Small Scale Bogie Design Team_LS

NOV 14th - Small Scale Bogie Improvements Team Continuing from last weeks flanged wheel design, after increasing the angle to 25 degrees I was able to achieve passive turning. However, the dramatic increase of angle lead to excessive rocking back and fourth of the wheels. While not perfect the concept is proving feasible with more angles to be tested. Some concerns is that inconsistencies in the track may cause results to vary in some areas but with the small scale track team's efforts in improving the bending process the function of the wheels will most likely succeed. A comparison of pros and cons of using the wheels and differential is required for further development towards a final design. I received information from professor Furman and his guest that bricklink.com has a wide selection of Lego parts that will aid in gear selection to ensure functional gear trains for using bevel gears with the differential. Additionally, the small scale track team and I visited Daniel Bol

NOV 7th - Small Scale Bogie Improvements Team Within this week I tested the use of flanged conical wheels to assess the feasibility of using them for passive turning on the track. The initial design was referenced to an existing design that had a slight angle to the wheel of about 3 degrees. Two wheels were attached to an axle and by gravity was allowed to roll down a curved track. The wheels unfortunately did not move as desired and rather continued in a straight line. A new set of wheels will be tested with a greater angle. The updated design is shown below which has a 25 degree angle. Updated Conical Wheels

Oct. 31 Small-Scale Bogie Team The controls team and I talked about the selected  gimbal motor. Some concerns were raised about it not having a shaft and upon further investigation it was found that half of the motor enclosure would rotate not just the shaft. This will make mounting the motor difficult and we should look for alternatives. The need for a functioning test track and Bogie set up are hitting high demand and will most likely be the small scales topic for discussion among other things. As far as inductive charging the integration will be lead by the controls team with little Bogie involvement as it does not dorectly effect Bogie design.
