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

Q16.补弹指令具体指什么呢？
A. It is a protocol command sending to Referee system (from STM32 MCU to Referee system). But in the later robots version, we will provide it in the ROS sdk also. So no worry about this question.

Q18. 请问补给站一次补给的时长是多久？有补给完成的标志吗？
A. Please refer to Q1

arosendo, we are finding a software engineer for you. one moment.

Q19. 请问比赛中什么样的冲撞会判犯规？只要碰到围挡或者障碍就算吗？双方机器人相互碰撞如何判罚？
A. Refer to Rule Manual 3.5.3.1 Attack and Compete (Collision Penalty)

We will receive questions in the last five minute!

Q21. 您好，我们队伍购买了官方车，但是买来的机器人云台是不可控的，请问车上的云台板是完全留待自己开发的吗，还有和github上的官方程序是底层板的程序还是云台板的程序？thank you very much！！
A. Make sure your remote controller is operated in the right mode (refer to AI Robot user manual). And STM32 program is open sourced (RoboRTS-Firmware: https://github.com/RoboMaster/RoboRTS-Firmware icra2019_dev branch). Onboard ROS program is open sourced(RoboRTS: https://github.com/RoboMaster/RoboRTS ros branch)

@happysf128, roughly 1200 USD each unit.

Q20：A question about the "Projectile reservoir". I know that we should extend it, but the big question is: Is there any limit on how much bigger can it be? I assume that as long as we respect the 600x600x500 constraints we are fine?
A. Only need to meet the referee system inspection specifications，Refer to Rule Manual Appendix Four - Pre-match Inspection Form

Q23. In the current ROS API, how can we control the firing action? What is the topic for that?
A. /cmd_shoot (roborts_msgs/ShootCmd)
service command of projectile launching（including mode, freq and number) Refer to https://robomaster.github.io/Rob ... k_docs/roborts_base (English version will be released in days)

Q25. Another question is regarding the Proposal. We built the arena and even sent a video with results of our Localization and Planning running AMCL and A* on that same arena, and also YOLO fully functional on our robots. After receiving a B we hear as the reasoning for that grade that "Localization, Planning and Vision were insufficient". Is it possible to ask for a reconsideration on the report?
A. please send an e-mail to robomaster@dji.com with uni & team name, thanks~
