HoverBot v2
Tweet
Hey everyone!
I learned loads of stuff while building the ‘HoverBot’.
http://www.rcindia.org/self-designed-diy-and-college-projects/hoverbot-xtreme/
So, after realizing that there’s lots of room for improvements, I started working on the HoverBot v2.
Here’s the new features:
1) Semi-autonomous (using Arduino Due). Sets ESC throttle end points at each startup. Detects obstacles and stops the HoverBot.
2) Differential steering for better control, agility and torque-balance.
3) Full brushless setup, improved skirt and compact design.
We might add gyro stabilization (as I have a quad board now!) and onboard cam. Then there's a 2-DOF arm built waiting to be attached.
Now those who have seen the vids of HoverBot can just imagine the speed this one can achieve! Will post vids soon!

Awesome build!!!!! The whole concept of design is futuristic. Not only design but you have also added feature of automated system. This one is completely new thing i have ever seen.

Re: HoverBot v2
Thanks Swizera and Dharmik!
Quote from: Dharmik on March 17, 2012, 09:27:42 PM
also added feature of automated system...
I've also written a program for auto-lift and auto-navigation(using sonar) . And it works great!
But the group of college friends (juniors) I built this for wanted it to have radio control as well. So now it's semi-autonomous.
One of my friend is working on machine-vision. When it's done I might be able to make the HoverBot autonomously chase humans. (or cats!)

Re: HoverBot v2
its not a simple apreciation Swapnil..!! but you deserve it.. because making a full hovering bed is a tougher job.. but you made it here.. simply.. only a few can achieve this.. even you can look around the world, then can only find a very few machines as sucessful.. so, its moments of happy.. and proud.. thanks for sharing your works to us.. keep it up and go for even bigger machine.. have a nice future..

Re: HoverBot v2
The 2 DOF arm turned out to be too heavy so we just added the gripper.

Re: HoverBot v2
And the auto stop using IR sensors. The range is not much. Will soon change it to ultrasonic.

Re: HoverBot v2
The differential thrust was achieved by using elevon mixing (with zero aileron diffetential) plus one programmable mixing. The torque is balanced by proper trimming.

The material is an old car cover dipped in a secret solution (
) for making it totally airtight. It also has duct tape at bottom for protection on tar road.

Re: HoverBot v2
Does anyone have experience with laser range-finders?
I was wondering about the color scheme. Would black+silver look better than black+ yellow or black+red? Or should I let it be as it is (i.e black+white)?

Re: HoverBot v2
Here's a test bot I made to configure and check the diff mixing before applying it on the HoverBot v2. It turned out to be really fun!
Setup:
500 RPM side-shaft brushed motors x 2
HK 30A brushed ESC X 2
LiPo 2200mAh 20-30C

So much to do and so less is done.Hurry up!
Re: HoverBot v2
OMG...
u did so well sir...
Damn good work. When you say it took TWO days to make it,what exactly do you mean?
it took only TWO days to develop the design,research,assemble things together,develop the code etc etc?
please enlighten me.:-)

Re: HoverBot v2
Nah! Two days to make the hull (that is, base + skirt) and fixing the thrust motors.
Total assembly time (including programming the arduino and setting channel mixes) was 4-5 days.

Re: HoverBot v2
Brushed? The HoverBot uses brushless ESCs. If you are referring to the 'FunBot' ESCs, I got them from Vivek bhaiyya (rcelectro.com)
