No doubt Arduino is number one choice among electronics hobbyists and enthusiasts. IT is easy to prototype and program. Huge community accumulated loads of examples, tutorials and shields for any case. The Arduino board is only a heart with microcontroller inside. In order to have something working, you need either to build a circuit around, use shield or special kit. If you like robotics, check out the RT0006 Bluetooth Car Kit. It is great starting point in building autonomous or remotely controlled cars or robots. The kit includes Infrared remote control module, Arduino, Bluetooth module, short range wireless controller, servo driven ultrasonic range finder module. Each tire is driven by individual DC reduction motor.
The project I am going to talk about next is actually a self-balancing bot or rather an instructions on how to build your own self balancing bot. The electronics features an ATmega328 running 16MHz and 3.3V. It’s out of spec according to the datasheet but it worked for the author. The sensing part consists of a MPU6050 chip which combines a 3 DOF gyro and 3 DOF accelerometer in a small package, which is ideal for a self-balancing bot. The chassis is made from a sheet of polystyrene, since it’s really easier to cut with a sharp knife. The MPU6050 sensor is actually mounted at the bottom of the lowest plate of the chassis so that it can work efficiently. Apart from it he has used a brushless DC motors … Continue reading
When you hear about building robots, you probably imagine the complexity of the process. But his is not always true. It depends on what is your aim. If you want to construct a precise manipulator or even humanoid, then this requires quite some science and research. But don’t get caught with such idea that things are always complex and difficult. Mizchief100 built his Altoid robot using minimum effort and yet it is cool to experiment with. Robot chassis is assembled on single sided prototype PCB with Arduino chip as heart. Robot is driven by two tiny motors along with L293D motor drivers. Sensor bouquet consists of 2 photo-resistors and microphone. Couple RGB LEDs add some personality. This is enough to make it pretty autonomous. You can play with light sources, … Continue reading
Hexapod robot called SAMSA II is a next version of robot SAMSA platform which was based on Atmega128. This one has some nice improvements to do even more with this baby. Overall SAMSA II robot is equipped with three microcontrollers where one takes care of reading sensors, another controls LED dot matrix display and main Arduino mega is a brain. Despite the fact that there is an arduino used, it is programmed with custom C++ code without usage of Arduino IDE what lead to more efficient code. It has some load actually because robot motion consists of 18 Dynamixel Ax-12 servo motors. As we mentioned additional features include 8×8 matrix LED display, IR remote control. Demo program gives several walking and 3D movement configurations.
You don’t need to be a master to build a robot. It can be build out of various parts you’ll probably find at home. SO here it is – a cool robot that simply wanders around and avoids obstacles with sharp IR range finder. Other parts include: couple modified servos for continuous rotation, black&decker battery pack shich serves as robot base, wheels and arduino diecimila as robot brain. All parts are hot glued in to one piece. Great project to do with a kid.
