The robot includes a wheel-leg portion and a base portion connected via a joint. The robot receives a motion instruction and controls a torque of the joint to allow the robot to perform the somersault. During a takeoff phase of the somersault, a center of mass of the wheel-leg portion is lower than a center of mass of the base portion. During a flight phase, the center of mass of the wheel-leg portion is higher than the center of mass of the base portion at some point in time. During the landing phase, the center of mass of the wheel-leg portion is lower than the base portion. This can enable the robot to avoid obstacles.

Abstract: Machine-learned prediction of a blame frame of a crash stack. Specifically, a crash stack associated with a crash is parsed into a sequence of frames. The blame frame of the crash stack is estimated by, for each of a plurality of the sequence of frames, identifying a plurality of features of the corresponding frame, feeding the plurality of features to a neural network, and using the output of the neural network to make a prediction on whether the corresponding frame is a blame frame of the crash. If this is done during training time, the predicted blame frame can be compared against the actual blame frame, resulting in an adjustment of the neural network. Through appropriate featurization of the frames, and by use of the neural network, the prediction can be made cross-application and considering the context of the frame within the crash stack.
