Robotic gripper and Arduino. Tutorial about a robotic clamp with Arduino.

The new robotic gripper Andromina V.2.0 is the most advanced gripper that currently exists and has many applications. In this second version, the clamp has been greatly improved, the opening and closing of the clamp can be controlled by an encoder and a limit switch. The main advantage of this clamp is that it is controlled by means of standard radio control servo motors. These can be controlled directly from any Arduino board or any other board, such as Raspberry Pi, Beagleboard, Picaxe etc .... In this post we show the new mechanical design of the 5 grippers Andromina V.2.0. There are 5 different designs of clamp where we have varied the number of fingers that each clamp has and we can choose between 2, 3, 4, 5 or 6 fingers. We can also choose if we want a clamp with one, two or three degrees of freedom.

In the following picture you can compare the 5 different models of grippers, Andromina V.2.0. In this picture you can see grippers with a single degree of freedom, with a single servo motor RC.

New Andromina robot v.1.0 (ON-ROAD) (Arduino, Raspberry, PICAXE, ROS robot)

I am designing the new Andromina robot, ON-ROAD version, it is similar to Andromina robot v.1.2 (OFF-ROAD). This new model is going to be small, cheap and simple. It is also compatible with all Arduino boards, Raspberry Pi, PICAXE and more. The next pictures show the new design.

The main features of the robot are maintained its 4 wheel steering-wheel drive and 4 wheel supplied by the 4 DC motors (in yellow in the figure below).

In this post we show the Andromina robot which it is controlled to a IR remote control of a PHILIPS TV. The robot has the basic configuration, with an Arduino UNO board, a proto shield modified with a voltage regulator of 5v, a motor board and a IR remote control. In this configuration the robot sketch is a bit complex and we can add a lot of movements and functions. In the sketch, we have set preset buttons with a maneuver or buttons for example to accelerate or turn the robot.

These videos show the main features of Andromina robot, this robot carries 4 directionals wheels that they can turn 90º to 0º and 90º to 180º. Four standard servomotors control the rotation of the wheels and they can rotation  independently of each other.
