# Build
```
mkdir -p ~/mevius_ws/src
cd ~/mevius_ws/src
git clone git@github.com:haraduka/mevius.git
cd ..
catkin build
source ~/mevius_ws/devel/setup.bash
```

# Reinforcement Learning
Caution: This policy is very simple and not so stable. Currently, it became very stable with a lot of improvement and will be uploaded soon.

```
# in legged_gym
git remote add haraduka git@github.com:haraduka/legged_gym.git
git fetch haraduka
git checkout haraduka/mevius

# train with two phases
# first phase
python3 legged_gym/scripts/train.py --task mevius
# second phase
# change the parameters in legged_gym/envs/mevius/mevius_config.py from "first" to "second"
# there are two parameters to change: commands.ranges and domain_rand.friction_range
python3 legged_gym/scripts/train.py --task mevius
python3 legged_gym/scripts/play.py --task mevius --load_run ( log_dir )
cp logs/flat_mevius/( log_dir )/exported/policies/policy_1.pt ../mevius/models/policy.pt

```

# Usage
Please test the installation by running the following command.
```
python3 scripts/mevius_utils.py
```
Please test the motors by running the following command.
```
./bin/can_setup.sh
python scripts/tmotor_test.py --ids 1 --task sense
```
Please test the real robot by running the following command.
```
# in the PC of MEVIUS
roscore
roslaunch realsense2_camera rs_t265.launch
./bin/can_setup.sh
python3 scripts/mevius_main.py

# in your local PC
roslaunch spacenav_node classic.launch

# Left Click: SITDOWN/STANDUP, Right Click: STANDUP/WALK

# if you want to simulate the robot in mujoco
python3 scripts/mevius_main.py --sim

# please press D to turn off every-step rendering in mujoco viewer
```
