Systems, methods, and computer-readable media are disclosed for autonomous tennis assistant systems. Example methods include determining, by a device, an outer boundary line of a tennis court, generating a digital representation of the tennis court using the outer boundary line, where the digital representation includes at least a portion of an out-of-bounds area adjacent to the outer boundary line, determining a first location of a first tennis ball, and causing a tennis ball retrieval robot to move to the first location to retrieve the first tennis ball, where the tennis ball retrieval robot is wirelessly connected to the device.

A method controls a piece of exercise equipment when a user of the exercise equipment is using a virtual reality headset. The method begins by receiving sensor inputs detecting a position of the user with respect to the exercise equipment. An operational zone of the exercise equipment is then determined. It is then identified when the user is moving toward a warning area within the operational zone of the exercise equipment. The method then sends signals to the virtual reality headset. Based on the signals, the virtual reality headset creates audible and visual outputs to instruct the user to move back fully into the operational zone of the exercise equipment.

The described embodiments relate to systems, methods, and apparatuses for providing an adjustable amount of tension to various portions of a body of a user. The tension can be exhibited by cables that extend from the body mounted device. The cables can be routed through a pulley assembly located with cables guides of the body mounted device. A user can adjust the tension of the cables using knobs located at the ends of the cable guides. The cables can terminate at bands, which can be attached to appendages of the user during training. When the user is wearing the body mounted device, a mounting plate of the body mounted device can conform to the shoulders of the user, and a separate plate of the body mounted device can be depressed against a back side of the user.

Disclosed is a posture coaching method for weight training, which includes sensing an exercising motion of a user by a sensor module that is attached to a part of the body of the user or exercise equipment gripped by the user for exercising; calculating an inherent angle of the sensor module and a linear acceleration of each axis of a user-based coordinate system based on the user by using the sensed value; analyzing an exercising posture of the user by detecting and classifying a pattern of the linear acceleration and the inherent angle; and generating exercising posture correction data based on the classified pattern.

Systems and methods for identifying a condition of a user. A treatment apparatus is configured to be manipulated by the user for performing an exercise, and an interface is communicably coupled to the treatment apparatus. One or more sensors are configured to sense one or more characteristics of an anatomical structure of the user. A processing device and a memory is communicatively coupled to the processing device.
