robotics projects.
some of my robotics projects in chronological order
b.h.a.i
Basic. Home. Automation. Interface.
B.H.A.I ("bhai" means "brother" in Hindi) is a virtual agent I created which connects to a smartphone via bluetooth and receives voice commands to control electronic and electrical devices around the house. All the commands are hard-coded and customisable, No A.I. in B.H.A.I. (get it? :D) The commands are converted to text using NLP in the phone app and the text string is sent to the HC-05 bluetooth module. the Arduino then reads the commands from the serial interface and executes the intended action.

gesture controlled vehicle
A wireless gesture controlled robot with an Arduino Lilypad as the transmitter module and an Arduino UNO R3 as the receiver module. The wireless communication was set up using a TX433 - RX433 Radio Frequency transmitter and receiver pair. The gestures were read by a 3-axis accelerometer present on the hand-held remote.

servo controlled LFR
Servo motor controlled Line Following Robot. This was a trial project in which instead of using driving motors to change the direction of movement, the direction control was implemented using a servo motor and a third wheel placed in the centre of the chassis. The robot used only one driving motor to propel and only one servo motor for direction. Using a servo motor provided extremely preciser control over the angle of direction change leading to a higher precision in direction control while using half the power required for a generic Line Following bot.
Power supply: Two 9v batteries.
pick and place robot.
A remote controlled pick-and-place robot running on Arduino MEGA equipped with a custom 3D printed arm for picking up objects. The arm operates using 4 servo motors -- 2 for shoulder, one for elbow and one for the claw -- and is controlled by three single-axis joysticks (one for each joint).
Power supply: AC to 12v DC 30A motor and actuator power supply.
line following robot.
A generic line following robot running on Arduino UNO R3 using a 5 IR sensor array to detect the line and an L293D motor driver.
Power supply: One 9v battery.
