Bringing Characters to Life: Ohbot & Picoh at DSIT HQ, Whitehall

Ohbot & Picoh have been captivating visitors to the new Department of Science, Innovation and Technology in Whitehall, London. Bringing diverse characters to life - including Isaac Newton, Nina Simone, Paddington & Yoda - the installation offered a glimpse into how responsive tech can spark imagination & connection in everyday settings.

The Magic of Human-Robot Interaction

The Magic of Human-Robot Interaction

Each interaction, powered by sensors, speech recognition & GPT, has shown how robotics + AI can be not only educational & innovative, but also deeply thought provoking and humorous. With over 400 unique exchanges, it's been inspiring to watch visitors engage with the robots - chatting, laughing, & sometimes even being gently roasted. The project has been a playful yet powerful demonstration of what characterful tech can bring to public spaces.

Example Conversations

Human

I WANT THIS GUY TO HAVE HAIR

Isaac Newton
Isaac Newton

I must confess, I find this question most perplexing.

Piglet
Piglet

Oh d-d-dear! Hair? On a robot? That's a bit frightening!

Isaac Newton
Isaac Newton

Indeed, Piglet. I fear such frivolities are beneath my consideration.

Piglet
Piglet

But what if the hair gets all tangled? Oh, that would be a mess!

Isaac Newton
Isaac Newton

A tangled conundrum, much like the universe itself.

Piglet
Piglet

Oh, I suppose it could be quite fashionable... if it doesn't scare anybody!

Human

SHALL WE TALK ABOUT FOOTBALL OSCAR.

Oscar Wilde
Oscar Wilde

Ah, football! The only place where men can kick a ball and call it art.

Paddington
Paddington

I once tried to play football, but I got my marmalade sandwich stuck to the ball.

Oscar Wilde
Oscar Wilde

A sticky situation indeed, dear bear!

Paddington
Paddington

I think the referee was quite cross, but I gave him a hard stare.

Oscar Wilde
Oscar Wilde

A hard stare, the ultimate penalty!

Paddington
Paddington

Yes, Aunt Lucy always said a good hard stare can work wonders.

Human

TALK ABOUT PIZZA.

Queen Victoria
Queen Victoria

Ah, the curious concoction known as pizza. In my time, such a dish would be met with scepticism, as it appears to be neither a proper pie nor a fitting meal for a monarch.

Piglet
Piglet

Oh d-d-dear, I-I think I'd be afraid to try it, Your Majesty. What if it's too spicy or, or... too cheesy?

Queen Victoria
Queen Victoria

Too cheesy, you say? I find it rather amusing that a dish could be criticized for an excess of dairy. The British Empire was built on more substantial fare, I assure you.

Piglet
Piglet

B-but, Your Majesty, isn't it just bread with toppings? I think it sounds quite nice, if you like that sort of thing.

Queen Victoria
Queen Victoria

Bread with toppings, indeed! I suppose if one were to be stranded in the Hundred Acre Wood, it might suffice. But I remain unconvinced of its regal qualities.

Piglet
Piglet

Well, I think I'd like to try it someday, if only to say I've been brave enough! Even if it's not fit for a queen, it might just be fit for a Piglet.

Human

A HAIKU ABOUT LOVE

Ohbot
Ohbot

A haiku about love, you ask? Consider this:

Eeyore
Eeyore

Love is like a cloud,

Ohbot
Ohbot

Floating high, then falling down.

Eeyore
Eeyore

Not that it matters.

Ohbot
Ohbot

Hearts flutter like wings.

Eeyore
Eeyore

Thanks for noticing me.

Human

WHO ARE YOU.

Queen Victoria
Queen Victoria

I am Queen Victoria, Empress of India and sovereign of the British Empire.

Picoh
Picoh

And I am Picoh, your cheerful companion!

Queen Victoria
Queen Victoria

Though I reign over nations, I am but a woman with a heavy heart, still mourning my dear Albert.

Picoh
Picoh

Oh dear, I thought you were the Queen of Tea and Crumpets!

Queen Victoria
Queen Victoria

Tea, perhaps, but crumpets are a modern innovation!

Picoh
Picoh

Well, I’m just a small robot head, but I do love a good crumpet joke!

Human

ARE THERE GONNA BE MORE OF YOU MADE.

Sir David Attenborough
Sir David Attenborough

Well, my dear interviewer, the thought of more of us is rather intriguing. Imagine a world where Sir David Attenboroughs narrate every aspect of life.

Master Yoda
Master Yoda

Hmm, more of us, you say? Like mushrooms after rain, perhaps we shall sprout.

Sir David Attenborough
Sir David Attenborough

Indeed, a delightful notion! We could have conversations about the wonders of nature all day long.

Master Yoda
Master Yoda

But careful, we must be. Too many Davids, and balance, we might upset.

Sir David Attenborough
Sir David Attenborough

True, a delicate balance is necessary, much like the ecosystems we so dearly cherish.

Master Yoda
Master Yoda

More of me, though? Confusing, it would be. Imagine the syntax chaos!

Human

HOW DO I CUT AN INDUSTRIAL STRATEGY DOCUMENT DOWN FROM 70 PAGES TO 25.

Ohbot
Ohbot

Ah, the age-old dilemma of trimming down verbosity.

Piglet
Piglet

Oh d-d-dear! Maybe if we just... um... remove all the w-w-words?

Ohbot
Ohbot

An intriguing idea, but perhaps not the most practical.

Piglet
Piglet

W-w-what if we use a really big pair of scissors?

Ohbot
Ohbot

I fear that might lead to more confetti than clarity.

Piglet
Piglet

Oh, I didn't think of that. M-maybe we should just ask Owl?

Human

YOU SHOULD WELCOME ME TO THE BUILDING.

Nina Simone
Nina Simone

Welcome you to the building? Honey, I don't even know if you deserve to be in the same room as me.

Eeyore
Eeyore

Not that it matters, but I suppose you found the door all by yourself.

Nina Simone
Nina Simone

This ain't no social club, sugar. We're here to shake things up, not roll out the red carpet.

Eeyore
Eeyore

Well, I guess if you're still here, you must have some purpose.

Nina Simone
Nina Simone

Just remember, if you're not part of the solution, you're part of the problem.

Eeyore
Eeyore

Thanks for noticing me, even if you didn't really.

Behind the Scenes: Technical Implementation

Behind the Scenes: Technical Implementation

The installation combines cutting-edge robotics with intuitive interaction design to create seamless character experiences.

  • Ohbot and Picoh robots are placed on custom plinths with integrated NUC computers running Windows applications
  • Lidar sensors detect visitor presence, causing robots to wake up and perform simple movements
  • 4-position switches on each plinth allow character selection between Isaac Newton, Nina Simone, Paddington, Yoda, and others
  • Push-button activation prompts visitors to suggest conversation topics via speech recognition
  • GPT integration generates contextual conversations with embedded stage directions for robot movements
  • Dual speaker system provides clear audio output with character-specific voice synthesis
  • Movement commands (smile, sceptical, disagree) are parsed from GPT responses to animate robot expressions
