Automatic Target System Welcome The Automatic Target System (ATS) is a senior project for ME 102 at the

University of California Berkeley. This project is a prototype rotational gunsystem that can locate and shoot at a target designated with a laser.

Circuitry

we connect the motor to the h-bridge, so that we are able to change the

speed and the direction of the motor, last we connect the signal to the

controller.

Mechanical Hardware The electric motor inside the gun is linked to the power supply. After the system starts running, the DC motor with gear box gear ration will begin

to rotate. This gear ratio was chosen because it rotates very slowly so that be able

to detect the light source.

Once the photoresistor detects the light source, it will show a resistance drop,

which will open the transistor gate to supply voltage to the motor inside the BB

gun, which can then fire at the target.

Method and Purpose

The goal of the ATS (Automatic Target System) project is to design a machinecapable of rotating 360 and launching a BB at a target.

1. ATS detects the light source on the target via the photoresistor located on the

device.

2. Motor on the ATS base will rotate to align with the target

3. The spring releases to shoot a BB at the target

Multimedia & Future Development

This is the Automatic Target System in action. In the future we would like

to further develop the device into a two dimensional system that is

capable of adjusting to both horizontal and vertical location of the target.
