hypha-ros / hypharos_racecar Goto Github PK

Hello! I am having this error continuously while running Test_gmapping.launch file. Btw I am new to ROS and trying to build your project.

Any help will be highly appreciated.

Where can we buy all the parts to build the car hardware? I live in the US

找不到文件imu_auto.py

Timed out waiting for transform from base_footprint to map to become available before running costmap, tf error: canTransform: target_frame map does not exist.. canTransform returned after 0.100223 timeout was 0.1.
查看了一下 rosrun tf view_frame map跟odom沒有被amcl發出

First of all, thank you for maintaining this repository 👍 . I am building a 1/10 scale autonomous but I am constrained on budget. This repository is exactly what I needed.

I was looking at the Hypha ROS RaceCar Tutorial V1.1.pdf and I noticed that you use an Arduino Nano as an interface between the GY85 IMU and Odroid XU4. If I use a Razor 9DOF IMU which has a micro USB slot, can I simply use a microUSB to USB connector and connect the IMU to the USB hub?

Hi,I wonder if / move_base_node/NavfnROS/plan belongs to global_planner?
And I couldn't find the location in the code where it was published，I hope you could solve my problem.

When the racecar have a greater acceleration to speed up or brake, the odometry will drift even when it is still after applying the brake. So I check the odometry got from rf2o, and it drifts. I wonder have you ever met this problem and how to deal with it?

Here are my 2 question
(1)I have" HSP 94186" rc car , it is "1/16" scale , hardware similar to "HSP 94123" but it's small scale. I want to know can i use "HSP 94186" instead of buying "HSP 94123" . I know it is smaller but i can manage with hardware intergartion.
(2)Have you change "HSP 94123" stock -esc with "TAMIYA ESC TBLE-02S" ,steering servo with
"FUTABA S9151 digital servo" and battery with "7.4v 5000 Mah battery"or you bought a empty 1/10 car frame and added all this parts mentioned in build doc pdf-"https://github.com/Hypha-ROS/hypha-racecar/blob/ver.1-release/document/Hypha-ROS-RaceCar-Tutorial_V1.1.pdf"

hi I am trying to upload the code to the arduino nano but it is giving me all these copy error messages. I'm kinda new to arduino and I was wondering if anyone knew how to solve it.
Thank you

Its not working,it show error.

Hello! So now i try to make and build race car V.1 based on your tutorial workshop. I want to ask, i have ESC TBLE-02S before but the motor can't move forward (just backward, right, and left). When i tried to troubleshoot, then the ESC broken and burned inside. So do you know what happen and why?
And By the way what is your brushed motor name and type that you used?

您好:
首先，我發現mapir-ros-pkgs這個pkg已經不支援而且catkin_make會報錯，所以我使用rf2o_laser_odometry這個更新過的pkg可以成功編譯ws.

之後我按照toutorial_V1.1 replace rf2o檔案卻無法再次成功編譯ws.
Error顯示在CLaserOdometry2D.cpp 這個取代過的檔案.
我想是否因為其他pkg的更新導致取代檔案已經無法使用?請問我該如何修改呢 謝謝!

Hi! Thanks, I followed all of your steps in the tutorial pdf. But when I running navigation, the robot can't move backward, isn't it? So, is it possible to move backward when running navigation? How? and can I change or upgrade in any code to do that?
Thank you!
Hope you can answer this question

Hi,

I am using RPLidar A1. Your tutorial recommends using a separate power supply for the motor. The motor supply has 3 pins - GND, VMOTO and MOTOCTL. VMOTO is DC voltage between 5-10 V. MOTOCTL is the PWM control signal for the motor. Here is a screenshot from the datasheet.

The PWM signal is generated by the circuit board provided by Slamtec (manufacturer of RPLidar).

However I noticed from your tutorial that you are using only 2 pins (RX/TX) from the board. See this:

Your block diagram also suggests 2 pins.

Initially I thought that if I don't connect the MOTOCTL pin then maybe the motor will run at its default speed. However when I tried this the motor did not start. How are you generating the MOTOCTL PWM?

hi when i try to run the catkin_make comand at the end of the 'Initial Settings' page in the tutorial, I get this error:

any help?

Hi i'm trying to establish the power connection for the odroid, however i'm having issues because it can't connect to the vcn. I am using virtual box, does that have anything to do with it? what could be wrong?

thank you

May I ask why the variable Lfw equals to (Vcmd2.24)/3.
I learnd from other pages that selected Lfw = Vcmd2.24.
Thank you so much , I am confused a lot. Looking forward to your answer！！

Hi@jim
when will docker or virtualbox OVA file for racecar be provided.

When my racecar is running, in rviz, the obstacles scanned by radar often change (because the car is moving), but the footprint of the car does not move,And no problem of TF transformation has been found.I guess there is a problem with rf2o, but there is no solution yet. Do you have any suggestions?

Hello I used roroslaunch hypha_racecar RACECAR_bag_gmaping.launch
[ERROR] [1604471409.129055131]: "base_footprint" passed to lookupTransform aggregate target_frame does not exist. This error occurs.
I don't know what to do. Please help me.

hi when I type 'https://github.com/cra-ros-pkg/robot_localization.git' in the terminal I get this response:

remote: Repository not found.
fatal: repository 'https://github.com/cre-ros-pkg/robot_localization.git/' not found

why is this happening?

thank you
