When considering automation apps for Android, Tasker immediately comes to mind. And although it has name recognition, it's source code is proprietary and the app requires the Google Play store on the device (beyond a 7-day trial version).

So, what FOSS automation apps are there out there?

• Easer by Rui Zhao. Source on Github (449 stars, 1295 commits), F-Droid. Note that there is also a beta version of this app.
• Automation by Jens Schröder. Source on developer's Gitea instance (88 commits), F-Droid.

Other non-free automation apps for Android (not recommended)

• Tasker
• Automate by LlamaLab
• AutomateIt
• MacroDroid
• RuleBot by KF Software House (Hong Kong)

Two wheels

Cargo bikes

• Xtracycle, extra sturdy electric bikes with longer-than-normal rear wheelbase to carry two children or lots of cargo.
• Convercycle, a bike that transforms to cargo bike, via Core77

Three wheels or more

• Electric tricycle that leans into corners, a concept from BMW (not produced yet). Cargo area between the two rear wheels, and the front is able to tilt in curves. Chain-based drive mechanism that looks complicated.
