KONDO LAND Attraction Guide
Various kinds of 6 obstacles set in the race course are as follows;
The 1st attraction : `Gattan` Seesaw
A big seesaw, which size are 500 mm in width and 700 mm in length with an inclination of 15 degrees. A point getting push button for one point is set. The steep slope is not easy for every robot. It is important for robot not to slip feet.
Degree of Difficulty：★☆☆☆☆
The 2nd attraction: Magic Wall
A road, which size are 600 mm width and 1,000 mm in length with 2 pushing robots. Magic Walll is hard for light weight robots. Robot needs weight and power for push out the Wall.
Degree of Difficulty：★★☆☆☆
The 3rd Attraction: Mootan House
A big tunnel, which size are 1,200 mm width and 1,200 mm length with a pitfall (400 x 400 mm). Two push buttons for one point are set in the House. Ten point button is set out of the House. One push gets one point and ten times push get 10 points, however 11 times push makes point zero. Robots fallen into the trap, cannot return the race course. Controler can not see his robot in the Mootan House from controling space. Controler can move by the advice of his assistant. Robot can be attached wireless camera and be controled through image on PC.
Degree of Difficulty：★★★☆☆
The 4th attraction: Wobbly Bridge
A Board Bridge, which size are 400 mm width and 700 mm length, revolves on an axis. If robots walk the edge of bridge, robots fall down from the bridge. Robots have to walk slowly in the center of board. Robot needs to have a low gravity. Ten points button is also set beyond the bridge and one point button is set in the slope to the Reverse Street.
Degree of Difficulty：★★★★☆
The 5th attraction: Swirling Straits
Robot fallen down from the pitfall of Mootan House, has to pass through the most difficult Swirling Straits. Space of 900 mm width and 1,000 mm length, filled with sponge balls is too hard to walk. Robots need to have long legs.
Degree of Difficulty：★★★★★
The 6th attraction: Reverse Street

The time record race carried out twice. All robots had the best record in the 2nd race. The 1st place was Tic-Tac2 which cleared the obstracle course for the first time with 2 minutes and 2 seconds. The 2nd place was Metalic-Bio and the 3rd palce was Isoko Rescue. The MVP was Metalic-Bio. The special prize was Garutan because of getting 16 points in the point getting race. The result was described here. The best race video of each robot was uploaded to YouTube IKETOMU Channel.
The 3rd Place, Isoko Rescue, 4-Legged Robot by Kenmotsu-san, which was changed from 6-legged robot and made legs long.
The 2nd Place and the MVP, Metalic-Bio, 6-Legged Robot by Morinaga-san.
The 1st place, Tic-Tac2, 6-Legged Robot by Amino-san, which moves just 6 servos. Tic-Tac2 cleared the obstacle course for the first time within 3 minutes (2 minutes and 2 seconds).
Addtionnal race, point getting race within 5 minutes was also carrid out. Because almost robots did not try to get point in the twice time record race. Jaaga, Garutan, Tic-Tac2, Metalic-Bio and YASHIGANI could get points. Garutan got 16 points and got special prize.
BLACK TIGER L45 also could get 10 points in the point getting race as follows;
