2. Machine can expand or compress during the run.
3. Locomotion of any part of the machine should be governed by some hydraulic force.
4. Use of batteries or any other source of stored energy is prohibited.
5. Use of any type of electrical motors is prohibited.
6. Use of springs is prohibited.

Competition Rules

1. The run time starts from the moment any part of the machine crosses the starting line and stops the moment last part (excluding the extensions used to control the machine) enters the finish zone.
2. The bot brought will be categorized as follows and will be given advantages accordingly:
1. Wheeled and others: k = 1
2. Crawling: k = 1.2
3. Legged: k = 1.5
3. In case the bot is combination of the above three then the bot will be judged under following priority list:
1. [Wheeled + other combination] = Wheeled : k = 1
2. [Crawling + other combination + not wheeled] = Crawling : k = 1.2
3. [Legged + no crawling + not wheeled + no other combination] = Legged : k = 1.5
4. [Others] : k = 1
4. The score for taking a elevated step, if taken, will be considered only once in the scoring formula. Hence maximum possible value of N=2.(Refer scoring)
5. Any number of team members is allowed to handle the controls. One of the team members can help to handle the tubes.
6. In case of any doubt about the type of bot the judge's decision will be final and binding to all.
7. Maximum of three interventions are allowed during a trial. Teams will have to start from the previous checkpoint. Time will not be stopped during the positioning of the bot.
8. If a bot takes the steps to travel the elevated path then 40pts per step will be awarded.
9. Every team will be given 2 trials. The best run will be considered for the final evaluation.
10. A checkpoint is said to be cleared if all parts of the bot excluding the control mechanism crosses the check point.
11. The tubes containing the fluid should not be taut at any point of time while the run is going on and no direct pull or push force should be applied via tubes.
12. The bot should not damage arena in any form. This might lead to disqualification.
13. It is suggested that people add colours to the fluid used in tubes. This might help them while controlling the machine.
14. The maximum time limit for the run is 5 minutes 30 seconds. If the team is not able to reach the Finish Zone within the maximum time then points will be awarded in accordance to path travelled.

General Rules

1. The teams must adhere to the spirit of healthy competition.
2. Any team that is not ready at the time specified will be disqualified from the competition automatically.
3. The organizers reserve all rights to change any of the above rules as they deem fit. Change in rules, if any will be highlighted on the website.
4. In case of any discrepancy decision of the judges shall be treated as final and binding on all.

Scoring

Total = [(330-T) + (20*a) + (40*b) + (80*c) + (100*d)]*k +(N*20)
T = Total time taken to complete the track, the maximum value of T is 330 seconds.
N = Number of successful steps taken.
a=1; if machine crosses the first check point, else a=0.
b=1; if machine crosses the second check point, else b=0.
c=1; if machine crosses the third check point, else c=0.
d=1; if machine crosses the fourth check point, else d=0.
k: See second and third points of Competitions Rules.
In case of a tie, the average of the two runs will be considered.

Eligibility

All students with a valid identity card of their respective educational institutes are eligible to participate.

Team Size

A maximum of three members are allowed in a team. Students from different educational institutes are allowed to make a team

Certificate Policy

1. Any bot that crosses the second check point will be eligible for certificate of participation.
2. Top three teams will be awarded the Certificate of Excellence.
3. There will be prizes for best design and most innovative design which will be announced later.
