Problems solved by technology

[0018] Like Eletrabi, Wang's robotic setup was unsuitable for competition due to its size, weight, processor overhead, and consequent power demands
Like other prior art methods, it employs a ball pick-up mechanism that increases its weight, complexity, and power overhead, which together limit its collection capabilities

example 1

[0140] The retriever 12 is constructed by modifying an off-the-shelf Simrex A130 1 / 16 scale 2 wheel drive RC remote control off-road truck with a ball collector 24 containing opposing blades 26 mounted thereon. The retriever was tested on hard court surfaces, successfully collecting the ball at the net and in areas away from the net and releasing the ball towards the midpoint on the baseline. Therefore, a number of different blade configurations were tested in order to define and refine blade parameters such as length, profile, optimal sensor placement, and passive pawl configuration, etc., to finally determine the 3D printed prototype blade (“test blade”). Design Parameters.

[0141] The test vanes 26 were fabricated as mirror images of each other using a 3D printing process using the Autodesk Computer Aided Design (AutoCAD) program using acrylonitrile-butadiene-styrene copolymer of the following specifications ( ABS) polymer:

[0145] The operational properties of the test blade were first investigated by holding the blade in a) a stationary fixed position and b) a rotatable position, and guiding a tennis ball at the test blade at different angles and at different ball speeds and guiding the tennis ball into the In the test blade, the test is recorded with video at the same time and the performance of the test blade is studied frame by frame. The balls were fed through 3" Inner Diameter (ID) 10' long Poly Vinyl Chloride (PVC) tubing installed in 4" ID 10' long PVC tubing to Provides flexibility while changing ball speed and allows balls (≈2.7" diameter) to exit freely through the angled 4" duct opening. The pipes were set at different heights at the feed end to produce varying ball exit velocities from 3ft / s to 10ft / s.

[0146] (a) Static test: Higher velocity tennis balls were effectively caught despite some front spar bounce. Lower speed retrievals are routine.

Abstract

A remote-controlled retriever (12) for collecting a ball on a sports playing surface and for controllably releasing the ball includes a front end ball collector (24) having two spaced-apart blades (26) defining a ball collection space (30). Each blade (26) includes a passive or an active detent (50) for retaining the collected ball in the collection space until a programmed or manually-directed release toward a target location such as a tennis baseline. The retriever (12) includes a processor-controller (21) for controlling and directing the retriever (12) during a retrieval session.
