The goal of this page is maintaining an updated list of the status of the s-bots in IRIDIA For each s-bot, a short list of hardware/software problems should be given. Every time an error/problem occurs while experimenting with the s-bots, it *must* be recorded here.

Common hardware problems

The following document list common hardware problems and their solutions:

When something happens to the s-bots (French, pdf)

sbot 6 - IN LAUSANNE
