Background: 

Years from now, along with the continuous development of human civilization, the ecological environment is facing extremely serious damage, such as the over-exploitation of the Earth's resources, wastewater brought about by industrial development, garbage generated by life, etc. You travel with MatataBot to a corner of the Earth, which can be a grassland, forest, mountain, ocean and other places. Here you see heartbreaking situations such as indiscriminate logging, pesticide abuse, sewage discharge, garbage piles and illegal hunting. The local animal friends are living a difficult life and are in great need of someone to help them improve their home environment. Unleash your imagination and turn MatataBot into a brave messenger of justice! The robot is supposed to be modified according to different environments so that it can protect our animal friends in an adaptive way. For example, in a forest scene, you can arrange MatataBot to clean up the bottles and plastic bags that fall everywhere; or remove the traps and bird nets found; or prohibit the offenders from illegal logging and hunting and arrest them; or provide medical treatment to the injured animal friends and send them back home, etc.

Come and start a brave and loving journey of justice with MatataBot!
