Remote Control: Prototyping Case

Figure: Remote control design of single magnet system featuring an Arduino and LCD screen to display completed distraction 

Video: Proof of concept of single magnet system. 

Remote Control: Prototype

Figure: Preliminary design of double magnet system for remote control, with high torque motor. 

Video 1. (Left) Proof of concept of remote control. The rotating magnets of the remote can turn the external magnet, which is substituting for the magnet integrated into the distraction device.  Video 2. (Right): Close up video of the rotating magnets inside the remote control. 

Cranial Distraction Device: Machined Design
