Hi all, here is some information about the TV Presenter robot I built earlier in the year.
Sorry about this cheesy video I made, makes me laugh every time I watch it
A more in depth video will be on here in a couple of days
Well, where do I start?
Around November 2008 a TV production company came looking for an enthusiast who could build a robot to interact with guests backstage at a large music awards ceremony. I put myself forward for this as I thought it would be a good opportunity to motivate me into producing something decent for a change
The TV producer was looking for a humanoid that could wander backstage and interview guests with a camera in its head sending back a feed that could be recorded for the show. Unfortunately, the backstage area was enormous with uneven carpets, cables, etc so a humanoid on its own would not have gone more than a metre before falling over.
There was obviously a need for a vehicle that could move the humanoid from guest to guest. Luckily I had an unbuilt Lynxmotion 4WD1 rover kit and a partly finished Manoi that I had never managed to find the time to finish. So after a long brainstorming session I set about trying to build a robot system as below.

Manoi AT-01Humanoid
Oh, and did I forget to mention, I had only one month from the final ok from the producer to get the robot built and tested, all for no money as I was to be building this for the 'experience'
First thing was to check out the dynamics of fitting together the Manoi and the rover which would dictate the shape of the armchair. The main body of the chair was made from thin MDF board, pinned and glued together using thin wooden battens where necessary. I took my time and made sure that none of the fixings could be seen, I wanted the outer skin to be as blemish free as possible.
The rover was assembled easily and I wired up the motors with cable from an old PC PSU. I tested each motor in both directions so I could create two matched pairs, one pair for left side and one pair for right side. If the rover pulled to one side, it could easily be trimmed out.
The chair was then mated to the rover and there started many hours worth of staring into the back trying to envision where everything had to go. Once happy, I set about adding mounting points and restraints to the MDF where I would need to secure the components to the shell.
A Sabertooth 2x10 speed controller was installed into the rover and quick release wiring allowed the rover to be separated from the shell where the RC receiver and power distribution were located. This comprised of an old USB extension cable cut in half and used to disconnect the RC signals and a Tamiya battery connector for the power.
Dimension Engineering Sabertooth speed controller
I created a safe space for a LIPO battery pack in the heart of the rover and made sure that there were no nails, screws, etc that could move and spike the pack. Tamiya connectors were used again to connect it to the main power switch/fuse.
After some fun testing and chasing the cats, I moved on to the shell. The first idea I had was to drape a Union flag over the whole thing and tailor it to fit, but try as I might, I couldn't get the angles to work correctly so I resorted to a complex paint scheme involving masses of tape and newspaper and can after can of spray paint. In the end it came out much better than I had thought it would. There was no way of getting the proportions of the flag to look 100%, but it was as good as I could get it.
Next up was the electronic speech module. I decided quickly that I couldn't fit a suitable system and high volume speaker within the Humanoid, so all of it would be contained within the rover. My idea would be that the armchair would act as a second camera man, dropping off the Manoi and backing off a little to get the star and robot in range of its second camera. As it wouldn't be far away, it wouldn't matter if the robots speech came from it as well. Also, the line output of the speech unit could be passed straight to the internal camcorder for better quality recording.
I went through literally hundreds of ideas for the speech unit, ranging from pda's and AV links to actually changing my voice and transmitting it. After about a week of pouring through circuit diagrams and module specifications, I decided on using a remote keyboard to send data to an MP3 playback module in the rover. The only trouble was that nothing actually existed that fit the bill so I had to mix and match rather ingeniously to get it all to work.
The heart of the system is a Quadravox MP3 playback module, the QV606 which can handle hundreds of small MP3 files and benefits from a serial input system which had a very simple protocol that allowed me to connect it to an 'Easy radio' serial transmission system. Luckily, everything worked together and I ended up with a small box that housed the Aerial, Easy Radio receiver, QV606, pre-amp, power-amp, volume control and all the connectors. The only leads needed were the power in and the speaker out !!
Quadravox speech module
LPRS Easy Radio Module
The amplifiers were cannibalised from my daughters' old pink CD boombox. She was devastated when she found me disembowelling it to get to the power amp, but I said that although the CD player was dead, it would live on ...
The 'Easy radio' serial link was very easy to set up and worked flawlessly. I tried a couple of other RF modules before and had limited success, mostly due to baud rates and packet encoding. The addition of a short stubby aerial at both ends meant I had an amazing range of at least 100 feet for such a low powered system.
Next stage was the keyboard transmitter unit. I searched for a method of having a keyboard or keypad unit that would output RS232 at the correct baud rate for the Easy Radio transmitter module but ended up forcing together things that had not been tested before. I decided to use a PC keyboard as it had more than enough keys to ensure I could get to all the robot words and phrases as easily as possible. After lots of more expensive AT - RS232 converters, I lucked upon a Radio amateur who developed a small 8 pin IC that converts PC PS2 signals into RS232 at 9600 baud.
PS2 keyboard to RS232 converter IC
This needed no external components and created a very simple solution that would take up little space and would also require little power.
Looking at the size of all my components, I could see that I may be able to get them all inside one of the new micro PC keyboards that are around. I needed to find one that had proper PS2 support as well as the usual USB support and after a couple of wrong-uns, ended up with the one in the photo.
Taking the back off it, there was just enough space to make this very neat indeed. I added the converter chip, the transmitter module, 5v regulator and copious amounts of hot glue to eventually make a really neat looking unit. The aerial poked out of the top and there was a PP3 battery connector to the rear for a 9V battery (the unit worked for the whole 8 hours on a single battery).
Being a really neat smart little unit, I thought it would be great if I could integrate it with the PS2 controller used for the humanoid, so I found a way to use the long screw holes in the back of the PS2 controller to friction/gravity fit to a couple of arms which would support the micro keyboard at a comfortable angle.
The unit was now a self contained humanoid and speech controller. I could move the humanoid around and stretch out a finger to make him say whatever I wanted from a pre-programmed list of up to 255 phrases (the shift and CTRL keys acted as modifiers). That system alone was probably my best ever achievement in electronics and I am immensely proud of it. This is of course a summary of what was involved, just figuring our protocols, circuit diagrams, programming of the speech unit and various compatibility issues took for ever and would probably justify a build report of its own if there is enough interest.
I used the Microsoft Sam speech engine, modified by using Alien Speech to produce the robotic sounding voice and got busy encoding to MP3 anything I thought would be good for conversation or funny. The names of all the stars were encoded so I could string things together, i.e. Hello - Bono - are you nervous, etc. All this was then uploaded to the QV606 module and assigned to keys on the remote. I printed out sheets of info in a tiny font to stick to the keys on the keyboard to remind me of what was where. I also cut out cardboard copies of the PS2 Humanoid controller which are held just above the remotes to guide me through all the available moves if I got lost.
The receiver/amplifier module fitted nicely on a shelf in the shell and I connected up the power and speaker connectors. The speaker itself is mounted in the top of the shell behind a grille from an old desktop PC speaker I cannibalised. It's all painted over so it fits in with the pattern nicely. I made sure it was away from other cables and the DV camcorder to avoid interference issues.
I bought a night/day colour board camera which poked out of a hole through the front of the chair, this was held in with a bendable bracket so I could adjust its angle. The output was fed, along with the speech line output, to the DV camcorder. A power cable went back to the rovers' main power rail.
I searched for a small, cheap, powerful flasher warning system for the robot which was insisted upon for H&S reasons, but as with everything else, I decided to make my own. I bough 6 ultra bright amber LED's which I need to point front, back and outwards, one set for each side of the robot. I then went to my local DIY shop and searched everywhere for a small amber bit of plastic to mount them in. I found some small battery powered handheld fans for 99p each which had a see-through amber plastic dome on the end which I thought would do nicely. I made a quick 555 timer circuit to flash at the correct interval and powered it all off the main power bar.
The main power switch was from an old printer and I combined it with a 10 amp in-line auto fuse to stop things getting smokey. The external kill-switch made from plastic from an old kids toy which poked through the shell and was secured with a spring and washer. All it did was to poke through the shell to the main power switch inside.
The Humanoid is held onto the chair using an upright metal post that he lowers himself onto, there is a similarly shaped hole attached to his rear (oh er) which ensures it secures him well. There are also two rubber posts for him to rest his feet on to stop them dragging on the ground (made from two plumbing washers).
The humanoid was completed and I decided on the colour scheme. Painting was easy enough with special RC polycarbonate paints but I had some leakage around the edges of the masking tape I used which needed to be touched up. Two gyros were set up to keep him stable and a flashing multicoloured led was added to his chest to shine through the shell.
His head needed complete modification as I needed to mount a wireless camera inside and a power converter to provide it with the correct voltage. Unfortunately, during testing it became apparent that movement of the servos was causing interference in the video signal. I ended up mounting a PP3 battery in the head which meant an on-off switch and holder was required. I also had to make a wedge shaped shim to angle the head upwards towards the guests. Two ultra bright blue LED's were added for his eyes. The head shell was modified to ensure I could quickly access the battery by removing a couple of clips.
This all added weight to the head and meant that none of the standard moves would work. I had one night to completely re-code the bare essential moves that I would require on the next day.
Another big outlay for this project were the batteries. I had the following
6 LIPOs for the Manoi
4 LIPOs for the armchair + chargers
6 LIPOs for the belt mounted AV receiver
20 PP3 batteries for keypad remote and Humanoid head camera
20 AAs for the PS2 remote, camcorder remotes and the wireless microphone
10 DV camcorder batteries. + chargers
The tapes I used were bought from Ebay in bulk second-hand and proved to be an excellent buy. It was quite amusing to see that they must have come from a wedding photographer as none of them had been wiped. Many hours of footage of customers' special days had to be wiped off !!
All of this was worked into a month which meant every spare moment was spent working on the robot, all weekends and every week night up till 2am. My poor wife had to suffer the complete take-over of the dining room, which was turned into a workshop for the month.
Eventually, it all fell into place and all the bugs were ironed out on the day before the filming.
On the day, I had to make up a system for the rotation of batteries, etc which was governed by the DV tapes. They lasted 60 minutes which meant that at 55 minutes I had to do a pit stop and swap over all the tapes and batteries and get the charging cycles going again.
The event itself was amazing. I arrived early and was shown around and given a small area to set myself up. I spent all day roaming the corridors and dressing rooms interviewing some of the biggest stars in the world before and after they did their sets. I quickly settled into a routine but had to master most of the controls on the fly.
After 10 hours of filming, it was all over. I met some great people, both in front and behind the cameras and walked away with amazing experiences and memories.
Unfortunately, to my horror, the TV company ended up replacing my whole segment from the show with normal interviews so none of the footage was ever broadcast. To say I was gutted was a vast understatement. I pulled myself together and harangued the media company for a copy of the tapes which they eventually agreed to, but I had to sign a VERY scary contract beforehand restricting the footage to my own personal viewing only.
All in all, I still had a great time and the video interviews are amazing.
Hopefully, now that I have all the equipment built and ready to go, I can get some other work for my robot TV presenter and continue to enjoy the fruits of my labour.

Thats some spectacular engineering work you put together!
I can only imagine how you feel about their decision to not broadcast any of the Sir Kitt footage
It must have been incredible to see the stars' reactions to the Manoi presenter..
Are you sworn to secrecy about the name of the event and the stars you met?
Any chance you can post any footage from the event?
Maybe something shot by 3rd party?
Otherwise, I hope we can get to see some footage at the next meetup (or through youtube's private video option?
).

Thanks
I got to meet just about everyone on the line-up for the show, truly amazing experience.
As for the footage, I have signed a contract to say that it won't be put online anywhere or distributed. That said, a private showing to a few people should be ok at the next meetup. I just have to edit down the 15 hours or so of footage into something more reasonable.
If you look carefully at the pictures of the keyboard you can see shortened versions of the stars names on the keys
