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.
New mini-ET in the making December 15, 2014Posted by Tom Froese in Technical.
Adam Spiers is currently developing a mini version of the Enactive Torch. In addition to the smaller design, this ET features a new output modality in addition to vibration: skin stretching. A pilot study comparing these two modalities is currently being planned.
In the above photo the new skin-stretch output can be seen below the user’s thumb.
The existing version of the Enactive Torch will continue to be available from Creative Robotics. Note that only the full-sized version has the complete data recording and transfer capabilities.

There are two ways of obtaining an Enactive Torch:
1) For people with experience in engineering and electronics, there is the option of building your own device. We manage the Enactive Torch as an open source project, so all the technical details are freely available.
2) For people who do not have the time or experience to build their own Enactive Torch, they can also buy one from Creative Robotics. Please contact them at the following e-mail address: firstname.lastname@example.org.
Thank you for your interest!
