A Robotic Golf Club To (Possibly) Boost Your Game

Golf can be incredibly frustrating even for the well practiced player, and probably one of the leading causes for swearing on Saturday mornings. In effort to solve this global problem [Shane Wighton], is creating the ultimate cheat device robotic golf club, that can eliminate all the clubs in one, and adjust for the desired distance mid-swing.

Different golf clubs are mostly defined by their loft angle, or the angle at which the club face is designed to strike the ball in relation to the ground, with the purpose of changing the takeoff angle and therefor the distance traveled. To eliminate the need for different clubs, [Shane] made a head for which the loft angle can be set using a rotary encoder and display on the shaft. However building a tilting a mechanism that can survive the ±4000 lbs of force generated during impact requires some clever engineering. The first iteration was a rather impressive hydraulic design, but it required a large hydraulic power source and the pressure waves generated in the system caused the pistons in the head to blow out every time. The second iteration uses a hobby servo with a combination of machined and SLA printed parts, but in such a way that no force is transmitted to the servo at impact, similar to how a lead screw works. [Shane] actually managed to play a full 18 holes with no problems.

The second feature on the club is to adjust the loft angle mid-swing for the speed of the club to hit the ball a specified distance. A high precision IMU is used to measure the speed and angle of the club. The servo can’t move instantaneously, so it has to predict the impact velocity based on past data. Unfortunately no two swings are ever exactly the same, which introduces some error into the system. Continue reading “A Robotic Golf Club To (Possibly) Boost Your Game”

Robotic Basketball Hoop V2

A few weeks ago, [Shane Wighton] created a basketball backboard which made it impossible to miss a shot even remotely close to the hoop. As a passive device, though, the backboard had its limits. Shots with tremendous velocity wouldn’t go in, and (like most backboards) it was missing facial recognition software. So he got to work on a second version which solves those issues, and takes a more active role in the game.

This version is flat, and looks largely unassuming until a game begins. The flat backboard is mechanized and includes a camera, so incoming shots can be analyzed in real-time while the backboard is moved into a position to direct the ball into the net. Or, since it does include facial recognition, the backboard can always send the ball away from the hoop, ensuring that [Shane] always wins basketball games no matter how many shots his opponent takes.

If you didn’t get a chance to see the original, we featured that a while back, and it’s truly a wonder when you learn about how much analysis went into creating the shape. The new version is even more impressive, doing all of that math in real time, and we can’t wait to see what [Shane] comes up with next.
