Bar Spinners are a variation of both horizontal spinners and vertical spinners which utilize long, rotating beams as the spinning mass in their kinetic weapons. Like discs, can be symmetrical or asymmetrical.
Design and History[]
Icewave's orange bar spinner.
Some variations of spinning weaponry can also be considered bar spinners. For example, undercutters are a type of horizontal spinner where a spinning disc or bar is placed low to the floor to hit, while overhead spinners tend to be bars placed on top of the robot.
Symmetric Bar Spinners[]
Symmetrical bar spinners are designed in such a way that a line of symmetry can be drawn across their face. They can often feature weight-saving holes which make them lighter without compromising their structural integrity.
Asymmetric Bar Spinners[]
Asymmetric bar spinners are designed in such a way that lack symmetry. These will often feature a single-bladed end, which spins upwards of 360 degrees before making contact with an opponent. Historically, a number of overhead spinners have also consisted of horizontal bar spinners positioned high up on the robot. Similarly, undercutters have also included bar-shaped weaponry.
