After Romy… Sara… we’re now assembling our third iteration of our jumping robot. We call her Tina!
The parts are still made out of 3D printed PA12, but now dyed in black and red. Now with a new spring-concept for an efficient jump and a complete redesign to achieve higher strength and a more compact form-factor.

HOPP TINA!!!
How did you build the structures of TINA? Mental 3D printing?
Hi! All structural parts are 3D printed out of PA12 (Polyamid 12) using SLS (Selective Layer Sintering) technology.
How does the jumping mechanics work with storing of energy, motors and release mechanism etc?
Really nice work!!
Hi!
The springs are primarily there just to compensate for the weight of the main body when driving around. Apart from the springs, there are only the hip motors involved in jumping, no release mechanisms. Jumping is then achieved by extracting the legs quickly (and controlled) with the motors. For more information stay tuned, we will publish a paper in the upcoming months.
Nice!
what’t the frameless motor’s model of your robot?
Hi!
It is an EC frameless 90 flat brushless motor from Maxon.
