Many Robotic Process Automation (RPA) vendors provide free tutorials and also allow you to download their tools.

Here are some free mainstream and Open-source tools with useful links.

Mainstream Tools

One of the most widely used (as suggested by others too) is UiPath. UiPath is easy to learn and get started. You can download the tool, learn from their academy and get rolling in no time. There is a decent community to support as well.

TagUI does not use flowcharts but “human language” like Command line syntax to automate. So, you tell it things like this: click login; type username as xyz etc. You can also do Visual automation for Websites and Desktop.
