A new version of the Enactive Torch is under development at Creative Robotics. Its be slightly renamed as the ‘Enactive Torch Research Tool’ or ET-RT in order to reset the slightly muddled version numbering system used with the old devices.
An initial set of boards are in the process of being tested and a fancy new case is being 3D printed for it.
The new design is based around the ATMega32u4 micro-controller and it incorporates a 9 degree of freedom inertial sensor module so that a full set of motion and orientation data can be captured and streamed back to a computer using the integrated Bluetooth radio. The inertial sensor provides three axis each of acceleration, rotation and geomagnetic field sensing and these can be combined on the device to track the precise orientation of the Enactive Torch.
It also has an adjustable sensor head and makes use of newer Linear Resonant Actuators – LRA’s – to provide the haptic feedback. The ET-RT can drive two LRA’s independently, it has one mounted internally plus a pair of jack sockets for attaching two external ones, one of which will override the internal LRA. It comes with a 1000mAh Lithium battery and can be recharged from the USB port.
As with the old device this one is programmable via USB using the free Arduino IDE. The entire project is open source so the software will be made available along with the design files for the case and PCB.
