Design and analysis of a hybrid locomotion system for mobile robot

Mobile robots are defined as autonomous mechanical device, which performs automated tasks either by predefined program or under human guidance by using remote control devices. The use of mobile robots is limited due to the lack of an effective locomotion system. There are few kinds of locomoti...

Robots (General) Mobile robots are defined as autonomous mechanical device, which performs automated tasks either by predefined program or under human guidance by using remote control devices. The use of mobile robots is limited due to the lack of an effective locomotion system. There are few kinds of locomotion mechanism used in mobile robot such as wheel, track and leg.

For smooth transformation a new switchover module called track tensioner unit that facilitates the engaging and releasing of track mechanism was developed and included in the system. The three wheeled locomotion mechanism used in this system would enable the robot to move on flat path at reasonable high velocity and maneuverability.
