| Sl No. | Objectives |
|---|---|
| 01 | Robot should be semi-automatic. |
| 02 | Robot hits the striker at different angles |
| 03 | Robot is attached to one side of the board |
| 04 | Robot manufactured should be of low cost |
| Objectives | Weightage |
|---|---|
| semi-automatic. | 9 |
| hit the striker at different angles | 8 |
| attached to one side of the board | 4 |
| cost | 6 |
| Objectives | Weightage | Design Idea 1 | Design Idea 2 | Design Idea 3 | Design Idea 4 |
|---|---|---|---|---|---|
| semi automatic | 9 | datum | 0 | 0 | 0 |
| strike at different angles | 8 | Datum | + | + | + |
| attached to side of board | 4 | Datum | - | - | ++ |

| -Score | - | 0 | -4 | -4 | -12 |
| Total | - | 0 | 10 | 16 | 4 |
| Objective | Score given | Justification |
|---|---|---|
| semi automatic | DATUM | this design is semi automatic as all the functions are controlled by keypad |
| strike at different angles | DATUM | the robot uses a low rpm dc motor to change direction of striker |
| attaches to side of board | DATUM | the bot is mounted on a linear slider mechanism on one side of the board |
| cost | DATUM | the bot is of average cost as sliders and structure are made up of metal and are costly than plastic structure |
| Objective | Score given | Justification |
|---|---|---|
| semi automatic | 0 | equally semi automated as that of Datum |
| strike at different angles | + | is better than datum it uses servo motor to change the angle |
| attached to side of board | - | The bot is not fixed to side of board as it has wheels for movement |
| cost | + | cheaper than datum as it uses spring mechanism to strike the striker |
| Objective | Score given | Justification |
|---|---|---|
| semi automatic | 0 | equally semiautomatic as that of datum |
| strikes at different angles | + | the bot changes direction more efficiently than datum due to its flexible plastic structure |
| attached to side of board | - | is not attached to side of board as it has wheels for movement |
| cost | ++ | cheaper then all the other designs as it uses a plastic structure and DC motors for controlling movement and striking |
| Objective | Score given | Justification |
|---|---|---|
| semi automatic | 0 | it is equally automated as datum |
| strikes at different angles | + | uses servo motor so better than datum which uses DC motor |
| attaches to side of board | ++ | uses rack and pinion which is attached to one side of board and offers greater movement than datum |
| cost | -- | costlier than datum as it uses a robotic clip which is costlier than any other mechanism |
