Roboslam parts have been sourced from various suppliers to keep costs to a minimum. The list below changes the approach slightly in that it tries to keep the number of suppliers to a minimum instead while still maintaining a low price. Some of the components ship in packs of 10 or more so the kit price below is based on a user buying kits in blocks of 10. Some components such as rolls of wire, packs of diodes etc. come in such units that they can supply a lifetime’s worth of building.
Orders from dx.com can take up to a month to deliver however shipping is free
Other suppliers such as Farnell offer similar products and ship for free if you order more than €20 worth of components
Other possible supplier: Rapid electronics
Discalimer: Every effort has been made to ensure that these components are suitable for constructing a RoboSlam kit. The author does not accept responsibility for
variations in component specifications and prices. Please provide feedback if you encounter a problem so the community can benefit from your experience.
