LizBOT design and prototyping of a wireless controlled wall climbing surveillance robot

LizBOT is an indigenously developed innovative surveillance robot that can climb on a wall and other high rise buildings where the human intervention is either cumbersome or not possible. To keep the robot stuck with the wall, a suction force is required which is generated by a high-speed motor along with an impeller to produce the negative pressure. The robot's forward/backward motion is achieved by two DC gear motors. An on-board wireless camera is used to send the video of the robot's frontal view that can be seen on operator's smartphone. Strongly backed by simulated profiles of velocity and pressure distributions, the prototype has been fabricated in-house. Preliminary results in the form of the robot successfully climbing a wall, demonstrate that the proposed robotic mechanism has a great potential to be used for surveillance, structural fault detection and monitoring of structures.
