Hi, This project uses multi-channel Lidar. We squash the 3D measurements into 2D to create a single dimensional vector for input into the TD3 network. Direct multi-channel input is also possible in theory. But this project does not support that. Here, only single dimension inputs are supported out of the box. |
OK, thank you for your reply. It is helpful for me. |
Hi, Please provide more information about the issue. What do you mean it cannot move? Is there an error or does the network not produce an output? Quick note is that in your callback you are using a point_cloud2 function but your message type is PointCloud instead of PointCloud2. But in general, these kinds of changes are outside the scope of this repository and I would not have the time to investigate such in depth changes. Good luck! |

Hi! Just fixed this problem and found someone has encountered the same problem. In velodyne_env.py there's a "self.last_odom" which is init with "None", if you change "self.last_odom = None" into "self.last_odom = Odometry()" the attribute error will be solved. (At least for me) |
Hi, thank you for your reply. I have solved the problem. Could you tell me what the reason is? |
Hi, Initializing with Odometry() will solve the symptom but not the issue. The reason why this error appears is that there has been no odometry published to the topic that you subscribed to. So the callback does not get triggered and value for I assume this issue arises for you because of one of two reasons:
|
It is simply the height from the ground at which you have set your sensor (plus some buffer value) |
Hi,
This project uses a single-line Lidar. I would like to ask if multi-line Lidar is feasible.
