About

In the second year of the Mechanical and Electrical Engineering program at Tokuyama College, a robot contest featuring manually operated robots is held. The competition for the year I participated involved robots climbing to the top of a stage using stairs or a ramp and competing for the fastest time to return to the starting point. With the goal of tackling the shortest route via stairs, I designed and built a dedicated robot. This experience became a valuable challenge that fueled my motivation and growth for the third-year contest.

How it works

The robot designed to climb stairs featured the following characteristics and actions:

Structure: Composed of three tracks, with the front track being liftable. The rear of the robot included a column capable of moving up and down.
Steps for Climbing Stairs:
1. Lift the front track to push onto the stairs, placing the front part of the robot on the upper step.
2. Lower the rear column to push the rear part of the robot up, then advance to the upper step.
3. Raise the column back up for storage and proceed to the next step.

This mechanism aimed to enable quick stair climbing.

Specs and Results

Design Features

Specialized design for stair climbing, featuring a liftable track and a column for pushing the robot upward. These elements enabled efficient operation even with manual control.

Competition Results

By choosing the stair route, I entered the competition but was eliminated in the third round. This frustration became the starting point for my growth in the following year’s contest.

Lessons Learned and Challenges

Through trial and error in designing and operating the robot to overcome the challenges of stair climbing, I honed my creativity and practical skills in robot development. For the next attempt, I strongly recognized the importance of more efficient design and execution.
