is still under development and is supposed to finish on Mid-March. So teams had better build your own wireless communication link.
4.        We will be glad to hear from teams for the definition of robot illegal behaviours that would take advantage of loopholes in the rule but no more help the inspiration and development of technology. The rules will forbid such behaviours by common consent.

now we start answering questions.

A question realated to RoboMaster Winter Camp #LOL:

Without UWB or any other position systems like RTK, what is the best way to get the absolute position in the arena?
I am trying to do that with feedbacks from chassis encoders, which are not always expected.
