The main problem was to build a very compact dragging system between the servomotor and the wheel.

A follow focus system
I have developped a follow focus system. It's used to control precisely the camera's zoom & focus.
A controled vice
After the sine vice, I wanted to develop a fully controled standard vice. I only developed the Z axis.
The principle is simple, I use a screw-wheel system with the right angle to have an irreversible system.

A ruggedize modular robot
The idea has been to develop a ruggedize robot with modular features. The power transmission system used is caterpillars. The main drawback has been the low efficiency, about 90% losses.
3D Model. The batteries are in blue and the motor control units in red.

A virtual view, close to reality.
The real robot. I added a mask to protect the electric parts.
The electric parts. It's a mess.
This is an unfinished version of a new shape, lighter and stiffer.

Mandrel
This is based on a real system - Redstone wireless drilling machine. This permits to change quickly and easily the mandrel. The torque is transmitted through the balls.

Organisation with a CAD model
The target was to create a cupboard for shoes and a special ambiance - created with led lights - behind the dividing wall.
We can see the light's holes (6). The wood part on the ceiling hides the electric wires.

A drawing table for A0 format paper
The table had to take minimum space when it was tidied up. And, several level of inclination were needed. Idecided to hang the table on the wall, behind a door.
The 3D system's model and the wall
The rack and pinion system
And a support for some furniture

A camera for a kite
The system and its actuator control the rotation :
A second actuator manages the zoom
An a third actuator controls the camera's trigger

A pole for camera
The main problem was to keep the camera horizontal.
The camera and the electric motors.
The two electric motors which control the rotations. The main stress was the system's weight.
There are some bugs in the model due to the part library.
