Super debris collecting robot

(1/3) > >>

Hi,

I'm a student on my penultimate year.

My project consists of building a robot that will collect debris in a radioactive field, collecting hot and cold debris.

My question is, given unlimited funding what would you have on the robot?

My ideas of current technologies are limited, but if someone can give me a link or directions to research things such as
Nasa robots that would be extremely helpful!

Also can anyone tell me what is the nearest an object can be recognised using a sharp IR range finder?

Thanks,

Steve

EDIT: Oh I also should mention that the robot must be autonomous, so no remote control abillity :(

JesseWelling:
about the range finder....that depends on the model.
this place has a good selection: http://www.junun.org/MarkIII/Store.jsp
the most comon model does 10cm to 80cm but once you get out past 80cm it starts to bounce up and down. which means it's effective range is about 50-60cm (haven't thuroughly tested yet).

There is another that does 4cm to 30cm.

As for what I would use for sensors here you go.

Visual Navigation: http://www.ptgrey.com/products/spherical.asp

Collision Detection: http://www.mysick.com/saqqara/pdf.aspx?id=im0012759 (probably more than one)

GPS: http://www.u-blox.com/products/sbr_ls.html (probably in conjuction with IMU system)

the list could go on but you get the picture

Militoy:
You may want to look into the publicly released documents from the U.S. Army’s ARES program (Analysis of Radiation Effects on Sensors). This program dealt specifically with the performance of IR sensors operating under the influence of radioactive fields. There are several public-domain documents from that program which may have bearing on your project.

Given unlimited funding my Super Debris Collecting Robot would have:

-Cameras for visual feedback so that the robot can recognize the debris. This will require some processing that might be good to do outside of the field, I'm not sure how much processors like to be radiated

-Thus it would have an antenna or wire fore communicating with a processing unit. The communication must be robust enough not to be affected by the radiaton

-It should have one or two arms with grippers to pick up the debris, and a container where the debris can be stored safely

-Navigation equipment, either by measuring the range from two or three known locations outside the field (e.g. the processing unit), or perhaps using an aided inertial navigation system (Accelerometers + Gyros + GPS)

-If the field allows it, wheels or tracks to move the robot. If it is very rough terrain, perhaps legs is better (looks cool too)

-The processing unit should contain planning software of some kind (go there, pick up that etc.)

-All sensors needed for control (joint angles, wheel velocities, current sensors, torque sensors, perhaps force sensors on the grippers etc.)

-Sexy male/female voice (your choice) confirming your every command

And probably lots more.

a must have for all killer robots.

what kind of debris? what kind/amount of radiation?

your probably want lead plating around your electronics. note that stuff can melt or get contaminated with radiation, so material selection and heat transfer is important.

picture putting your robot into a microwave . . .

This robot got f'ed up by radiation. . .
