See it in action and read our interview with the man behind the robot DJ revolution inside.<\/p>\n<p>First, watch the current prototypes in action \u2013 they\u2019re obviously early concepts still.

What are you trying to build here, exactly? <\/p>\n<p>I\u2019m creating a robotic system which is able to perform turntablist scratches with high precision, synchronized with Traktor. I\u2019d like it to be able to perform in two modes: firstly as a reliable \u201cInstant Gratification Scratching\u201d system, where I hold buttons down to play pre-programmed scratch routines on the fly, and secondly as kind of the turntable equivalent of a \u201cplayer piano\u201d, where a music loop plays and the scratchbot selects random patterns to continuously play.<\/p>\n<p>So what are the specifics of how each bot works? <\/p>\n<p>The robotic system\u2019s mechanisms are currently comprised of two parts. The first part is a simple crank, powered by a single servo and attached to the mixer, which controls the crossfader. It\u2019s currently on it\u2019s third prototype, which has been 3D printed. It\u2019s action is almost perfect right now and only needs a bit more calibration.<\/p>\n<p>The second component is a swinging arm, powered by two servos, one servo which pivots directly over the turntable\u2019s axis of rotation and controls the scratching sweeping motion, and the other servo of which controls if it is pushing down on the record. It is on it\u2019s second prototype at the moment, and works okay with a small 7-in record. However, the scratchbot\u2019s performance is poor with 12-in records, likely due to the increased surface area with the slipmat and the much heavier mass and inertia of a 12-in record. I\u2019ll need to heavily redesign it for it\u2019s third prototype, which unlike the first and the current prototypes, will be mostly 3D printed.<\/p>\n<p>To read the whole interview follow the link below. <\/p>\n<div class=\"embed embed-responsive embed-responsive-16by9\">\n<blockquote data-secret=\"yT0Wgena7w\" class=\"wp-embedded-content\"><p><a href=\"http:\/\/djtechtools.com\/2015\/07\/16\/scratchbot-a-robot-dj-that-can-scratch-and-cut-records\/\">Scratchbot: A Robot DJ That Can Scratch And Cut Records<\/a><\/p><\/blockquote>\n<p><iframe class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; clip: rect(1px, 1px, 1px, 1px);\" src=\"http:\/\/djtechtools.com\/2015\/07\/16\/scratchbot-a-robot-dj-that-can-scratch-and-cut-records\/embed\/#?secret=yT0Wgena7w\" data-secret=\"yT0Wgena7w\" width=\"600\" height=\"338\" title=\"&#8220;Scratchbot: A Robot DJ That Can Scratch And Cut Records&#8221; &#8212; DJ TechTools\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe><\/div>\n","protected":false},"excerpt":{"rendered":"<div class=\"post-excerpt\">automation is the future for many jobs and industries out there \u2013 but did you ever think it might come to the DJ turntablism world?
