Tutorial 1

In this tutorial I will explain the mechanical assembly robot Andromina, step by step, in a simple manner and with the use of very simple tools. Little tricks for assembling and improving the robot is also discussed. I would appreciate it if there is any way that is not clearly explain, I requested the information further enlargement. You have to keep in mind that this robot is not a toy and more like a professional robot a toy.

Robotic platform Andromina v.1.2 OFF ROAD., Assembled.

Tools required:

For the assembly we will need several simple tools such as a mini screwdriver and a flat, scissors, Allen wrench 2.5mm, 5.5mm fixed wrench, a soldering iron and tin.

The drwing and dimensions of the robot.

Chassis: Main parts of the robot chassis are 2 acrylic plates, the superior plate and the inferior plate. The assembly of the chassis is shown in the picture above:

View of the 4 servomotors

Andromina robot carries  four servomotors "turrets" to rotate the four CC motors. The servomotors are very strong. The four servos have two ball bearings and several metal gears. You can see the pictures below. There is a picture shows one bearing and metals gears of the servos:
