BSL-Plotter

Environment

• Ubuntu 20.04
• docker, docker-compose

[NOTE] This repository DOES NOT support NVIDIA graphic driver.

Installation

Hardware

The BSL-Plotter parts are in the bsl-plotter/stl directory. Please refer to URDF model and above image for assembly. And, use 6mm BB-bullets-ball to assemble the thrust bearings. (3D model for assembly will be uploaded soon!)

It is recommended to use a 3D printer to create the parts. The recommended printing conditions are as follows.

• Nozzle: 0.4mm
• Filament: ABS, PLA, PETG
• Support: enable
• Wall: 0.6~1.0mm

Software

1. Clone this repository

   git clone --recursive https://github.com/kim-xps12/bsl-plotter.git
   

2. Launch docker container

   cd bsl-plotter/docker_ros
   docker-compose up -d
   

3. Execute a command in a running container

   docker-compose exec mynoetic /bin/bash
   

4. Check GUI

   xeyes
   

5. Check OpenGL

   glxgears
   

6. Enjoy your robotics!

ROS

You need to operate inside a docker container (mynoetic). It is required to be able to use multiple terminals using tmux or terminator. I recommend reading "How to use Terminator" in the Reference section.

1. Go workspace

   cd catkin_ws
   

2. Build workspace and load settings

   catkin build
   source devel/setup.bash
   

3. Launch rviz

   roslaunch bsl_plotter_description display.launch
   

4. Add new pane, and Launch IK solver

   roslaunch plotter_controller test_swing.launch 
   

5. Add new pane, Run servo driver

   rosrun plotter_controller feetech_driver.py
