racecarj / installracecarj Goto Github PK

Hello,

Is this fully autonomous car? or is there a some built in features to switch it to manned? while leaving the computer manage collision avoidance and things like that?

Suppose I build a hardware car/platform exactly the same as MIT racecar and install their software successfully. Can I run the car autonomously everywhere? I have a course I would like to car to run, do I have to train the car again?

I am trying to build the racecarj ros on Xavier NX. Everything seems to work except the joy_teleop node. I got the following error message:

ERROR: cannot launch node of type [joy_teleop/joy_teleop.py]: joy_teleop
ROS path [0]=/opt/ros/melodic/share/ros
ROS path [1]=/home/nvidia/racecar-ws/src
ROS path [2]=/opt/ros/melodic/share

when run

roslaunch racecar teleop.launch

Anyone had the same issue?

Hi, I am setting up Hokuyo UST 10LX on my Jetson TX2, but got confused about the ROS/Hokuyo/TX2 ip addresses. Hope you can help me clarify it.

Hokuyo ip address is factory default: 192.168.0.10 and it is linked to the Ethernet port of the TX2. I followed the instructions in this https://www.jetsonhacks.com/2018/02/2... and set my TX2 eth0 to 192.168.0.15.

However, my jetson uses WIFI and its ip address for wlan0 is 192.168.0.28. Since my TX2 is attached to the car, I want to open rviz on another computer so I can monitor the data from the TX2. The other computer is also on WIFI and its ip address is 192.168.0.29.

My questions is what the ROS_MASTER_URI and ROS_IP on my TX2 should be?

Thank you very much.

Will there be an update to these install scripts for 28.2?

I built a Racecar J and could use teleop to drive it. I found, however, my car always turn right a little bit, even when I drive it straight. I think the steering is not centered. Is there anything I can tune with the BLDC tool? Or I have the tune the car mechanical parts?

It looks like racecar-v2 doesn't include ROS nodes for any cameras (ZED, structure.io, realsense, or whatever). Any plans to add this back in?

In the file installZED-SDK-TX2.sh there is a wget line:

wget https://www.stereolabs.com/developers/downloads/archives/ZED_SDK_Linux_JTX2_v2.2.1.run

It appears the ZED folks have moved this archived run script

I now manually download from:

https://www.stereolabs.com/developers/release/2.2/

Is there a way to update your installZED-SDK-TX2.sh file for this?

If I upgrade my Jetson TX2 to jetpack 4.1, what changes are need to make repo work?

Is any thoughts or work underway to release a fork of this to install ROS on the Jetson Nano jetracer, https://github.com/NVIDIA-AI-IOT/jetracer that uses a reworked Traxxas Latrax Rally, not unlike the MITRacer?
