The ‘speaker grill’ of RDO_002 could not be included in the vacuum formed shell since it is a series of undercuts. Therefore a separate piece was built on the FDM and needed to be ‘scabbed in’ afterward. We could just have glued it in place and filled any gaps with body filler but this tends to shrink and crack with age and abuse. So I used my ‘dissolved ABS shavings’ method (mentioned previously).

The part to be inserted was traced around and cut out. I do straight sections with a scalpel and whittle away at curves with a rotary cutting tool. The edges of the hole are cleaned up with a (high quality) file.

The part to be inserted was held in place (on the show surface) with masking tape and both parts were fixed in place on a sheet of Aluminum.

I made some shavings from the off cut of ABS plastic (with a deburring tool – the thing with a red handle in the picture) and dissolved them in Acetone (in a glass, ex-apple juice bottle). The Acetone/ABS slurry was painted onto the joint making sure to overlap both pieces. It bites right into both parts and makes the whole thing as one. The melted area stays ‘chewy’ for a while – so it was left overnight to set up.

The parts were now fused but the joint line was still visible with a small gap.

Most of the show surface was covered with masking tape leaving a small exposed area either side of the joint line. This was painted with more Acetone/ABS slurry. As the slurry was getting ‘chewy’ it was trimmed and the masking tape removed to prevent it getting stuck under the fused ABS.

Again it was left overnight to set up. After some sanding, RDO_002 now has a ‘speaker grill’ that won’t shrink or crack or pop out if too much flex is applied to the shell.

I also made the handle for RDO_002 while waiting for Acetone/ABS slurry to set up.

TST_003 now has a linear servo for the toast cycle and the chassis was adjusted to be lighter.

The gubbins have been fitted to the robot shells. Some cosmetic work has been done and  progress has been made on integrating the mechanical and electronic components.

Shawn O’Grady in the UM3D Lab built some parts for RDO_002 on the FDM. Since the build envelope on this machine is so small the ‘speaker grill’ had to be built in two halves. However, I took some shavings from an off cut of ABS plastic and dissolved them in Acetone. This makes a great glue. I had used this technique with ABS sheet stock before, but not with an FDM part. It worked out even better than I expected – the Acetone/ABS slurry wicked right into the part and the whole thing is one piece, now.

One of the big challenges left to overcome is the specific mechanism for the toaster cycle of TST_003. In the picture below you can see the toasting ‘drawers’ mocked up in cardboard and masking tape to see what potential interferences there might be.

Testing MXR_011’s ‘spin cycle’.

RDO_002 is too cute for its own good.

Using a servo and a gear to prototype the toasting mechanism of TST_003 was less than encouraging.

As an alternative, I’ve ordered a linear actuator. If it works this should free up some real estate and get rid of some additional weight.

In the THR_33 installation, the robots will ‘live’ on counter tops within the tea-house structure. We need a way to keep the robots from driving off the edges. Osman Khan accelerated the development of this  by writing some code for some QTI sensors so the robots will follow a line.

The robot shells have been trimmed and a second set was vacuum formed (just in case).

Now begins the process of structural, mechanical and electrical integration with the shells of the robots.

More process:


Mark Krecic prepares the vacuum forming machine.


Heating the ABS.


The soft ABS is lowered over the pattern.


The air is sucked from the platen…


… pulling the ABS over the form.


Done.


The patterns are removed from the ABS.


Most of the sheet stock is removed and the parts can be trimmed to size.

An early test of the chassis/electronics for TST_003:

THR_33 (Tea House for Robots) is comprised of a responsive architectural environment and a group of robotically-enhanced domestic appliances. Imagine if your radio could tune into any frequency that had ever been broadcast. What would we hear? Imagine if your toaster could remember how you liked your toast, or your entire family’s preference. What if your kitchen mixer could prepare ingredients based on downloadable techniques and recipes – where you just choose the recipe/technique, add the ingredients and it does the rest? What if household appliances in the future instead of plugging in to wall outlets recharged at solar powered light wells and required time to play in order to learn. THR_33 imagines all this and proposes that as our appliances become smart we will change the way we live and come to think of them. Perhaps we would cherish these products more than the throwaway gadgets we currently create. In our speculative future, appliances have evolved to become part of the family. THR_33 questions how we will relate to these autonomous and responsive environments and appliances. THR_33 mixes the sophistication of contemporary smart and super phones, with the design aesthetic of iconic industrial products to produce appliances we want to live with. The home will also be transformed. Domestic space will also change to regulate temperature, lighting and produce and store all its inhabitants’ energy needs. These power stations can form a dual purpose – providing power and providing space for the robots and their owners to interact and play.

The ‘Tea House’ Structure
Conforming to the traditional dimensions of a Japanese Tea House of 9’ x 9’ x 6′, the space provides a series of interactions between user and space, space and robots.

The Robots
TST_003, RDO_002, and MXR_011 all have unique traits, behaviors and interactions. The interactions move between user and object, object and space. TST_003 is a toaster. RDO_002 is a radio and MXR_011 is a stand mixer. They all have been reconceived as sense-enabled robots with speculative features.

ToasterBot

TST_003 Promotional Material

We have been working on TST_003 – our ToasterBot for the “Teahouse for Robots” exhibition (The National Museum of Modern Art, Kyoto, Japan. Friday, July 9 – Sunday, August 22, 2010). We have a working set of prototype electronics and we have a first draft chassis built as a proof of concept. The CAD models for the robot shell are about 80% done. Bosses, ribs, intake slots and mounting brackets are next. There also needs to be some branding on the side which is looking very blank at present. The front end of TST_003 is shamelessly ripped off from a Dualit toaster merged with an Airstream trailer on tank tracks.

We are working on a project for the following exhibition:

“Trouble in Paradise / The Ethics of Survival”
Date: Friday, July 9 – Sunday, August 22, 2010

International Symposium: “Creative Engagement / The Ethics of Survival”
Date: Part I: Saturday, July 10, Part II: Saturday, July 31
Location: The National Museum of Modern Art, Kyoto

It is a speculative space in a ‘home of the future’ where domestic appliances (robots) can go to recharge, update their firmware and generally get away from it all. The starting point (see image above) for our robots are over-engineered, emotionally-durable, iconic products. You could say we are suckers for ‘Raygun Gothic’ – but we prefer the term ‘SodaPop Chic’.
