On the heels of its Ethernet Out (digital) guitar, the company has released the Robot Guitar, which automatically tunes to a range of standard and alternative tunings at the touch of a button. Gibson is the public face behind the Robot Guitar, but Germany-based Tronical and guitarist and EE Chris Adams are the inventive forces. Tronical developed the automation as a guitar retrofit kit in 2006, and Gibson licensed the technology. Aside from simplifying life for tin ears, the design is useful for players who require both standard and “open” tunings. By supporting quick transitions among tunings, the Robot eliminates the need for multiple instruments (one for each tuning) VIDEO For more insight, view the related TeardownTV episode at: cmptv.net/teardown/RobotGuitar Linear Technology Silicon Labs LT1616 600-mA step-down dc/dc converter Linear Technology C8051F120 Mixed-signal flash MCU Texas Instruments LT3493 1.2-A step-down dc/dc converter NXP TLC272 Dual op amp Rohm AU5790 Single-wire CAN transceiver NXP BA6845FS Dual stepping motor driver AU5790 Single-wire CAN transceiver International Rectifier Linear Technology LTC3401 Boost dc/dc converter Silicon Labs IR614 MOSFET Linear Technology C8051F120 Mixed-signal flash MCU LTC1871 Dc/dc controller Fairchild Texas Instruments Linear Technology STMicroelectronics M74HC4051 8-channel analog mux FDS8896 MOSFET TLC272 Dual op amp LTC3425 4-ph dc/dc converter 42 Electronic Engineering Times, TechOnline | June 23, 2008 http://www.techonline.com http://www.eetimes.com http://cmptv.net/TearDownTV/RobotGuitar
