bug in climbing and descending stairs

[bottlele]

Hello, in this project, using pre-trained weights works fine for climbing stairs, but when descending stairs, the model tends to step on the edge at the second-to-last step, leading to a fall. How can this issue be resolved? Thank you for your reply.

Hi, have you face the problem that the robot can not climb a single step, just stepping inplace?

My previous issue was about passing directly through the stairs instead of walking on them.

This issue I encountered before, may be you can check your mujoco version, the version should be 2.2.x

Maybe we can communicate more deeply about this project. Feel free to contact me through yinkn2022@shanghaitech.edu.cn

I see you are in Shanghai, are you Chinese?

请问您程序里mujoco和dm-control的具体版本是多少呢？我这边运行的话，楼梯显示不出来

@bottlele what command do you use to run up the stair using pretrained weights? also the command for running down the stairs shows different scenarios- walking sideways etc- on running it each time show different scene
