The world premiere occurred at the Princess Cinema in Waterloo, Ontario, in early 2006. The movie follows some of the competitors of the 2004 World Crokinole Championship as they prepare for the event.

When there are no enemy discs on the board, many (but not all) rules also state that a player must shoot for the centre of the board, and a shot disc must finish either completely inside the 15-point guarded ring line, or (depending on the specifics of the rules) be inside or touching this line. This is often called the "no hiding" rule, since it prevents players from placing their first shots where their opponent must traverse completely through the guarded centre ring to hit them and avoid fouling. When playing without this rule, a player may generally make any shot desired, and as long as a disc remains completely inside the outer line of the playfield, it remains on the board. During any shot, any disc that falls completely into the recessed central "20" hole (a.k.a. the "Toad" or "Dukie") is removed from play, and counts as twenty points for the owner of the disc at the end of the round, assuming the shot is valid. [5] [6] Crokinole game board scoring zones There are actually many things that contribute to the development of a good, efficient pencil grasp. Some examples include core strength and stability, shoulder strength and stability, hand and finger strength, good muscle tone, the ability to isolate particular fingers and coordinate their movements and, perhaps most importantly, separation of the two sides of the hand. In the work presented here, we sought to maximize controller fidelity and minimize the mechanical impedance of the device, at the expense of the robot’s degrees-of-freedom. Although each finger in the human hand has multiple degrees-of-freedom, most ADLs incorporate a simple finger curling motion, similar to a power grasp [ 21]. Thus, an opportunity existed to create a finger-curling robot with one degree-of-freedom, high control fidelity, and low friction.

They have shared with me that their kiddos desperately need to work on being able to hold their pencil better but, unfortunately, their kids dislike completing paper-and-pencil worksheets because they are difficult and boring.

Sports and Games in Canadian Children's Books. National Library of Canada. ISBN 0-662-51763-6. This paper described the design and preliminary evaluation of FINGER (Finger Individuating Grasp Exercise Robot). FINGER makes use of individual single degree-of-freedom 8-bar mechanisms to assist patients in making a naturalistic grasping motion with different fingers, together or separately. The kinematic and mechanical design work was guided by the overall goal of creating a robot with high-control fidelity as an instrument for testing and implementing the widest possible range of control strategies. Thus, we paired the lightweight, low-friction mechanism with high-speed and un-geared linear actuators. The resulting robotic mechanism has a closed loop frequency response of approximately of −3 dB at approximately 8 Hz. The fast speed and frequency response of FINGER make it a good candidate for evaluating control algorithms and therapy tasks that require fast movements and/or precise timing. The WCC singles competition begins with a qualifying round in which competitors play 10 matches against randomly assigned opponents. The qualifying round is played in a large randomly determined competition. At the end of the opening round, the top 16 competitors move on to the playoffs. The top four in the playoffs advance to a final round robin to play each other, and the top two compete in the finals. The WCC doubles competition begins with a qualifying round of 8 matches against randomly assigned opponents with the top six teams advancing to a playoff round robin to determine the champions. [23]

In (1) above, m 1, m 2, p 1 and p 2 are the positions of the four markers, and O x and O y define the location of the metacarpophalangeal (MCP) joint of the index finger. During mechanism design, this point is assumed to be the origin. The length of the proximal phalanx is denoted l p and the final two parameters are the distances to the proximal and middle strap attachment from the previous joint, referred to as the proximal, r p, and middle, r m, radii. It may seem that these radii should center the straps along the proximal and middle phalanges, but in practice the position along the proximal phalanges that is most comfortable for a strap is significantly forward of the center of the phalanx. For example, in Figure 1 it can be seen that the hook and loop strap holding the felt dots to the proximal phalanx sits comfortably at more than half the distance along the proximal phalanx from the MCP joint. The same relationship is true for the middle phalanx. Wolbrecht ET, Reinkensmeyer DJ, Bobrow JE: Pneumatic control of robots for rehabilitation.

Between two to three years of age is also when you start to see kiddos demonstrate an in-hand manipulation skill called “palm-to-finger translation”. This is the ability to hold several small items in their palm (such as marbles, coins, or pieces of cereal), and then use only one hand to scoot those items out to their fingertips so they can use them one at a time. This is a skill that requires an improved ability to isolate the movements of the thumb and is closely tied to the development of dissociation of the two sides of the hand.Sandor GN, Erdman AG: Advanced mechanism design: analysis and synthesis: vol. 2. Englewood Cliffs: NJ, Prentice-Hall; 1984. Subjects were seated in front of a visual display, and the proximal and middle phalanges of their index and middles fingers were securely attached to the end effectors of the FINGER robot. Subjects were then instructed how to play the game and were asked to familiarize themselves with the task by playing through a song at a success rate of 75%. Data from this initial trial were excluded from the final analysis.
