Building a Jumping Robot Part 2

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.
