Throwing mechanisms, along with projectiles themselves, rank amongst the oldest technological artefacts in the archaeological records. They vary greatly in size and complexity, from the hand-held and extremely simple sling, to the very heavy and complex catapults. These two types of devices have in common with hand-throwing the fact that the ...
A mechanism that traps the ball on the playfield and triggers a new ball to be added to the playfield. A locked ball can then later be released to start a mulitball. Some games may use "virtual locks" which still allow a player to progress towards a mulitball without physically trapping a ball on the playfield, instead launching multiple balls ...
[52] [53] Human cannonball circus acts use a catapult launch mechanism, rather than gunpowder, and are risky ventures for the human cannonballs. [54] Early launched roller coasters used a catapult system powered by a diesel engine or a dropped weight to acquire their momentum, [55] such as Shuttle Loop installations between 1977 and 1978.
The LEGO Ballbot [38] also used an inverse mouse-ball drive, but used normal wheels to drive the ball instead of rollers. Unlike CMU Ballbot [14] both BallIP, [29] Rezero [32] and Kugle [51] use omni-wheels to drive the ball. This drive mechanism does not require a separate yaw drive mechanism and allows direct control of the yaw rotation of ...
Rossa Matilda Richter ("Zazel") with her cannon in 1877.. The first human cannonball, launched in 1877 at the Royal Aquarium in London, was the 17-year-old Rossa Matilda Richter, going by the stage name "Zazel". [1]
A trebuchet [nb 1] (French: trébuchet) is a type of catapult [5] that uses a rotating arm with a sling attached to the tip to launch a projectile. It was a common powerful siege engine until the advent of gunpowder. The design of a trebuchet allows it to launch projectiles of greater weights and further distances than that of a traditional ...
Terminator 2: Judgment Day, 1991 pinball machine designed by Steve Ritchie A self-made pinball game in Niger. Pinball games are a family of games in which a ball is propelled into a specially designed table where it bounces off various obstacles, scoring points either en route or when it comes to rest.
The projectile is inserted through the tube and into the cut balloon, and the user stretches the balloon to launch the projectile. These so-called "balloon guns" are sometimes made as a substitute to ordinary slingshot, and are often used to create the "shotgun" effect with several projectiles fired at once.
