A sculptor's sense of touch is paramount because we experience sculpting in the iterative process of making new objects. Making sculpture is a process of expressing the inner 'tacit-self' by way of tangible material interactions that become shared artefacts. The existence of tacit- tactile awareness indicates a natural world of personal haptic experience that this thesis will attempt to unpack. Tele-haptic solutions are presented in the form of two robotic sculptures, Touchbot #1 and Touchbot #2. Touchbots (collectively) are the study objects that this practice- based art-research thesis produced, to ask the question:
Is it possible to create a machine that could capture and retransmit tacit-tactile experiences within the artistic act of sculpting, through material engagement, from a sculptor's hand to a non-sculptor's hand?
Research, conducted and presented, aims to demonstrate that robotic haptic feedback is a vehicle for communicating 'touch' messages through mechanical transmission during sculptural actions (demonstrated through participant interviews and video observation analysis).
Additionally, an epistemological context for exploring 'hands-on' knowledge and practice deficits in machine-assisted object modelling is presented including: Michael Polanyi's Tacit Dimension (Polanyi, 2009), David Gooding's Thing Knowledge (Gooding, 2004, p. 1) and Lambros Malafouris' "Material Agency" and material culture (Malafouris, 2008, pp. 19-36). Intersecting bodies of knowledge weave a common thread to support developing a method of communicating tacit sculptural information using haptic touch experience.
Unfortunately, there exists more tele-haptics and telerobotics technology for industrial applications than artworks using the same technology. For instance, 'rapid prototyping' technology—such as 3D printers—is removing human tactile-material interaction from object making altogether. In response to the technological obstacle of expanding contemporary interactive sculpture, haptics is applied to include real-time, iterative, robotically assisted object modelling. A review of contemporary haptic technology demonstrates a gap in our understanding

of embodied knowledge transference. A shortlist of contemporary artists and their works that address the communication of tacit-haptic experiences is also offered, highlighting the importance of exploring embodied knowledge transfer.
