As reported a few days ago, Vector 2.0s have a massive heat problem. They are generating more heat than a first generation vector and thus show a temp warning early and in completely normal environment temperatures.
The first Vector 2.0s are arriving at customers. So far only in the USA, because … no, that is so incredibly unbelievable and unprofessional, it will get it’s own article.
The Moorebot people said they do not implement SLAM and they let the Scout only run on two of the four cores of the ARM7 CPU because they fear heat problems.
