About the project

It an sense objects in its path and get back and print excuse me on the lcd . It can detect humidity . The robot can move in all directions, it is fully bluetooth controlled it has 2 hands like humans which can move 0,90,180 degree. If a fire has broken out it has stored water and a pump to extinguish the fire.

It an sense objects in its path and get back and print excuse me on the lcd . It can detect humidity, it will print in is dry . The robot can move in all directions, it is fully bluetooth controlled it has 2 hands like humans which can move 0,90,180 degree. If a fire has broken out it has stored water and a pump to extinguish the fire.
