Building a Jumping Robot Part 2
HTML-код
- Опубликовано: 27 сен 2021
- Last year I designed a spring powered jump mechanism and now I am back with a whole jumping robot. Its main part is servo powered spring compression mechanism which uses herringbone gearbox to increase the torque needed to fully compress two ASG springs. After testing the mechanism I added two motors, flexible wheels printed from PETG and an Arduino RC control circuit which gives it the ability to move like a normal robot and jump when it needs to. To power the whole robot I used a small 2S drone battery and I wouldn't recommend using lower voltages because the servo might not be able to fully compress the springs.
Overall this robot was a lot of fun to work on because I always wanted to have one of those Jumping Sumo mini drones and since I never got one, I built it myself. However it is still far from perfect and there is a lot of space for improvements. For example it would be better to print wheels from elastic filament like TPU, it should be at least 50g lighter (It weighs around 340g),the main frame should include space for electronic components and it would also be cool to add a small fpv camera to it. Furthermore in my Arduino circuit I used 5V Arduino Pro Mini and RC receiver but now when I think about it it might be better to use the 3.3v Arduino version and NRF24 which would take less space and give more steering options. Maybe I will make another video about those upgrades in the future but for now it works which is kind of surprising since it is my creation. And to achieve higher jumps it's better to ride on hard surfaces because I noticed that grass dampens the jump power a little bit but it's still good enough to jump on or over small obstacles.

This content is criminally underrated, just found this channel, keep doing what you’re doing!!
Hi and thanks! It really does mean a lot to me. Right now I am a bit busy with a CanSat competition so there isn't a lot of content on my channel,but as soon as I am finished with that, oh boy I have so many ideas for new videos. By the way, I saw your video about Nerf face tracker on reddit for the first time and that’s how I discovered your channel. You have some great stuff! I love the way you edit your videos and also that spiderman robot is cool as hell. Keep up the good work!
I noticed during the jump testing, the rig was also trying to rotate. As it was ascending the pipe, I believe the sleeve (sliding on the pipe), was binding to the pipe…essentially acting like a brake. I think to remedy this situation you’ll need another sleeve near the bottom (sleeves on the top and bottom of the rig).
Love the end results. How you manage those issues with trials and errors but it was worth it. Keep it up.👍👍👍👍👍👍
Love the wheel design. They did an impressive job of absorbing the impact. Very cool project. One tip to consider might be mixing the printing orientation of gears and their shafts as 2 separate interlocking pieces for maximum strength.
It's like a parrot jumper, very nice!
Fantastic job, the mechanical design is great. Powodzenia ;D
Love it!
Making a Watch Dogs 2 jumper, ordered a Sumo jumper on eBay to rip for this(already printing parts I expect will die after a couple jumps).
My car will have a tad bit of heft. Proper camera, wifi, speaker, ultrasonic sensor. I had a similar idea of using an airsoft mechanism and spring. My thought was to use an M140 spring I've had laying around for ages.
I'll have to print your design and see what I can pull off :)
I intend to add a catch for the fully compressed spring so it's ready to go when I want it to.
I'd like to get Starlink, connect my jumper, drive to my buddy's house and make it insult him.
clicks tongue*
*And then I want to make one that flies*
WOW, that video deserves more views mate....KEPP it UPP
Awesome project man, really interesting design.
Darpa Sand Flea
you can try adding tiny wheels to the bottom of the piston that pushes off the ground for a smoother ride
Nice job and great tutorial
thanks for sharing this video...verry good..i think should try make one..
If you make it don’t forget to share! This project was fun but it still has a lot of room for improvements so feel free to remix it as you will
That's so cool man!
Jumpstarting like a gyrocopter is maybe a little less clunky
Next variant should contain a Teensy board, IMU, closed loop BLDC on wheels and a highly complex motion algorithm to control the direction of the robot during its flight using the wheels as reaction wheels or gyroscopes.
Exactly what I want to do
Just here asking if anyone has any interesting sources on this sort of robot. Really trying to get a firm understanding of the multitude and capabilities of jump techniques
Check out Elliot Hawkes jumping robot. That thing is really insane, and I am planning to try a similar design in my jumping robot V3
0:23 What do you have in the yerba mate machine box?
Future project 😉
It is so cool!
Super vidéo 🇨🇵😘
nice video! btw will there be a part 3 of this project?
Thanks!
To be honest right now I want to focus on some different projects ,but this robot still has a lot of space for improvements (Like reducing the weight, printing wheels from TPU, adding FPV cam or increasing jump height). So one day I might make another video about it but it probably won't be anytime soon.
Will you upload the CAD design process on some future videos?
For the test rig, adding a second loop at the bottom will fix the issue. What is happening is there is rotational force which causes the lip of the top loop to catch on the pipe, by adding a second loop at the bottom this will stop that being an issue, it will still add resistance, but it should stop it catching the same way. You can also add extreme fillets to either sides of the loops so that there is no place to catch (this would require increasing the thickness of the loops to account for a 1cm+ fillet)
NICEEeeee!
cute owo
Like Rainbow Six Siege :)
Where did you get your servo motor from?
Aliexpress I think, but you can buy those in many online shops with electronics. It doesn't have to be the same model as long as it has similar dimensions.
