ku turtle

KU Turtle is a line following robot that could also be controlled manually using any Bluetooth devices. KU Turtle represented KURC in Yantra5.0 in the category Yantra Racer. The major electronic components included are: Arduino Uno: A micro-controller based on ATmega328 microprocessor. Lithium Polymer (Li-Po) battery: Used for its high power to weight ratio. DC Geared Motor: A normal brushed DC motor fitted with gears to increase torque in expense of speed. The motors (four), KU Turtle possessed were of 100 rpm, 12 V. L293D motor driver IC: To control the DC motors (Speed and direction). Photodiode Module: A sensor to detect the color black or white (i.e. IR reflecting or absorbing). In our case we used three active photodiode module for more accuracy. Bluetooth Module: The bot was connected to a Bluetooth device via Bluetooth and controlled by an android app. The casing was prepared from aluminium pieces and Polyethylene Terephthalate (PET).

KU turtle is a line following robot prototype whose actual application can be realised.

KU BULL

An auto fighting bot is a bot that search its opponent in the arena and fights to damage or to push the opponent bot out of the arena. The bot that fought in our side was named “KU BULL” which is a non-destructive sumo bot that fight with the opponent bot of the same kind.

The major Electronics components used in “KU BULL” include:

  1. Arduino Uno: A micro-controller based on ATmega328 microprocessor.
  2. Lithium Polymer (Li-Po) battery: Used for its high power to weight ratio.
  3. DC Geared Motor: A normal brushed DC motor fitted with gears to increase torque in expense of speed. The motors (four),
  1. KU BULL possessed were of 100 rpm, 12 V
  2. L293D motor driver IC: To control the DC motors (Speed and direction).
  3. Photodiode Module: A sensor to detect the color black or white (i.e. IR reflecting or absorbing). In our case we used six active photodiode module for more accuracy.
  4. Ultrasonic Sensor: A sensor that detects the object in front it and how far it is. We used two ultrasonic sensors (one in front and other in back) to detect the object within 180 degree of rotation.

The casing was made of aluminum pieces, sheet metal of various gauge thickness and weight density to maintain the specified weight limitation of 4 kg. Similarly, the specified dimension was 30cm*30cm*30cm and limit of dimension was fulfilled.

The bots were needed to fight inside the arena of regular polygon of 90cm with 2inch wide black line at the edge of the arena.

HUSKY : AN AUTOMATIC FIGHTING ROBOT

An automatic fighting robot (also known as Sumo bot) is a bot that fights (destructive or non-destructive) and damages or push the opponent bot out of the arena. The bot that fought in our side was named “HUSKY” and it was a non-destructive sumo bot that fought with the opponent bots of the same kind.

The major electrical & electronics components used in “HUSKY” include :

  1. Arduino Uno R3:- S micro-controller based on ATmega328 microprocessor.
  2. Lithium Polymer (Li-Po) battery:- Used for its high power to weight ratio with a typical cell voltage of (3-7) Volts.
  3. Geared DC motor:- A normal brushed DC motor fitted with gears to increase torque in expense of speed. The motors (four), HUSKY possessed were 100 rpm, 12 V.
  4. L293D motor driver IC:- To control the DC motors.
  5. Potentiometer:- Which is also called the variable resistor used in Voltage Regulator.
  6. Photodiode module:- A sensor that detects the colour usually black or white. In our case, we used four Active photodiode modules.
  7. Ultrasonic sensor:- A sensor that senses the object infront of it. We used two ultrasonic sensors in the front & back sides of the bot which detected the object within 180 degree of rotation.

The casing was made of sheet metal of various guage thickness and weight density to maintain the specified weight limitation of 3 Kg of the bot. Similarly, the specified dimension was 25 cm*25 cm*25 cm and that limit of dimensions and weight was fulfilled.

The bots were needed to fight inside the arena of 2 meter diameter with 5 cm wide black line at the edge of the arena.

ku rover: a MULTIROBO HEXACOPTER

KUHOVER is an aerial unmanned vehicle also known as KU-Copter in Kathmandu University. It is a multi-rotor hexa-copter, remotely controlled UAV. The approximate weight of the finished model is about 1.4 kilogram. KUHOVER uses six 1000KV motors and a 5200mAh battery to power the system. The approximate flight time is about 10-15 minutes. The range of the six channel radio trans-receiver is about 1.5 kilometers.

Although the competition was postponed and later cancelled, the development and research on the project are still in progress.
