Mechanics

LeBot James is powered by two DC-Motors from Faulhaber and is stabilised with two ball transfer units. The ball transfer units allow for simple driving, precise positioning and allow LeBot to turn on a dime.
To successfully receive passes from our partner team we fitted LeBot with a funnel. With an upturned lip we prevent the squash ball from rolling out of the funnel.
A shot with pinpoint accuracy is possible with our launch apparatus. With two additional Faulhaber Motors, similar to a tennis ball launcher, the ball is ejected. The leading rail has a modest decline which in turn allows for optimal firing conditions.

Electronics

All electronic components were installed on a singular four layer printed circuit board. With no other connections to different circuit boards needed, the thus compensated space was used for mechanical components.
For navigation LeBot has 6 infrared sensors which detect the lines on the playfield, assuring that LeBot is always aware of his surroundings. There is a further IR-sensor to check if LeBot is in ball possession. Three Time-of-Flight-Sensors help LeBot to spot obstacles on the field, which in turn allows him to dodge them. Opponents can be detected from up to 30 cm away. For parallel orientation to the edge of the playing field, there were two limit switches installed to the rear end.


Information Technology

The Software allows LeBot James and Roberto from Team 02 to communicate so that they can outplay the opposition. The communication occurs via WLAN module. The Robots inform each other when they are in ball possesion or when they are open for a pass.

Our game plan can be viewed on the picture below. The green lines are the robots movements and the blue lines represent ball passes. The notion behind it is that we focus on one side of the playing field. In the picture below our robot, LeBot James (Team 06), will carry out step 2 and 6. His end position is in front of the basket. LeBot would complete the passes 1, 5 and shoot into the basket. Roberto from Team 02 would execute passes 3 and 7 as well as drive 4. The second setting occurs when Roberto has initial ball control, in which case we would perform the same strategy just mirrored at the centre of the playing field.
