[robocup-humanoid] Regarding the use of compass in the robot in the rule book

[Ludovic Hofer]

Dear Joshua,

Thank you for your interest, using a compass is currently forbidden in 
the rulebook as you pointed out. Last year, we noticed this issue about 
some teams TDP and we sent them a message to inform them that use of 
compass would not be allowed on site.

This year, we will enforce that team mentioning use of a compass in TDP 
have to correct the TDP in order to be qualified, to avoid any possible 
misunderstanding.

While answering to this e-mail, I must also mention that there are 
currently discussions inside the TC regarding constraints on sensors. 
Therefore, there will probably be updates in the next few months 
regarding the regulations on sensors. If you want to discuss the topic 
further, please open a thread on the league forum: 
https://hl.forum.robocup.org/

Best regards,

Ludovic Hofer
