ROBOT RACER WITH WIRELESS CONTROL

All those peeps interested in robotics, and if preparing for a robotics competition, then you have a chance to improve your problems related to lesser power motor and in efficient driver circuit. Vamsi danda in the blog has worked on it and have found some solutions.

One of them is use of metal geared motor instead of plastic gear and wheel of maximum possible grip. Further, usage of proper motor driving technique and proper battery with less size and more power that works for longer period can be a possible solution. Make strong chases with light weight with maximum possible ground clearance and opt to go wireless.

he has made a prototype of a racer that can reach 15Km/h and can carry up to 4kg of load that can carry a robot arm, gun platform and a video camera. With the help of this platform, he made a robot gun tank. This project uses two micro controllers 8051 at the transmitter and ATmega16L at the receiver and the robot platform is based on the performance of Jonson-H motors. Further, a special motor driver circuit is also designed using relays for driving motors at high currents.

Further, the robot he made can be operated through remote using. RF communication. The encoder and decoder are used at the transmitter and receiver with 8bit secured address and for base motors, high power metal gear motors are used. The geared motors used for robotics applications gives a massive torque of 12Kgcm and the motor comes with metal gearbox and off-centered shaft where the shaft has a metal bushing for wear Resistance.

The technical features involved in the robots are 1000RPM 12V DC motors with Metal Gearbox, 18000 RPM base motor, 6mm shaft diameter, Gearbox diameter 37 mm, Motor Diameter 28.5 mm, Length 63 mm without shaft, Shaft length 15mm, 300gm weight, 12kgcm torque.
