Colobot Wiki

A tracked bot designed to protect and defend against all enemy attacks within a perimeter of 10 to 25 meters. The individual shields of bots and buildings are re-energized through the shielder's defensive actions. This bot is the only way to get through narrow passages adorned with poisonous green mushrooms.

A regular power cell allows for a 20-second activity span with a radius of 25 meters, much too short in most cases. A nuclear power cell is of course more suited to this bot.

The energy consumption is proportional to the radius of the protective sphere. With a radius of 10 meters, the bot can work 2.5 times longer than with the maximum radius of 25 meters.


  • The shielder is currently the only way to repair damaged buildings.
  • A shielder will not protect itself or other bots from lava.
