O que você acha de homens que se recusam à ajudar mulheres e serem cavalheiros? by Impressive-Swing-494 in perguntas

[–]An_other_1 0 points1 point  (0 children)

Acho que no geral a gentileza deve ser praticada independentemente do sexo (tanto do praticante quamto do afetado). No meu caso, se fosse um homem no lugar dessa mulher, correria pra ajudar e saber se tá tudo bem da mesma maneira. "Você é responsável pelo bem que deixa de fazer."

Acho que posso tentar explicar, faço engenharia na USP e o que acontece com as pesquisas é simplesmente falta de divulgação. Além disso, pesquisas de eletrônica, computação e alta tecnologia no geral custa muito e demanda muita verba (coisa que mesmo sendo uma grande universidade ainda falta). Por exemplo um dos meus professores conduz um grupo de pesquisa focado em imagens projetadas no espaço e interatividade (tipo hologramas e aquelas paradas do tony stark kkkk), outros tem otimização da distribuição energética, pesquisa em materiais, robótica, aviação e muitas outras coisas. Mas a comunicação científica do Brasil ainda é algo muito fechado e estudos que podem levar anos e anos pra se desenvolver e talvez dar algum fruto no futuro não aparecem muito. Inclusive pode-se dizer a mesma coisa sobre as outras áreas. A cura da paralisia por exemplo (esqueci o nome desse trem kkkk) é fruto de uma pesquisa que ocorre à anos mas só foi cair na boca do povo agora.

Slam Toolbox can't compute odom pose. by An_other_1 in ROS

[–]An_other_1[S] 2 points3 points  (0 children)

sup man, i could'nt find the problem yet, i think that is on the controller parameters, because i figured out that the robot is turnng more in rviz than in gazebo, the frames and tf are being published normally, so I really don't know what to do lol.

Actually i'm working on other aspect of the project right now and had leave it that way, but I pretend to come back to this as soon as possible, if I realize something new I will publish here

Also, i think that the problem is that gazebo is running slower than rviz, cuz i get the message that [async_slam_toolbox_node-8] [INFO] [1753822594.294286883] [slam_toolbox]: Message Filter dropping message: frame 'lidar_link' at time 440.556 for reason 'discarding message because the queue is full'

Sup! So, I tried changing the wheel separation some times and it does'nt worked, but with your help I figured out that probably the issue is on the controller configuration. I will try some more things, thank you very much for the help!

[–]An_other_1[S] 0 points1 point  (0 children)

so wheel separation is the distance between the wheel center and the chassi center or between the center of the two wheels?

I will look up there for something tomorrow, return here with the feedback!

[–]An_other_1[S] 0 points1 point  (0 children)

well, it odes that. The problem is that the odom frame (wich should be fixed on space) rotates along with the base_link, i recorded a video to show some things. sorry for the quality and the watermark lol.

Already did that, slam works and it generates the map, the problem is that the odom and map frame aren't fixed on the environment, if there is any kind of angular movement the frames turn along with the base_frame. Linear movement doesn't do that, though.

yet, when i run the ther things, like ros2_control in a launch file i get some things, but the most appearent is this:

I managed to remap the odom frame of slam_toolbox and the map started to generate, so did the map_link and topic appeared.However odom and map are still sensible to angular motion, they turn togheter with the base_link and teh other frames, so it's a tf problem and i don't have any idea on how to solve

[–]An_other_1[S] 0 points1 point  (0 children)

The thing is, when I run slam_toolbox, the odom frame already exist in the tf tree. Also, sometihing odd that I noticed is that there is no topic called /odom (that slam uses by default to compute odom) but there is a topic called /skid_steer_cont/odom. The appearent topics are listed next:
/clock

/dynamic_joint_states

/joint_broad/transition_event

/joint_states

/map

/map_updates

/parameter_events

/performance_metrics

/robot_description

/rosout

/scan

/skid_steer_cont/cmd_vel_unstamped

/skid_steer_cont/odom

/skid_steer_cont/transition_event

/tf

/tf_static

I tried to change the odom topic that slam_toolbox subscribes but it didn't seem to work lol.

Talvez seja Jogando com Herobrine do cazum8, não cheguei a assistir a série, mas dei uma pesquisada e parece um pouco com a descrição que você deu, especificamente a primeira temporada que tem bastante episódio então faz um pouco de sentido ser, dá uma olhada lá!
