The Robogaia 2D Robotic Obstacle is a tool that allows your robot to determine the distance to obstacles and walls and to avoid them.

About this project

1.What is it?

The rangefinder is a tool that allows you to determine the distance to obstacles and walls in order to avoid them. It is perfect in robotic applications where the robot needs to move and go to a determined position in unknown territory.

2. Current condition

 So far we  built 3 versions . We are working on the final version (v 4.0)  which is very similar with the present version (v 3.0).

Version 3 (present version) is smaller and lighter than version 2.

The final version will have  exactly the same enclosure  as version 3 .

3.Description

It has 2 sensors placed at 90 degrees that read the distances simultaneously.

Here are some of the unit details:

  • detectable range: 20 cm to 150 cm (6 to 60 inches )
  • 7.5 degrees angular resolution
  • 2 scans per second
  • 180 degrees view
  • easy readable output data in text format
  • easy interface with other boards it comes pre calibrated
  • USB interface power and data  , also SPI and RS232

4.Team

We are a small team of engineers from Cleveland and we like to tinker with stuff and work on all kinds of interesting projects. In the past we participated twice at Centennial Regolith Challenge, a competition organized by NASA and California Space Authority. This is where we came with the idea of creating a cheap obstacle detection unit. Since we payed all the costs for the robot, transportation, and the competition fee, we did not have a lot of money to spend and we lacked proper sensors. The obstacle detection units that are on the market today start at more than a thousand dollars, which we could not afford. Also Kinect would be great if it would work reliably in daylight.

5.Goals

Our goal is to create a cheap 2d obstacle sensor that could be used in robotics

7.Software

So far we have a C and a C# API and graphical interface. We plan to develop a Python interface. In the picture there is the graphical interface that is written in C# and allows showing and capturing range data .

We also plan to create an interface for ROS (Robotic Operating System)

8.PCB

The PCB was designed in Eagle Cad and sent out to a PCB manufacturer.

Here are different versions of the PCB.

11.Tools

We used mainly a  CNC machine to build the enclosure. The CNC is driven by an  computer with LinuxCNC installed. This proved to be enough for very good results.

Risks and challenges

In case of a reasonable demand, all units will be built by us. If the demand is higher the parts of the unit will be outsourced locally which means a longer lead time. We have experience with building and shipping products, and also we have most of the equipment in house. With all this, we try very hard to minimize the risk.
Also if there is a higher demand there might be some parts shortages which might delay the production. Fortunately the parts could be procured from multiple places.
