For building a Poppy Ergo Jr, you will need:
-
6x robotis XL-320
-
6x XL cable (if possible 1 longer for the base)
-
1x TTL cable
-
1 external power supply able to output 7.5V at least 2A for the motors (see here for details)
-
1x small electronic board (see the electronic section)
-
many OLLO rivets (between 4 and 12 per motor)
-
4x OLLO Pulley-L and their rivets
-
1x OLLO Tool
-
1x Raspberry Pi 2 with its power supply
All the links to products we provide are from our local distributor but feel free to choose your own.
- Use the OLLO Tool for the rivets, it's really convenient.
- Do not forget to put wires between motors while building the robot!
- Always align the horn with the motor before assembling them! Otherwise your Poppy Ergo Jr will look all weird.
Connect the longest cable to one XL-320 motor. Connect a regular cable to the other side.
Mount the motor on the 3D printed base. The wires should go out from the back.
Mount the U_horn_to_horn part.
Mount another motor on top.
The OLLO Pulley is inside and you should assemble it with the bigger rivet. Bonus, you can watch this step in slow motion.
Do not forget the cable!
Mount both shift_one_sides on the motors.
Add another motor on top. Make sure to have the pulley on the same side.
Mount the U_side_to_horn on a new motor.
Mount it on top of the previous assembly. The nose of the motor should be on the other side of the base.
Mount two other shift_one_sides and a motor. Repeat this twice. All the pulley should still be on the same side.
