IARC7 Landing Gear Design Update November 27 2016


Purpose

Design landing gear capable of supporting impact for a 4kg drone dropped from a height of 2 meters while minimizing shock.

Design Concept – Cantilever Beam

A deflected beam acts like a spring and absorbs energy. This principle was the key idea behind the first landing gear design. Below is a diagram of a cantilever beam fixed on the left end, with a load “P” applied on the right end. Note the maximum deflection is at the tip of the beam on the right.

Applying this concept to drone landing gear, the cantilever beams are legs on the bottom of the drone which deflect from resultant force of impact to absorb the energy as illustrated below.

Therefore, to achieve the goal of dropping a drone without causing damage, the landing gear must be designed to absorb the energy from...

Newsletter October 2016: Motion Control


Many robotics projects involve controlling a car-like robot to accomplish some task. Examples include last year’s Micromouse (below), Line Follower, and Sumo projects.

While each robot has different characteristics and is destined to accomplish a different goal, one thing is the same. They all have wheels. They all need motion control.

Often times in computer science, we find that many projects have the need to solve a similar problem, yet each project has been developing its own solution. This indicates duplicated or “wasted” effort, because the projects could be sharing code where their tasks overlap.

The goal of the Motion Control project is to study control theory surrounding car-like robots, to identify common elements and concepts surrounding these robots, and then to develop a practically useful library or “toolkit” for a potentially large audience. We want to develop a robust and easy to use strategy...
