4tronix Robo:Bit for BBC micro:bit and Accessories

If you have a <b>BBC micro:bit</b> then you should get the Robo:Bit buggy. Using the basic kit, you can learn about controlling motors and use the accelerometers or compass on the micro:bit to aid navigation and collision detection. You can also make a very cool remote control robot by using another micro:bit and the radio function.<br><br> The <b>Robo:Bit buggy</b> can be assembled very quickly using only a screwdriver. No soldering is required making it a great beginners kit and the chunky wheels and powerful motors mean it works well on any surface.<br><br> There are also available a number of optional accessories to make the Robo:Bit buggy even more versatile:<br><br> The <b>Ultrasonic Distance Sensor</b> (<a href="/search?query=75-0146"><u>75-0146</u></a>) lets the robot detect objects before it collides with them allowing you to program it to avoid them. It can also be used to create a 'follow me' program where the robot tries to stay a certain distance from the object in front of it.<br><br> The <b>Line Follower Sensor Pack</b> (<a href="/search?query=75-0127"><u>75-0127</u></a>) uses two line sensors to follow a black line and keep the buggy on track. You can write more complex programs that behave as required when you meet a T-junction or crossroads.<br><br> The <b>Robo:Bit</b> robotics controller (<a href="/search?query=75-0133"><u>75-0133</u></a>) is a ready-assembled robotics controller board that's ready to be used with your <b>BBC micro:bit</b>, just add battery power (3 or 4 AA is ideal, but not included) and motors of your choice to make your own DIY robot. Use a small box, ice-cream carton or similar to house everything and you can build a really affordable robot for your school, coding club or home.<br><br> Robo:Bit has been cleverly designed so that with a few hexagonal pillars and screws, you can fit the motors, battery box, front casters, line following sensors and even ultrasonic distance sensors and have a very neat and simple robot!<br><br> Robo:Bit uses the ever popular DRV8833 motor driver which allows you to use most small motors that operate in the 3 to 6V range.<br><br> Connections are provided for lots of the BBC micro:bit pins, and all have immediate 3-pin access to power (3.3V) and ground. There are three separate pins for 5V if you need the extra voltage (but don't feed back 5V to the micro:bit as it won't like it!). This is the GVS (Ground, Volts, Signal) system for sensors and servos etc.<br><br> On the left side of the board (the 'front' of the robot) is a set of 4 offset holes into which you can simply poke an HC-SR04 ultrasonic distance sensor. The offset holes and gold plating ensure a good connection, but you can also solder it in permanently for added robustness.<br><br> The Robo:Bit fixings pack (<a href="/search?query=75-0136"><u>75-0136</u></a>) contains screws, hexagonal pillars and a Pololu caster. This allows you to fit standard yellow motors (not included) and immediately get a robot working.<br><br> <br> Also available is the <b>Robo:Bit MK3</b> (<a href="/search?query=75-5014"><u>75-5014</u></a>) that includes, along with the buggy, the line following sensor, ultrasonic distance sensor, integrated pen holder, and the LED light bar.
