Practical exercises week 1:
1. On the robot-laptop open rviz. Observe the laser data. How much noise is there on the laser? What objects can be seen by the laser? Which objects cannot? How do your own legs look like to the robot.
The laser data shows with point clouds highlighted in red where objects are. In a constant environment the laser data is still quite fluid and dynamic. This indicates that there is significant noise on the robot. As of our own legs, they are visible as two small rectangles.
2. Go to your folder on the robot and pull your software.
This has been done.
3. Take your example of don't crash and test it on the robot. Does it work like in simulation?
After significant tweaking and updates, yes the simulation works.
4. Take a video of the working robot and post it on your wiki.
Video below:
