Based on a conversation last night i was being asked about good robot kits to help learn about building robots for piwars and sumo robots.
These are nice tiny kits they had them at piwars 2017, and they are quite nicely priced
what do others recommend ?
Another option but its sold out currently, may find it else where.
This issue of mag pi has some good info, also mentions the pi wars challenges.
Just found this, looks like quite a nice kit.
