SBOT STATUS

What is this page?

This page contains an up to date list of the status of the IRIDIA sbots. Please update with any problems or other info you find for each s-bot.

Please note that robots with trembling turrets, different track speeds and broken slope sensors are not considered to be "broken". Only robots with major problems like broken tracks or LEDs are marked as broken in the following list.
