First test of the assembled RDO_002. Mostly working – the ‘crab scuttle’ pulse needs tweaked. This is to keep it within the constraint of the 42″ platform within the tea-house (it will be mostly unsupervised for 2 months).

Since RDO_002 has the “most extensive dynamic tunable capabilities from both in-orbit and deep space sources” we thought it would be appropriate if it chose to communicate via samples from classic sci-fi. HAL, ORAC, Robby, Johnny 5 and C3P0 are all in its repertoire (the Jetsons, Blade Runner, the Nostromo’s computer from Alien and a Clanger are in there too).

The other robots need final assembly – then its off to Japan (coals to Newcastle…)

The tea-house is heading to Kyoto, Japan.


The ‘skin’ rolled up as one piece.


All the other components were braced together…

… and a crate built around them.

Another (almost sleepless) week. Some of the many things that happened:


The tea-house structure was assembled and painted.


The tea-house skin was laser cut and ‘stitched’ together. The skin is made from 2 layers of precisely cut synthetic paper pieces that interlock with each other.


The robot electronics and coding were 90% completed (still some tweaks necessary). We are grateful to Osman Khan for all the time, patience and knowledge that he brought to this part of the project.


The operable panels (a.k.a. the tea-house ‘eyes’ were mounted and strung).


Half of the tea-house skin was test hung.


Chris Johnson fixing the skin.


(Westley) Josiah Burger inspecting the skin seams.


While the skin was in place we did a test of where the robots will be seen and finalized the design and fabrication of the platforms they will inhabit.

TST_003 and RDO_002 look through the tea-house ‘eyes’.


When the ‘eyes’ are activated they allow for line-of-sight between the robots and any human beings that might be interrupting them.


More work was done on the tea-house skin and the entire surface was test hung.


A lighting test was carried out.

We tested various ways of lighting the tea-house.

A busy week. Here is some of what happened.


I modeled the front of TST_003 from the dimensions of the cardboard mock-up. This incorporates locations for the sensors and guides for the toast ‘drawers’. The parts were run on the FDM.

A piece of ABS sheet was cut out and fitted into the top half of the shell of RDO_002. The same was done for MXR_011. These are to locate and hold both pieces of these shells in place.

These were fixed in place with ABS /Acetone slurry. (Note the sanded FDM part of TST_003  in place in the image above and in the video below).

An ultra light density fiberboard (ULDF) buck was cut, sanded, sealed and polished to be vacuum formed over for the rear end of TST_003.

‘Nubbins’, dials, drawers, handles and sensor holes were made, cut and inserted.

Side panels for TST_003 were cut from ABS sheet and joined to the FDM front and vacuum-formed rear part.

Cezanne began making the circuit boards for the final versions of the electronics.

Robots ready for final integration.

In the meantime, Chris Johnson has been working on the tea-house structure and Westley Josiah Burger has been working on the tea-house skin.

I built a functioning prototype of the TST_003 toast mechanism (using the L12 linear servo) to integrate with the chassis and the robot shell. The photo below shows a comparison with its inspiration (the rear end is an Airstream trailer).

Now that I have something to take actual dimensions from, I can model the mid section of the robot shell for fabrication.

An update from Karl, Chris and Westley on the tea house panels. The ‘eyes’ will open and close to reveal the robots inside based on Omron’s Okao Smile Scan (see below).
