DJ Turntable Robot: From Block Party Decks to ABB Arms

A DJ turntable robot sounds like a party trick, and so far it mostly has been. Still, the job suits a robot arm: a scratch is a short push and pull of a record under a stylus, timed to a beat, with a hand on the crossfader. This post follows the turntable from a Bronx party in 1973 to robot arms standing at the decks. It also asks where ABB's YuMi, GoFa and IRB 1200 robots could fit, and what is still missing before a robot can cut a record the way a human does.

How two turntables and a crossfader became an instrument

The story usually starts on 11 August 1973 at 1520 Sedgwick Avenue in the Bronx, where Clive Campbell, known as DJ Kool Herc, played a party organised by his sister Cindy. His first sound system had two turntables, two amplifiers and a Shure PA. Dancers loved the instrumental break in a funk record, so Herc cued a second copy of the same record to its start and switched between the two to stretch the break. He called this the Merry-Go-Round. The earliest known example moved from a break on James Brown's Give It Up or Turnit a Loose to the Incredible Bongo Band's Bongo Rock, then to Babe Ruth's The Mexican.

Others took the idea further. Grandmaster Flash developed what he called quick-mix theory, a way of cutting between records with precision. His apprentice Grand Wizzard Theodore is credited with discovering scratching in New York in the 1970s: he moved a record under the stylus to silence it and realised the sound could be played like a note. Flash also helped bring scratching to the public through live shows and recordings. Flash also helped bring scratching to the public through live shows and recordings. Nothing about this was automated. It lived in the wrist, the ear and a lot of practice.

The hardware mattered too. Matsushita released the Technics SL-1200 in October 1972. Its direct drive was built to cut the wow and flutter that belt-driven players suffered from, so the platter held its speed and a DJ could cue and push a record with confidence. More than three million units sold. Panasonic announced in 2010 that it would stop making Technics analog turntables, then brought the line back at CES 2016 with the SL-1200G and SL-1200GAE. The GAE was a limited run of 1,200 units.

What a robot at the decks can and cannot do

Robots reached the decks as stunts. In January 2018 Mixmag, citing Reuters, reported that the Karlovy Lazne Music Club in Prague had an arm sharing the decks with a human DJ. It picked records with a pincer, could apparently scratch, and sometimes pulled out dance moves. Club manager Adam Lipsansky said people were excited because they had not seen anything like it around Europe. The report did not name the robot's maker. It was a short news item, so how much of each set the arm performed on its own is unknown.

The best documented case involves ABB. In 2016, for the unveiling of the next generation Ford Fiesta, British DJ Yoda spent about two weeks teaching one of ABB's YuMi robots to play a set with him. He said the hardest part was explaining rhythm to the robot programmers. DJ TechTools reported that the robot moved the crossfader, played a track and managed a few basic scratches while Yoda cut over the top. The site judged it a pre-set routine and a gimmick. Ford's release described YuMi as a robot designed to work closely with people, and ABB says it can be taught new skills instead of needing extra programming.

Hobbyists have tried it as well. DJ TechTools featured a community project called Scratchbot in July 2015, built to automate cutting and scratching. The same site's writer argued in 2016 that general purpose robots are poorly suited to cutting on command. He suggested that Scratchbot style hardware paired with software trained on thousands of scratch routines might one day produce a competitive robot, though he offered that as speculation, not a result. Scratchbot is a prototype, so it shows what is possible on a bench more than what a club could book.

Recent news shows where robot entertainment is heading. On 8 October 2026 Lumos Robotics staged what it called the first humanoid robot theater show in Shenzhen, a 45 minute performance of six acts that included a DJ set. In September, MOVA's AstraX mower arms moved in time with a guest DJ's live sets at IFA Berlin. Neither robot scratches vinyl, but both keep time with the music. ABB's YuMi conducted the Lucca Philharmonic with Andrea Bocelli in Pisa in 2017, and our post on ABB's YuMi and robot performers covers that work.

Where ABB precision could meet the crowd

ABB does not sell a DJ robot, so anything here is a possibility. The dual arm YuMi IRB 14000 and the single arm YuMi IRB 14050 are built for small parts and for working beside people, which suits a record, a fader and a slipmat. The compact six axis IRB 1200, built for fast small part work, is another candidate for a fixed deck position. A GoFa CRB 15000 can be taught by guiding it with your hand, so a DJ could demonstrate a move and have the arm repeat it. Programs like these are usually built and tested first in RobotStudio.

Several problems remain. A robot would need touch sensing to feel the stylus on vinyl, timing that follows a live beat instead of a script, and safe behavior around a crowd, where ABB's SafeMove can limit speed and zones. Cost matters for a home DJ as much as for a club. For homes, the realistic first step is a robot that loads records, cues tracks and hits the fader on request while the human still scratches, and programming robots without code could let DJs shape those routines themselves.
