Building a Raspberry Pi Robot – CamJam Video and Slides

A couple of months ago, Dawn Robotics went to the fantastic Cambridge Pi Jam organised by Michael Horne and Tim Richardson. Whilst there, I gave a talk on building a mobile robot with the Raspberry Pi (such as the camera robot we talk about in this blog post). The talk was aimed at quite a high level, and looked at 7 key areas you should think about when building a mobile robot.

Well, I recently found out that there was a video of the talk online (along with videos of all the other talks at the Jam). Therefore I thought that I’d link to it here, along with the slides for the talk. The sound quality is not too great, and I need to work on my presenting style, but hopefully it’ll be useful to people thinking of building their own robot. If you’ve got any questions, or would like more information on any of the areas talked about in the video, please post on our forums.

Also, for those that are in the area, we’ll also be giving a talk at the Linux User Raspberry Pi Jam being held in Poole this Saturday (5th April 2014). A small number of tickets for the Jam are still available here. This talk will mainly be about using the Pi with an Arduino, but we’ll still try to squeeze in some robots. :)

Using the Pi Co-op as a General Purpose I/O Board for the Raspberry Pi

We released the Pi pi_co-opCo-op, an Arduino add-on board for the Raspberry Pi back in the middle of January. But for various reasons, we haven’t had the time to do much promotional work, and explain to people why it’s so cool, and why you’d actually want to add an Arduino to your Pi.

To fix that, we’ve created a video, because reading text can be really boring :) , and then, we’ve written this blog post to show you one of the really useful things you can do with the Pi Co-op. We show you how you can use your Pi Co-op as a general purpose I/O board for the Pi.

So now, instead of having to buy loads of different add-on boards for your Pi, you can just buy the Pi Co-op here. :) You can use it as an Analog to Digital Converter (ADC), you can use it to connect to 5V devices, you can use it to generate PWM signals, and you can use it for I2C. To top it all off, you can also control all of this functionality from a high level language such as Python.

L293D Motor Driver

L293D Motor Driver

We’re now stocking some Integrated Circuits (ICs) in our store for your robotics projects.

MCP3008 Analog to Digital Converter

MCP3008 Analog to Digital Converter

The L293D is a stalwart of many robotic projects. The are lots of newer motor drivers on the market, but the L293D’s DIP packaging and rugged design make it a great option for quickly breadboarding up some motor control for your project.

The MCP3008 is an 8 channel, 10bit Analog to Digital Converter (ADC) that is a very popular option for projects that need to monitor analog signals. The MCP3008 is an especially good match for the Raspberry Pi which doesn’t have an ADC built in, but which can talk to the MCP3008 using its SPI interface.

New Digs

It’s been really hectic here over the last few days, as we’ve been busy moving into our new offices, but we’re finally in, and can now get back on with making robots. :)

We’ve been lucky enough to secure a place in the new Technology Incubator that recently opened at the Bristol Robotics Laboratory. The Bristol Robotics Laboratory is one of the biggest and best robotics laboratories in Europe, and this move gives us much more space, and a much better environment for developing our new products.

Introducing the Rover 5 Seeeduino/Arduino Robot Kit

Front View

Front View

Well, it’s taken us much longer than we would have liked, but finally, we’re pleased to announce the release of a brand new robot kit based around the popular Rover 5 chassis from Dagu. This robot kit combines the Rover 5 chassis, with a Seeeduino (an Arduino compatible controller board) to give you a complete robot with loads of great features. The kit is easy to assemble, and accessible for beginners, whilst providing the flexibility that more experienced robot builders need to build advanced robotic projects.

We’ve built this kit by combining components that we already sell in our store to create a complete robot. All the components have been selected and tested to ensure that they work well together, and we’ve written a manual describing step by step how to assemble the robot. We’ve also created sample code in the form of a wall following behaviour so that you can get up and running with the robot really quickly.

Buying the kit gives you a great saving compared to buying each of the components individually, but even if buying the kit is not for you, because you have some of the components already, we hope that the manual and sample code will provide some useful ideas for your own projects. Check the kit out here, and let us know what you think.

 

 

 

 

New Products

We’ve recently added some new products to our store. First up are a couple of new Arduino shields from Seeed Studio. We now stock their WiFi Shield and their Relay Shield, so now for almost any application, we probably have an Arduino Shield you can use. :)

Secondly, we’re pleased to announce that we now stock the BerryClip from our friends over at Raspberry Pi Spy. The BerryClip is a small affordable electronics kit that is a great project to get started with on the Raspberry Pi. It consists of LEDs, a switch and a buzzer, and provides a perfect introduction to both software and hardware interfacing.

Sensors

One of the main things missing, from the Dawn Robotics webstore up until now was sensors. Which is a fairly glaring omission when you consider that sensors are a large part of what makes a robot, a robot…

Well, we’ve now fixed the problem, with a range of sensors from Seeed Studio. Your robots can now detect walls and obstacles with the Ultrasonic range sensor, navigate with the 3 axis compass, and follow lines using the IR line sensor. For the full range, see the sensor section here.

Also, one of the other advantages of getting these sensors, is that it now allows us to put together more complete robot kits (the greyed out coming soon items on our main page). These will be bundles which give you all the parts needed for a complete robot, coupled with a discount for buying everything in one go. Hopefully, this will help save money, and reduce some of the confusion for people just getting into this fascinating hobby.

New Products From Seeed Studio

Seeeduino V3.0 Atmega 328P

motorshield_03

We’re pleased to announce that we’ve recently become a distributor for Seeed Studio, and as such we now have a brand new range of exciting products that you can use in your robotic projects.

Chief amongst these is the Seeeduino, Seeed Studio’s take on the Arduino, and a number of very useful Arduino Shields. Seeed Studio have really tried to innovate with the Seeeduino, making a number of changes, rather than just blindly ripping off the Arduino design, and as such, it offers a very useful, and affordable controller for your robotic and electronics projects.

That’s not all we have from Seeed Studio though, we have motors, a breadboard power supply and more. So, please, check out the new range, and start planning your next robot. :)

Up and Running

Ok, so the store is now up, along with our forums and this blog and tutorial website. Dawn Robotics is open for business!

You’ll probably notice that things are a bit sparse round here at the moment, but over the coming weeks, months, and hopefully years, we aim to expand things a lot. We’ll be bringing in new products for the store, providing tutorials and news for the robotics community, and generally making this a much more useful site for people interested in learning about, and building robots.

So, watch this space! :)
