Guidance for Roborace Track

Technical events or festivals for engineering colleges is not a new thing. Every year there are lots of events, competition with lot of fun. Every department, every coordinator student of respective event tries to give their full potential to make the event successful. But still many of those who are new to these events (Yes, you should have some juniors for help and also for learning as we do in our Industry) are lack of what things do they need to do, what is their task, what should be done for its success.

Robots ... The most important part of today's life. And Roborace is the first step for engineers to get introduced into robotics. So if you going to arrange Roborace then you need to give participants as much as possible tasks to complete the track within short interval of time. But what if you stuck in thinking which more tasks should be implemented in the track. Don't worry we are here to teach you, tell you the important tasks ( you can also say them as obstacles) that can be implemented on your Roborace track.
Here we go with the list of tasks:
1. Slopes
2. Marbles
3. Oil rig
4. Waterfall
5. Banking angles
6. Hanging bridge
7. Speed breakers
8. Circular turns
9. Obstacles on path
10. Sand
11. Powder or Lime
12. Motor operated propeller

Details of each task:
1. Slopes: Generally standard slopes are in the range of 30-45 degree. Everyone should note that slope angles should not exceed than given standard angle range. For the start, 30 degree angle is enough but if you are ending the race with slope then you should consider to increase the slope angle.
I would prefer to give an angle more than 45 degrees rather 60 degree would be perfect. And if you add speed breaker on this large slope angle then it will be like 'Piece of a cherry on an ice cream'.
2. Marbles: Marbles, one of the greatest obstacles on the track. They reduces the contact of the wheels with the ground surface and accordingly reduces friction, which causes the robot to slip from the surface and try to push it away from the track. So this can be considered as one of the best part of obstacles.
3. Oil rig: When wheels of your robot passes from oil, oil gets stuck to the wheels and due to high viscosity of oil, it becomes harder for wheels to get grip on the track surface. So you can consider to put an oil rig in your track.
4. Waterfall: Waterfall can be used to reduce the speed of the robot. Higher the speed of the waterfall, greater the resistance to the robot for passing the waterfall. One should take care that short-circuit should not happen during the match because as we know water is a good conductor of electricity.
5. Banking Angles: These are slightly different than slopes. As we know about banking of roads, just like that banking angles are made on the track so that the robot will try to go out of the track. Lenght of banking angle track and banking angles can be decides by your own as per requirements.
6. Hanging Bridge: Hanging bridge is the most commonly used task. As the name suggests, hanging bridge is the bridge which is supposed to hang when any object moves through it. It can be made with the help of wooden strips and rope.
7. Speed Breakers: Speed breakers are used to reduce the speed of the robot. If your track is of limited space then you can consider to add speed breakers on it.
8. Circular turns: Everyone likes to drive their bike on curved path. It is just like that. If your track contains some turns or circular structure then one should think about this.
9. Obstacles on path: Obstacles like pillers can be put on the track to make zigzag path for the robot. This will surely reduce too much speed of the robot and increase its time to complete the tasks.
10. Sand: Sand with small stones can be put on the track to make path slippery in some manner.
11. Powder or Lime: Powder or Lime can be put after oil rig for slippery path.
12. Motor operated propeller: A propeller or propeller like instrument mounted on shaft of motor is used in the track. A motor with low rpm (generally 5-10 rpm) is used to rotate the propeller. The purpose of motor operated propeller is to reduce the speed of the robot for completing the track. When the propeller is above the surface of the track, robot will not be able to go ahead till it comes in parallel or below with the surface of the track.
