Second Design

The device has been designed using cad software, Solidworks. The different parts, which will be cut in the laser cutter, are restricted to be two-dimensional.

Below, it is the first sketch of the robot-arm. This first sketch was designed to use two motors, one to control the vertical movement 180º and another of 360º to create a circular rotation for the gripper and had the possibility to have another motor in the base of 360º. The main objective was only to test two of the three axes of the accelerometer. This was the reason for deciding to use only two DOF.

The second design was created for trying to solve some previous issues. This design is taking in consideration the proximity of the gripper L1 and L2 and also its weight W1 and W2. The second design had the gripper closer to the base; this has multiple connections to attach equipment to it,  like small PCB or the accelerometer see below.

The M0 motor is attached to the side of the base and it creates the 360º movement. The base needs a metal platform to support all the weight of the arm and M1 motor. This motor will have 180º of movement.
