Remote-Controlled Robot

MIT
2.007, Spring 2007

Overview

I co-designed a remote-controlled robot with my friend Michael Carvajal for the annual 2.007 competition. Although we designed the robot together, we each machined and and assembled our own indivdiual robot from stock materials.

My robot consisted of two components: the car and a torsion-spring loaded device called the "arrow mover." In the 2.007 competition, there were arrows that acted as multipliers for your score. My stategy was to rotate the arrow to 90 degrees to maximize my score (so that the arrow pointed to a 4). The arrow-mover was designed to be placed on the bins at the end of the table using a pulley mechanism, and linkages on the arrow-mover locked it into place after actuation.

SolidWork model of competition table. The number the arrow pointed to would be a multiplier for your score. The arrow-mover we designed would grap onto a horizontal flap on the arrow.

Arrow mover. The aluminum flaps held onto the arrow so that when the metal rod was pulled out, torsion springs would push the top assembly to rotate the arrow 90 degrees.
