+# Robot assembly
+
+This file contains assembly instructions for building the robots and soldering the electronics.
+
+## Components
+
+The robot consists of the following components:
+* [Adafruit Mini 3-Layer Round Robot Chassis Kit](https://www.adafruit.com/product/3244)
+* [Wemos D1 mini](https://aliexpi.com/41SY)
+* [Wemos D1 mini battery shield](https://aliexpi.com/sNwB)
+* [Wemos D1 mini motor shield (v1.0.0)](https://aliexpi.com/wngF)
+* LiPo battery
+
+In addition you will need the following tools:
+* A soldering iron
+* Solder wire
+* Heat shrink tube
+* Some wires
+* Battery connectors (female)
+* Velcro tape
+* Self adhesive tape
+* Isolation tape
+* Pin headers
+
+For the camera based position detection of the robots you will need:
+* A camera
+* A printer
+* Paper
+* Cardboard
+
+## Assembly instructions
+
+#### Robot chassis
+Assemble the chassis according to the instructions provided by adafruit ([see here](https://learn.adafruit.com/tri-layer-mini-round-robot-chassis-kit)).
+
+### Soldering the electronics
+1. Solder on two rows of 8 male pin headers to the D1 mini

+
+2. Solder on two rows of 8 female pin headers to the battery shield
+
+3. Solder on two rows of 8 female pin headers to the motor shield as well as a single row of bent pins. Make sure they are soldered on the right way around.
+4. In addition solder a jumper to the motor shield to connect the RTS and 3V pin. This will become important later on. Also solder the I2C bridge.
+    
+ - Note: 
+3. Connect the + pin of the connector from the battery shield to the + pin of the motor shield. 
+
+For this cut some small piece of wire and remove the isolation on both ends. then twist the ends and put some solder on both ends. Cut a piece of isolation and wrap it around the wire. Make sure you do this before soldering on the second end of the wire.
+After this is done, repeat the same with the - connection. Please make sure that you do not reverse the polarity!
