Raspberry Pi conference
The Pi Wars competition has an online conference coming up on Saturday 23rd & Sunday 24th of January. Tickets are free and there is a packed schedule of experts talking about a range of robot related topics. You don't need to sit through the entire weekend but can dip in and out when you have time. It should be really fun and informative.
