**Object Detection & Avoidance System (ODAS)***

I'm in need to develop an application that will detect other obstacles or objects and respond by controlling an associated object - for the purpose of avoiding collisions with any other given object. For example, this object or device may be a remote control (RC) plane (which my 7 and 9 year old sons may be habitually guilty of constantly crashing into each other, trees, cars, people etc. - while learning how to operate the remote control device). I need an application created that will detect when the Remote Control (RC) car, plane, or boat will crash into another object (like a wall, or even another RC device) and then instruct the RC device to avoid the object that it would crash into.

My thought is, if I can develop a software application that I can place into or onto the RC device, I can better, more safely and more cost effectively teach my sons, and other "potential" students how to navigate remote control (RC) devices, without destroying the RC device.

I'm not a software developer, (I’m an Infrastructure Analyst) and from my research I believe with the use of lasers (or even better - radar technology, and more specifically I'm guessing "Doppler Radar") and a sophisticated computer brain to recognize and detect obstacles, and react for purpose of avoidance - using RTOS like QNX, VXworks, itron or RTlinux, and simple sensoring technology, - I can produce a finished product with the desired results.

Note, another approach could be, possibly there could be no Operating System on it the object at all... the computer will be a hardware only, lower level programming language.

## Deliverables

**_Desired results:_**

· Obstacle avoidance

· Employ the [Adaptive Cruise Control (ACC)][1] technology/theory **(This technology also goes under the names of active cruise control (ACC) , adaptive cruise control (ACC) or intelligent cruise control (ICC).**

· Collision response system (The ability to react within a split second to changing situations)

· ISA, [Intelligent Speed Advice][2] or [Intelligent Speed Adaptation][3]

· Night Vision

· Adaptive Light Control

· Secure design

In the context of "Collision response" applications, long range radar information is desired to be used for very accurate range and relative velocity measurements. The object, (i.e. RC Plane) path and target boundaries are used to predict the probability of an accident. Radar sensors have many advantages, such as accurate measurement capability and resistance to poor weather conditions, but this application cannot be implemented using long range radar only. I've learned that Radar ACC systems, use a single sensing modality, the 76GHz Radar, to perceive the environment in which it operates. This single sensor single algorithm approach to perception problems, however, leads to single mode failures. Although this Radar is unaffected by weather and lighting conditions, sensor data from the radar is extremely limited in the context of trying to interpret an extremely complex and dynamic environment.

**_Bringing it all together (in practice):_**

Ideally this is how the finished product should execute…

1. A potential student of mine will be assigned an uniquely, customized Remote Control (RC) Plane (or helicopter) device running the **"Object Detection & Avoidance System" (ODAS)*** application.

2. Once the RC device is in the air and the student is learning navigation techniques, at any time if the student comes near

a. another student's RC device, and/or

b. a tree, and/or

c. any solid object such as the siding of a building, lamp post, etc

The proprietary **"Object Detection & Avoidance System" (ODAS)*** application will protect the RC device by doing any of the programmable functions:

a. halting the device, suspending it in air, preventing it from going within a pre-defined measurement of inches (or feet) of its target avoidance boundary, or

b. autopiloting the RC device to maneuver around the target boundary object to the defined "safety zone". (The "safety zone" will be a pre-defined distance of absolute avoidance from any given target boundary. For example the programme statement could read "….if within 3 feet (or 36 inches) of any object maneuver in the direction towards the RC handheld remote control device, while keeping 36 inches away from any given target boundary.

This will allow any student to navigate the system, while protecting ongoing damage to the RC device.

***Note ODAS is an acronym which I created. It is not a known standard.**

## Platform

Outstanding concerns:

· What will the application execute on? A chip architecture? If so, perhaps it will need to be designed to run a full-fledged application on a chip, and should be completely programmable to accommodate a range of processing applications. Or

· Freescale Semiconductor has introduced a high-performance 32-bit microcontroller (MCU) optimized for sensor-based collision-avoidance systems.
