    Not in this case. With SpaceX they also need high (de-entry, Mach heating) and low temperature (cryo fuel & oxygen) resistance but in the case of Boom the surface won’t heat enough…

    We actually have very cheap and pretty powerful position-controlled actuators (hobby servo motors). Attach any kind of spring and displacement measurement device (potentiometer, ha…

    Sad to hear, I demoed a system with a Tobii sensor and it performed very well (even with my glasses). We were wondering about the effect of the constant IR blasts (are they continu…

    the real question of course would be how to train the AI to have varying levels of "expertise" (ie: penalize if score is too high)

    Very interesting, thanks for the share. One point I noticed not mentioned yet is that the images used for training are only 64x64! In the original google "grasping" research, the i…

    I think this is mainly a "data" challege, how does Udacity plan on gaining an upper hand on this, especially with competitors like Uber and Tesla which gather data exponentially wi…

    Do you know how long it took to train using that dataset and with what hardware configuration?

    I would say: automation & AI: - automated cities & robotic workers - HARC working on the interfaces for the "workers" - basic income to replace minimum wage earners' incomes Would …
