Before revision:  At test time, we study the performance of our learned policy on two new legged robots  (Laikago, 4-legged Daisy) and show that our learned policy can sample-efficiently generalize to previously unseen  robots.
After revision:  At test time, we study the performance of our learned policy on two new legged robots (Laikago, 4-legged Daisy) , and one real-world quadrupedal robot (A1). Our experiments show that our learned policy can sample-efficiently generalize to previously unseen robots.
