Ohbot2 - A Robot Head to program from your PC

£10,671

94

Please note that the Early Bird reward will be delivered in December 2015 not 2016 as listed.  We've added a second reward with this corrected but we're aiming to ship all early bird rewards in December 2015.

Ohbot2 is a robot head that helps children to learn programming and computational thinking.  You can choose to have one fully constructed or as a kit that you put together yourself.

It has seven servo motors:

It has graphical programming software that allows children to program it to move, speak, 'see' faces and 'hear' spoken words. See program examples.

Launch

Since we launched Ohbot1 in March 2015 we have delivered hundreds of robots to children, teachers, academics and enthusiasts across the world. 

Ohbot1 generated a lot of excitement. Children immediately engaged with the idea of a robot head that they can program to tell stories, greet school visitors or to boss adults around.

Through a partnership with the University of South Wales, we sent Ohbots on working holidays to primary and secondary schools in Wales to help us establish how Ohbot would support learning in computer science and programming. Children programmed their robots to do useful work around their schools "I've learnt to program robots to make them like they're a real human which was hard" one young roboticist reflected on the experience of programming Ohbots. See the ITN report on the project here.

Ohbots also took part in the BBC's Make it Digital tour. See this BBC News report.

Feedback on Ohbot1 has helped us to understand the potential of Ohbot as a fun learning tool, and as a sibling to the floor turtle in primary education.

"The only robot I have seen that might introduce artificial intelligence ideas in primary." Helen Caldwell, University of Northampton

"I think the best thing about the Ohbot is that it is a suitably challenging progression for kids to move on from Scratch - a real gap in the market at the moment. The interface will be familiar to pupils but they will then need to think about controlling and timing the motors to make a real robot move and speak!"  DigitalKatie

Professor Adrian Oldknow of the National Stem Centre on Ohbot.

Ohbot2

Our campaign is to make a new version of Ohbot. Currently it takes a long time for us to produce all the parts. We've also found that assembling Ohbot from a kit of parts is time consuming.

So we have teamed up with a local company to make Ohbot2 using injection moulded parts. This will make the robot much easier to assemble for the people who buy it as a kit and also reduce the time it takes us to make parts.

We have all of the design finished and prototyped with 3D prints but the moulds are very expensive to make. We need total pledges of £10,000 in order to bring our designs off the screen and into the real world.

We are also taking the opportunity to make Ohbot even better so it will have:

A new controller board will allow additional sensors and servos to be added. It will also make the power supply connection more reliable. Arduino enthusiasts have the option to write code to run on it directly, without the need for a PC to be attached.

A more expressive mouth, controlled by an extra motor allows Ohbot to look sad and most importantly happy!

New eyelids which cover the top of the eyeballs to show a greater range of emotional expression.

Improved software will include exciting new blocks such as one that allows Ohbot to respond to live data from Wikipedia.

Risks and challenges

We are prototyping our new moulded parts with 3D prints and using an established and experienced local injection moulding company to keep the risk of something going wrong during production to a minimum.

We're confident that the software is stable as it's been in use all summer and the new controller is working well with our prototypes.

We'll try our absolute hardest to get the first 100 Ohbot kits delivered before 15th December 2015.
