Uni-directional |
8 |
As there are 8 wheels at a time on the ground which gives a good resistance for direction change |
| Portability |
5 |
As its size is not much so it is easily portable |
| Semiautomatic |
14 |
As there are 12 wheels which provides great control, which can be done both manually and automatically |
| To climb steps |
9 |
As wheeled locomotion are relatively high power efficient |
| Speed Control |
0 |
Steps of different height require variable torque, thus speed of the bot need to be controlled. |
| Aesthetic |
6 |
As it is more asthetically pleasing |
| Obstacle detection |
0 |
As there is no relative advantage in obstacle detection |

As there is no scope of turning in chain mechanism |
| Portability |
-5 |
As this design require a lot of components(for chain mechanism) thus increasing the weight and decreasing the portability |
| Semiautomatic |
7 |
As it has good grip with the ground, thus providing more control which can be done both manually and automatically |
| To climb steps |
-9 |
Chain mechanism is not much efficient for climbing steps and it is difficult to accomplish it |
| Speed Control |
0 |
As all the bots are using same motors. |

As there is no scope of turning in wheel leg mechanism |
| Portability |
5 |
As it is compact in size it is more portable |
| Semiautomatic |
-7 |
As the motion is jerkey here there is less control over the operation of the bot |
| To climb steps |
