Which type of Machine Learning is used in robots? Is it supervised learning or unsupervised learning or Reinforcement learning? Especially the robots that were sent in space?
Robotics primarily uses RL and supervised learning. To give examples:
Supervised Learning is used for vision and perception
Reinforcement Learning is used for control
Unsupervised Learning for robotics is less commmon, but I am sure exists.
