The uncompensated temperature of the BMP180 is incorrectly converted to a 16-bit signed value, instead of a 32-bit signed value (long). Since the data is 16-bits wide and can therefore not be negative, the easy fix would be to do the following:

sip.js(1128): uncompensated = uint16(data[0], data[1]);

The current RoomMemberQueryFilter doesn't support query by wxid (id of Contact), can we support this?

Describe the solution you'd like
Add id as a string type in RoomMemberQueryFilter
Describe alternatives you've considered

1. Find all contacts for the room and find out the matched id
2. Load the contact by id fir

The default MIS_DONE_BEHAVE value for Rovers and Boats is 0 ("Hold" mode). For boats we should make the default Loiter to avoid the boat drifting off.

DirectCollocation only supports continuous-time systems. (It's not that we haven't implemented it yet,; the notion of the time derivative of a trajectory which is fundamental to the DirectCollocation algorithm doesn't make sense in discrete time). If someone passes in a discrete time system, the intended helpful guard/message [here](https://github.com/RobotLocomotion/drake/blob/b7c0497cb120dd5

All the crossroads in village_winter have a different texture compared to the roads, which looks kinda odd. Would be nice to have something more consistent.
