Ranger II snobot

Paul Flint and I came across a ranger II storm series wheelchair manufactured by invacare, as we are rather cheap guys we spent a couple months reverse engineering the motor control board. Built an arduino shield to send the control signals to the motor controllers. and you can see snobot Mark I in the picture and Mark II in the video. all schematics have been released under GPL v3 and more information can be found at http://docbox.flint.com:8081/snobot

  • Actuators / output devices: Differential Drive Motors
  • Control method: arduino Serial via computer connected via Wifi
  • Operating system: Linux Mint 32 bit
  • Power source: 2x12v 500AH batteries + 24v UPS charging system
  • Programming language: Arduino ide
  • Sensors / input devices: Parallax ping sensor
  • Target environment: indoor, outdoor

(that)s no bot : it’s a T-shirt

In the words of obi wan: “(that)s no bot : it’s a T-shirt” with bleeps, street and people’s chests. 

More information.

I will post another video of it during the mark one stage. 

**Video of it mowing the lawn, **

Unfortunatly the only person who has a video of the snobot was our neighbor back up in vermont. I will try getting the videosent over via email so I can post it.

lol

+1 for sarcasm and truth. I did feel a little ripped off after 16+ minutes… :slight_smile:

The shorter video was more rewarding. I do like seeing people crashing into things while riding on their chassis haha It looks like a beast.

Teach Eva not to turn the camera 90deg and 45deg!

Yeah thats better. Are you

Yeah thats better. 

Are you getting this CTC? If you want a video of your robot trying to throw of its rider, climb on yourself instead of risking the lives of your family :wink: You even get a tilted camera position for dramatic “blair witch project” effect.

Well done!

Just to specify, I am the

Just to specify, I am the guy with glasses and riding the robot :slight_smile: eva is acting all affronted about the criticisms on her video taking abilities :slight_smile:

Family carrying robot

You’re a brave man :wink:

Check out this page by  Chris the Carpenter (=CTC) a couple of years ago. 

trying not to be negative

I generally try not to be negative and try to encourage other bot builders but this one I have to say Where’s The Beef? I couldn’t sit through the 16 minute video of a description of a robot and here’s what I got from the second clip:

Looks like you took a comfy, joystick controlled power chair and converted it into a not-so-comfy, computer keyboard controlled power chair. That’s not an improvement. Now I’m not the best postitioned to critize others as I haven’t gone very far with my bots either but at least they fit the description of the term ‘robot’.

Guess I’m just in a speak my mind mood today but to all LMR bot builders - a remote controlled platform is not a robot. There are some seriously creative people on here but there’s also a lot of ‘robots’ that are no more advanced than a remote controlled toy car. I worry myself that I haven’t done enough to merit a ‘robot page’ here but let’s up the standards a bit. I realize for some folks just getting an obstacle sensor working on a platform is an accomplishment and everyone has to start somewhere but let’s get a little meat into the project and show your work even if it’s held together with hot glue and string.

Looking forward to the next phase and please, we’re more interested in the robot than we are (no offense) with you. :slight_smile:

Thanks,

Thanks, I appreciate the advice, I am not the best at video production, As is shown in my highly critisized videos. I can say for any bot builders that are in Vermont, if you want to view the bot in peroson please go to the vermont mini-maker faire this weekend. The snobot will be there. 

 

Warmest Regards,
